Abstract: The vertical underground muon intensity has been measured in the slant depth range 3200-7000 hg cm-2 (standard rock) with the completed lower part of the MACRO detector at the Gran Sasso laboratory, using a large sample of data. These observations are used to compute the surface muon flux and the primary ''all-nucleon'' spectrum. An analysis of systematic uncertainties introduced by the interaction models in the atmosphere and the underground propagation of muons is presented. A comparison of our results with published data is also presented. © 1995 The American Physical Society.

Abstract: We are developing a liquid xenon calorimeter for the MEG experiment. This experiment, to be performed at the Paul Scherrer Institut (PSI) in Villigen (CH), was designed by an Italian-Japanese-Russian-Swiss collaboration to search for the /spl mu//sup +//spl rarr/e/sup +//spl gamma/ decay, forbidden in the standard model of electroweak and strong interactions. The photon four momentum is to be measured by an innovative C-shaped 800 litres liquid xenon calorimeter read by more than 800 photo-multiplier tubes. An absorption length for Xe scintillation light larger than 100 cm has been measured. The performance of such a detector has been measured using a large volume prototype (100 litres) in a test beam at PSI, using high energy photons from decays of neutral pions from a charge exchange reaction of negative pions on protons. A resolution of 5% FWHM was obtained.

Abstract: An 800L liquid xenon scintillation $\gamma$ ray detector is being developed for the MEG experiment which will search for $\mu^+\to\mathrm{e}^+\gamma$ decay at the Paul Scherrer Institut. Absorption of scintillation light of xenon by impurities might possibly limit the performance of such a detector. We used a 100L prototype with an active volume of 372x372x496 mm$^3$ to study the scintillation light absorption. We have developed a method to evaluate the light absorption, separately from elastic scattering of light, by measuring cosmic rays and $\alpha$ sources. By using a suitable purification technique, an absorption length longer than 100 cm has been achieved. The effects of the light absorption on the energy resolution are estimated by Monte Carlo simulation., Comment: 18 pages, 10 figures (eps). Submitted to Nucl. Instr. and Meth. A

Abstract: A study of the primary cosmic ray composition in the energy range 5ṡ1014−5ṡ1015 eV is performed through the analysis of the deep underground muons and of the e.m. component of Extensive Air Showers detected in coincidence by the MACRO and EAS-TOP experiments at the Gran Sasso Laboratory. We conclude that: a) pure proton and Iron primary beams are excluded by the experimental data; b) a fraction of nuclei heavier than Helium is necessary to explain the experimental data both below and above the knee; c) a mixed composition, obtained a priori from extrapolations of the spectra directly measured below 100 TeV, yields a reasonable account of the observations up to the knee of the primary spectrum.

Abstract: A search for slowly moving magnetic monopoles in the cosmic radiation was conducted from October 1989 to November 1991 using the large liquid scintillator detector subsystem of the first supermodule of the MACRO detector at the Gran Sasso underground laboratory. The absence of candidates established an upper limit on the monopole flux of 5.6×10-15 cm-2 sr-1 s-1 at 90% confidence level in the velocity range of 10-4

Abstract: We report on the simultaneous observation of atmospheric erenkov light by a prototype five telescope array, GRACE, (Gran Sasso Air erenkov Experiment) with deep underground muons in the MACRO (Monopole Astrophysics and Cosmic Ray Observatory). The telescope array was deployed at Campo Imperatore above the Gran Sasso Laboratory for a run completed in the fall of 1992. The total live time for the combined surface-underground operation was ∼100 h during which more than 300 events were seen in coincidence. The efficacy of this technique to monitor the electromagnetic and penetrating muon components of a cosmic-ray-induced cascade is discussed. © 1994 The American Physical Society.

Abstract: Muon events collected with the streamer tube system of MACRO have been used to study the vertical muon intensity and to search for astrophysical point sources. New upper limits on the muon fluxes coming from source candidates have been obtained. The μ pair distance distribution and multimuon rates are presented and compared with Monte Carlo predictions for different primary cosmic rays composition models.

Abstract: Multimuon data from the MACRO experiment at Gran Sasso have been analysed using a new method which allows one to estimate the primary cosmic ray fluxes. The estimated all-particle spectrum is higher and flatter than the one obtained from direct measurements but is consistent with EAS measurements. The average mass number shows a weak dependence on the primary energy below 10^{6} GeV. Even within large uncertainties our data support a possible increase of the average mass number at higher energies.

Abstract: The cosmic ray primary composition in the energy range between 10(15) and 10(16) eV, i.e., around the "knee" of the primary spectrum, has been studied through the combined measurements of the EAS-TOP air shower array (2005 m a. s.l., 10(5) m(2) collecting area) and the MACRO underground detector (963 m.a.s.l., 3100 m w.e. of minimum rock overburden, 920 m(2) effective area) at the National Gran Sasso Laboratories. The used observables are the air shower size (N-c) measured by EAS-TOP and the muon number (N-mu) recorded by MACRO. The two detectors are separated on average by 1200 m of rock, and located at a respective zenith angle of about 30degrees. The energy threshold at the surface for muons reaching the MACRO depth is approximately 1.3 TeV. Such muons are produced in the early stages of the shower development and in a kinematic region quite different from the one relevant for the usual N-mu - N-e studies. The measurement leads to a primary composition becoming heavier at the knee of the primary spectrum, the knee itself resulting from the steepening of the spectrum of a primary light component (p, He) of Deltay = 0.7 +/- 0.4 at E-0 similar to 4 x 10(15) eV. The result confirms the ones reported from the observation of the low energy muons at the surface (typically in the GeV energy range), showing that the conclusions do not depend on the production region kinematics. Thus, the hadronic interaction model used (CORSIKA/QGSJET) provides consistent composition results from data related to secondaries produced in a rapidity region exceeding the central one. Such an evolution of the composition in the knee region supports the "standard" galactic acceleration/propagation models that imply rigidity dependent breaks of the different components.. and therefore breaks occurring at lower energies in the spectra of the light nuclei.

Abstract: Using data collected by the MACRO experiment from 1989 to the end of its operations in 2000, we have studied in the underground muon flux the shadowing effects due to both the Moon and the Sun. We have observed the Moon shadowing effect with a significance of 6.5 sigma and the Sun shadowing effect with a significance of 4.3 sigma. The observed displacement of the Sun shadow, due to the configurations of the solar and interplanetary magnetic fields, has been used to quote the antiproton/proton flux limits for primaries of about 20 TeV energy., 23 pages, 11 figures, submitted to Astrop.Phys

Abstract: The MACRO underground detector at Gran Sasso Laboratory recorded 60 million secondary cosmic ray muons from February 1989 until December 2000. Different techniques were used to analyze this sample in search for density excesses from astrophysical point-like sources. No evidence for DC excesses for any source in an all-sky survey is reported. In addition, searches for muon excess correlated with the known binary periods of Cygnus X-3 and Hercules X-1, and searches for statistically significant bursting episodes from known gamma ray sources are also proved negative., Comment: 18 pages, 12 figures

Abstract: We have analyzed 44.3M single muons collected by MACRO from 1991 through 2000 in 2,145 live days of operation. We have searched for the solar diurnal, apparent sidereal, and pseudo-sidereal modulation of the underground muon rate by computing hourly deviations of the muon rate from 6 month averages. We find evidence for statistically significant modulations with the solar diurnal and the sidereal periods. The amplitudes of these modulations are, 18 pages, 8 of which are figures, 1 is a table.

Abstract: The MACRO detector was located in the Hall B of the Gran Sasso underground Laboratories under an average rock overburden of 3700 hg/cm^2. A transition radiation detector composed of three identical modules, covering a total horizontal area of 36 m^2, was installed inside the empty upper part of the detector in order to measure the residual energy of muons. This paper presents the measurement of the residual energy of single and double muons crossing the apparatus. Our data show that double muons are more energetic than single ones. This measurement is performed over a standard rock depth range from 3000 to 6500 hg/cm^2., 28 pages, 9 figures

Abstract: We present a study of the correlations in the arrival times of about 1016 single and multiple muons detected by the first two MACRO supermodules. The time correlations, from milliseconds to several hundrends of seconds, have been analyzed in terms of the random distribution, with which they are consistent. An analysis of the arrival times (up to 180 ns) of the muons from the same multimuon event is also given. © 1992.

Abstract: We present the analysis of multiple-muon events collected with one supermodule (1013 h live time) and two supermodules (1195 h live time) of the MACRO detector at Gran Sasso, Italy. Multimuon rates are shown to be sensitive to primary-cosmic-ray energies between 50 TeV and several thousand TeV. Experimental data are compared with the expected rates from two composition models: a light (i.e., proton-rich) and a heavy (i.e., Fe-rich) composition. The predictions are based on a Monte Carlo simulation of the hadronic interactions of cosmic-ray nuclei, followed by a detailed tracking of the muons through the rock and the experimental apparatus. The results show good sensitivity of the MACRO detector to primary composition. The data exhibit a preference towards the light composition model. © 1992 The American Physical Society.

Abstract: A negative search using 1/12 of the eventual MACRO detector has yielded nuclearite flux limits of 1.1[times]10[sup [minus]14] cm[sup [minus]2] sr[sup [minus]1] s[sup [minus]1] for 10[sup [minus]10][lt][ital m][lt]0.1 g, and 5.5[times]10[sup [minus]15] cm[sup [minus]2] sr[sup [minus]1] s[sup [minus]1] for [ital m][gt]0.1 g. We have modified the formula of De Rujula and Glashow for the light yield of nuclearites to include the uv light absorbed and reemitted in the visible region, and proved that the MACRO sensitivity extends almost to the escape velocity of the Earth. Our flux limit, therefore, can be used to address nuclearites that are possibly trapped in the solar system.

Abstract: The interaction of a Grand Unification Magnetic Monopole with a nucleon can lead to a barion-number violating process in which the nucleon decays into a lepton and one or more mesons (catalysis of nucleon decay). In this paper we report an experimental study of the effects of a catalysis process in the MACRO detector. Using a dedicated analysis we obtain new magnetic monopole (MM) flux upper limits at the level of $\sim 3\cdot 10^{-16} cm^{-2} s^{-1} sr^{-1}$ for $1.1\cdot 10^{-4} \le |\beta| \le 5\cdot 10^{-3}$, based on the search for catalysis events in the MACRO data. We also analyze the dependence of the MM flux limit on the catalysis cross section., Comment: 12 pages, Latex, 10 figures and 2 Tables

Abstract: We describe a search method for fast moving ($\beta > 5 \times 10^{-3}$) magnetic monopoles using simultaneously the scintillator, streamer tube and track-etch subdetectors of the MACRO apparatus. The first two subdetectors are used primarily for the identification of candidates while the track-etch one is used as the final tool for their rejection or confirmation. Using this technique, a first sample of more than two years of data has been analyzed without any evidence of a magnetic monopole. We set a 90% CL upper limit to the local monopole flux of $1.5 \times 10^{-15} cm^{-2} s^{-1} sr^{-1}$ in the velocity range $5 \times 10^{-3} \le \beta \le 0.99$ and for nucleon decay catalysis cross section smaller than $\sim 1 mb$., Comment: 29 pages (12 figures).

Abstract: We present the final results obtained by the MACRO experiment in the search for GUT magnetic monopoles in the penetrating cosmic radiation, for the range $4\times 10^{-5}< \beta < 1$. Several searches with all the MACRO sub-detectors (i.e. scintillation counters, limited streamer tubes and nuclear track detectors) were performed, both in stand alone and combined ways. No candidates were detected and a 90% Confidence Level (C.L.) upper limit to the local magnetic monopole flux was set at the level of $1.4\times 10^{-16}$ cm$^{-2}$ s$^{-1}$ sr$^{-1}$. This result is the first experimental limit obtained in direct searches which is well below the Parker bound in the whole $\beta$ range in which GUT magnetic monopoles are expected., Comment: 12 pages, Latex, 9 figures and 2 Tables

Abstract: The angular distribution of upward-going muons produced by atmospheric neutrinos in the rock below the MACRO detector show anomalies in good agreement with two flavor neutrino-mu ==> neutrino-tau oscillations with maximum mixing and Delta m**2 around 0.0024 eV**2. Exploiting the dependence of magnitude of the matter effect on oscillation channel, and using a set of 809 upward-going muons observed in MACRO, we show that the two flavor neutrino-mu ==> neutrino-sterile oscillation is disfavored with 99% C.L. with respect to neutrino-mu ==> neutrino-tau., 7 pages 4 figures Submitted to Physics Letters B

Abstract: High energy gamma ray astronomy is now a well established field and several sources have been discovered in the region from a few GeV up to several TeV. If sources involving hadronic processes exist, the production of photons would be accompanied by neutrinos too. Other possible neutrino sources could be related to the annihilation of WIMPs at the center of galaxies with black holes. We present the results of a search for point-like sources using 1100 upward-going muons produced by neutrino interactions in the rock below and inside the MACRO detector in the underground Gran Sasso Laboratory. These data show no evidence for a possible neutrino point-like source or for possible correlations between gamma ray bursts and neutrinos. They have been used to set flux upper limits for candidate point-like sources which are in the range 10^-14-10^-15 cm-2 s-1., Comment: 37 pages, 15 figures, replacement due to a typo in tab. 6, AASLaTex, submitted to ApJ

Abstract: Combined measurements of extensive air showers at the surface and high-energy muons deep underground have been initiated at the Gran Sasso Laboratory. The underground detector is the first supermodule of MACRO (area = 140 ${\mathrm{m}}^{2}$, depth = 3100 m of water equivalent, ${E}_{\ensuremath{\mu}}g1.3$ TeV) and the surface detector is the EAS-TOP array (altitude 2000 m above sea level, total enclosed area $A\ensuremath{\sim}{10}^{5}$ ${\mathrm{m}}^{2}$). We discuss the correlation technique, the comparison between the shower parameters as determined by the two detectors, and some of the characteristics of the reconstructed events.

76. A Long-Base Search for Neutrino Oscillations at a Reactor; the CHOOZ Experiment

Author: C. Bemporad
Subjects: Physics, Nuclear physics, Neutron capture, Physics::Instrumentation and Detectors, Detector, High Energy Physics::Experiment, Cosmic ray, Neutrino, Scintillator, CHOOZ, Neutrino oscillation, Calorimeter
Abstract: CHOOZ, the first long-base reactor-neutrino vacuum-oscillation experiment, has been tuned in 1996 and is running since early 1997. The liquid scintillator calorimeter is located in a tunnel, at a distance of 1 Km from the neutrino source, and is protected by a 300 mwe rock cover, which strongly reduces the cosmic ray generated background. The experiment wants to probe Δ m 2 down to 10−3 eV 2 and sin 22θ in the interval 1 ↔ 0.1. After measuring the no-reactor background, the experiment collected data for several months, at an increasing and now at full, reactor power. Results of the neutrino oscillation search will be published in autumn 1997; information relative to the detector performance and to the data taking is presented.

Abstract: Initial results are presented from CHOOZ, a long-baseline reactor-neutrino vacuum-oscillation experiment. Electron antineutrinos were detected by a liquid scintillation calorimeter located at a distance of about 1 km. The detector was constructed in a tunnel protected from cosmic rays by a 300 MWE rock overburden. This massive shielding strongly reduced potentially troublesome backgrounds due to cosmic-ray muons, leading to a background rate of about one event per day, more than an order of magnitude smaller than the observed neutrino signal. From the statistical agreement between detected and expected neutrino event rates, we find (at 90% confidence level) no evidence for neutrino oscillations in the electron antineutrino disappearance mode for the parameter region given approximately by deltam**2 > 0.9 10**(-3) eV**2 for maximum mixing and (sin(2 theta)**2) > 0.18 for large deltam**2., 13 pages, Latex, submitted to Physics Letters B

Abstract: The MACRO underground experiment has started a systematic experimental study of the structure of a very high multiplicity event sample, with the aim of gaining a better understanding of the features of the high energy showers. We present here two new analyses: a) the analysis of the distribution of the separation between pairs of high multiplicity muons (''decoherence'' function); b) the search for clusters of muons within high multiplicity events. The first results are discussed together with a comparison between the real data and the Monte Carlo predictions.

Abstract: An analysis of the coincident deep underground muon data and of the e.m. component of Extensive Air Showers (EAS) as measured by the MACRO and EAS-TOP experiments at Gran Sasso is presented. Constraints on the primary cosmic ray composition are obtained, with the use of an interaction model that is based on collider data. The possibility of extrapolating the directly measured energy spectra to our energy range is tested.

Abstract: Recent results on muon astronomy from the MACRO experiment at Gran Sasso are presented. An analysis has been performed to search for astrophysical point sources of neutral particles which could produce energetic muons through interactions in the Earth's atmosphere. In this paper, we present results on an all-sky survey for an excess muon flux; searches for steady state and periodic muon signals from several candidate point sources; and a search for a short term variability in the muon flux from the direction of Cygnus X-3.

Abstract: The MACRO detector, located in the underground Gran Sasso Laboratory, had its initial data run from February 27 to May 30, 1989, using the first supermodule (SΩ∼800 m 2 sr ) . Approximately 245 000 muon events were recorded. Here are reported the results of the analysis of penetrating muons which determine the measured vertical muon flux at depths greater than 3000 m.w.e. In addition the data have been used to search for large scale anisotropies.

Abstract: The effects of varying independently the inter-dinode voltages of Philips photomultipliers types 56 AVP and 58 AVP on the linearity and maximum gain obtainable are described. It is found that great improuvements are possible over the performances obtainable with the voltage distributions recommended by the manufacturers and that with voltage distributions optimized separately for each tube it is always possible to at least achieve the maximum performances claimed by the manufacturers. The distributions recommended by them do not fulfill these claims.

Abstract: The results of an experiment to measure the π0 lifetime via the inverse decay process (“Primakoff effect”) are presented. The coherent photoproduction of neutral pions in the reaction γ+Pb→π0+Pb has been measured with very high angular resolution with a π0 detector containing 10 independent counting channels, at the two mean energies 950 and 1000 MeV, using the bremsstrahlung beam of the Frascati electron synchrotron. The angular distributions show a characteristic bumping around the forward direction, giving conclusive evidence for the existence of the Primakoff effect. The results are interpreted in terms of two amplitudes-the electromagnetic and the nuclear one-adding up coherently to give the over-all coherent cross-section. Such a cross-section is expressed in terms of four unknown parameters: the lifetime τ, the phase δ between the electromagnetic and nuclear amplitude, the strengthC of the nuclear amplitude, and the nuclear radiusR0. Neutral-pion reabsorption inside nuclear matter is taken into account, and a χ2 analysis of the data is done in terms of τ, δ,C, andR. The best fit τ value is (0.73±0.105)·10−16s. Systematic errors, as well as the sensitivity of the results to the model used to interpret the data, are extensively discussed and conservatively taken into account.

Abstract: An experiment for determining the η lifetime has been performed at DESY. The cross section for η photo-production has been measured between 0o and 4o, at 4.0 GeV and 5.5 GeV incident γ ray energies and on different target materials (lead, silver, zinc). η's were detected through their γ-γ decays. The production is dominated by the Primakoff effect from which a value of Γγγ= (1.21 ± 0.26) keV is derived.

Abstract: New results are presented on the differential cross-section for the reaction α+p→π0+p, at energies between 600 and 1000 MeV, and c.m. pion angles Θ*π=40° and Θ*π=60°. The present data, together with that at Θ*π=40° already published (11), show an angle-independent position of the second resonance at about 750 MeV. Rather flat angular distributions in the forward c.m. hemisphere are also favoured by these data. On comparing the cross-sections obtained when detecting both the neutral pion and the recoil proton, and when detecting only the latter, estimates of the background of «ghost protons» are obtained, in agreement with the empirical curve proposed in ref. (11).

Abstract: We report on results obtained by operating a system of proportional wire chambers in a high-energy (9–16 GeV/ c ) beam in conjunction with a diffraction dissociation experiment. Single and multitrack efficiency is better than 99%, and firing of two adjacent wires is of the order of 10%. Space resolution is of the order of one-quarter the wire spacing, as expected. Time resolutions of 150 nsec were achieved, and the deadtime is of the order of 250 nsec per wire.

Abstract: A system of eight lead-glass Cerenkov counters, each coupled to a veto scintillation counter, was used at Frascati in a measurement of the Primakoff effect in the π0 photoproduction on complex nuclei (1). The system as a whole is a precision π0 detector: pion angle and energy are measured with a precision near to the limit attainable with present-day techniques. In the first part of the work we have discussed the problem of measuring with high resolution the four-momentum of neutral pion of ≈1 GeV energy. In the second part, a description of the detector is given. Finally, in the third part, the Monte Carlo calculation of the detector efficiency is described.

97. Energy dependence of coherent production of three pions on nuclei between 9 and 15 GeV and comparison with diffractive three-pion production on hydrogen

Abstract: A total of 34 000 coherent events, produced on different target nuclei and at incident pion momenta from 9 to 15 GeV/c, allows us to discuss the energy dependence of the differential cross section and of the three-pion mass spectrum. The comparison with the optical model is satisfactory. This model is then used to determine the total cross section of the unstable three-pion system on nucleons; the result is a value of about 25 mb. The value of the forward differential cross section on nucleons obtained by application of the optical model shows a tendency to increase with incident energy. A similar increase with energy is found for the forward diffractive cross section of three-pion production on hydrogen; the absolute value of this cross section is somewhat higher than the cross section determined from nuclear targets. Also the mass spectrum on nucleons derived from the present experiment is compatible with that produced on hydrogen. Furthermore, there is no evidence for abundant coherent production of A2 and A3. On the other hand, these two resonances seem to be present in the incoherent background.
