Abstract: The upward-going muon flux (Eμ > 1 GeV) has been measured with the underground detector MACRO at LNGS. The total number of measured events is compatible at the 8% c.l. with the expected one. Moreover, the zenith angular distribution of the measured flux does not match the expectation showing a deficit in the vertical direction where the apparatus performance is best known. Assuming an oscillation hypothesis with parameters in the range recently suggested to solve the atmospheric neutrino problem, the agreement increases, but not significantly. The results of an indirect dark matter search for a signal of WIMPs from the core of the Sun and of the Earth are given. Neutrino astronomy with MACRO is giving interesting results regarding possible high energy neutrino emission from pointlike sources and coincidences of neutrino events with γ-ray bursts.

Abstract: MACRO is a large area multiple component detector located deep underground in Hall B of the Laboratori Nazionali del Gran Sasso in Italy. Its active components consist of tanks of liquid scintillator and planes of limited streamer tubes. In addition, there are two planar areas covered with passive track-etch plastics. The full detector measures 72 m × 12 m × 9.6 m providing a large sensitive area for the detection of penetrating particles. Multiple electronics systems provide triggering on particles over a wide range of velocities, in particular, for slowly moving massive particles such as grand unified magnetic monopoles. MACRO is sensitive to relativistic particles as well as ones whose velocities are as low as 10 −4 c. Various portions of the MACRO detector have been operational since 1989. Various data sets have been analyzed and although no monopoles have been found, stringent flux limits have been set using a variety of techniques. This paper summarizes the capabilities of MACRO for monopole detection and presents some experimental results which have been obtained to date.

Abstract: A measurement of the underground muon decoherence function has been performed using the multiple muon events collected by the MACRO detector at the Gran Sasso National Laboratory. A detector-independent analysis is presented for different zenith regions and rock depths; this allows direct comparison with any model of hadronic interactions. The measured decoherence function is compared with the predictions of a Monte Carlo simulation based on data taken by recent collider experiments. © 1992 The American Physical Society.

Abstract: We perform an indirect search for Weakly Interacting Massive Particles (WIMPs) using the MACRO detector to look for neutrino-induced upward-going muons resulting from the annihilation of WIMPs trapped in the Sun and Earth. The search is conducted in various angular cones centered on the Sun and Earth to accommodate a range of WIMP masses. No significant excess over the background from atmospheric neutrinos is seen and limits are placed on the upward-going muon fluxes from Sun and Earth. These limits are used to constrain neutralino particle parameters from supersymmetric theory, including those suggested by recent results from DAMA/NaI., Comment: 14 pages, 7 figures, submitted to Phys.

Abstract: We present a measurement of the underground decoherence function using multi-muon events observed in the MACRO detector at Gran Sasso at an average depth of 3800 hg/cm**2. Muon pair separations up to 70 m have been measured, corresponding to parent mesons with P_t < 1-2GeV/c. The accuracy of the measurement is such that the possible contribution of rare processes, such as mu + N ----> mu + N + mu- + mu+, can be experimentally studied. The measured decoherence function is compared with the predictions of the hadronic interaction model of the HEMAS Monte Carlo code. Good agreement is obtained. We interpret this agreement to indicate that no anomalous P_t components in soft hadron-Nucleus and Nucleus-Nucleus collisions are required by the MACRO experimental data., 38 pages, Latex, 10 figures, Corrected typos

Abstract: Using data collected by the MACRO experiment during the years 1989-1996, we show evidence for the shadow of the moon in the underground cosmic ray flux with a significance of 3.6 sigma. This detection of the shadowing effect is the first by an underground detector. A maximum-likelihood analysis is used to determine that the angular resolution of the apparatus is 0.9+/-0.3 degrees. These results demonstrate MACRO's capabilities as a muon telescope by confirming its absolute pointing ability and quantifying its angular resolution., Comment: 14 pages, 8 figures Submitted to Phys.

Abstract: A search for heavily ionizing particles produced in j5p collisions at √s = 1.8 TeV was performed at the Fermilab Tevatron collider using plastic track detectors. No highly ionizing particles were observed. The experiment places a limit on the production of magnetic monopoles with mass m < 850 GeV at σ < 2 10-34 cm2 (95% confidence level). The level of radiation present in the collider tunnel is discussed. © 1990 IOP Publishing Ltd.

Abstract: MACRO is designed to make a multiply redundant search for GUT magnetic monopoles over a wide velocity range. The 100 MHz pulse height recorder and synchronous encoder (PHRASE) and the energy reconstruction processor (ERP) are two components of that search, both based on the MACRO liquid scintillator. They are sensitive to monopoles with or without captured nuclei in the range beta similar to 10(-3) to beta similar to 1, Here, the performance of these systems is discussed, including also analysis methods and background evaluations.

Abstract: Using 5.33 x 10(6) single muons collected in 1.46 x 10(4) live hours by MACRO during the period 1991-1994, we have searched for a correlation between variations in the underground muon rate, N-mu, and seasonal temperature variations in the atmosphere. These correlations are found to be present with high statistical significance. Analysis of the relatively complete December 1992-December 1994 subset of the data yields a value for the temperature coefficient, alpha(T) = (T/N-mu)(partial derivative N-mu/partial derivative T) = 0.83 +/- 0.13. Analysis of the total data Set gives consistent results. We have compared this result with the hypothesis that the muons observed in MACRO come from pion decays alone. Although our result is consistent with the 'pion only' hypothesis, a discussion of the sensitivity of our data sample to the kaon component of the cascades leading to observed muons underground will also be presented.

Abstract: Multimuon data from the MACRO experiment at Gran Sasso have been analyzed 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 array measurements. The spectral indexes of the fitted energy spectrum are 2.56[Formula presented]0.05 for [Formula presented]500 TeV and 2.9[Formula presented]0.3 for [Formula presented]5000 TeV with a gradual change at intermediate energies. The average mass number shows little dependence on the primary energy below 1000 TeV, with a value of 10.1[Formula presented]2.5 at 100 TeV. At higher energies the best fit average mass shows a mild increase with energy, even though no definite conclusion can be reached taking into account errors. The fitted spectra cover a range from [Formula presented] 50 TeV up to several thousand TeV. © 1997 The American Physical Society.

Abstract: Upward-going muon events collected with the lower half of the MACRO detector have been analyzed in order to search for Weakly Interacting Massive Particles possibly trapped in the core of the Sun and of the Earth. No statistically significant signal could be discriminated over the possible fluctuations of the atmospheric neutrino background. Assuming a particular neutralino model, the explorable neutralino mass region has been considered.

Abstract: We report on the first measurement of the flux of upgoing muons resulting from interactions of atmospheric neutrinos in the rock below MACRO. The ratio of the observed to the expected number of events integrated over all nadir angles is 0.73 ± .09 stat. ± .06 sys. ± .12 theor. . The flux of upgoing muons as a function of nadir angle is presented and compared to Monte Carlo expectations. At the 90% confidence level, the data are consistent with no neutrino oscillations or some possible oscillation hypothese with the parameters suggested by the Kamiokande contained-event analysis.

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: 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: 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: 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 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: 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: 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: Charged multiplicity and π 0 cross sections for π − p inelastic interactions at 70 GeV/ c are presented. The data were obtained from an exposure of the BEBC bubble chamber equipped with a track sensitive target (TST) to an unseparated negative beam at the CERN SPS. About 10 000 events were used for the charged multiplicity study, and about 2000 Dalitz pairs for the π 0 production analysis. A total of 12 e + e − pairs with a mass higher than the π 0 mass were found and analysed in terms of η or ω Dalitz pairs or decay pairs of vector mesons. Comparisons with data at other energies are made in terms of charged prong, π 0 cross sections, and of multiplicity parameters. The moments of longitudinal and transverse momentum distributions of the π 0 are determined and compared to the predictions of quark counting rule models.

Abstract: Charged hadron multiplicity distributions in $$\bar v_\mu n$$ and $$\bar v_\mu p$$ interactions in the energy range $$5< E_{\bar v}< 150GeV$$ GeV are presented. They are obtained from about $$6000\bar v_\mu $$ charged current events produced in BEBC filled with deuterium. Multiplicity moments are studied as a function of the invariant mass of the hadronic systemW. Results on multiplicity distributions in the forward and backward directions in the hadronic c.m.s. are presented and discussed within the framework of the quark parton model. Values for the average charge of the forward jet are also determined and compared with other experimental data.

Abstract: The reactions $$\bar vD \to \mu ^ + n\pi ^ - (p_s )$$ and $$\bar vD \to \mu ^ + p\pi (n_s )$$ have been studied at antineutrino energies varying from 5 to 200 GeV. The cross sections for these reactions were determined from 545 and 300 selected events for each channel respectively. The first reaction was used for the study of the decay properties of the Δ resonance that dominates this channel. The experimental results have been compared with the theoretical predictions of Rein and Sehgal [9] and of Fogli and Nardulli [10]. Using the first model we obtained for the axial form factor parameterM a =1.01±0.05 GeV/c2. With this value the model is in agreement with the experimentaldσ/dQ 2 distributions forQ 2>0.25 GeV2 and with the distributions of the invariant hadronic massW. The isospin structure of the one-pion production has been investigated and compared with the results of other experiments.

Abstract: Inclusive production of the meson resonance ϱ0 in high-energy neutrino and antineutrino charged current (CC) interactions in deuterium was studied using the bubble chamber BEBC exposed to the CERN-SPS wide band neutrino and antineutrino beams. In a sample of 10693 charged current ν μ D and 13 758νμD interactions we found 0.222 ± 0.014ϱ0 per charged current event. Thr production of f mesons is smaller than 0.03 per CC event (90% confidence level). The ϱ0 production properties are studied in terms of charged hadron multiplicity, of the mass of the hadronic system and of various kinematical variables. The experimental results are compared with the predictions of the Lund fragmentation model, whose predictions are about 50% higher than the experimental values.

Abstract: The ratios of neutral-current to charged-current cross sections of v and v interactions, seperately, on proton and neutron targets have been measured. The Big European Bubble Chamber (BEBC), filled with deuterium and equipped with an external muon identifier (EMI) and an internal picket fence (IPF), was exposed to the CERN SPS (anti)neutrino wide-band beam. The measured ratios are Rvp= = 0.405 ± 0.024 ± 0.021, Rvn = 0.243 ± 0.013 ± 0.016, Rvp = 0.301 ± 0.027 ± 0.024 and Rvn = 0.490 ± 0.050 ± 0.037. (The first error is statistical and the second systematic). From combinations of these ratios the following neutral-current chiral coupling constants have been determined: uL2 = 0.099 ± 0.018 ± 0.008, dL2 = 0.202 ± 0.020 ± 0.019, uR2 = 0.020 ± 0.016 ± 0.009 and dR2 = 0.002 ± 0.017 ± 0.010. These results agree with the predictions of the SU(2) × U(1) standard electroweak model. Assuming ϱ = 1, the corresponding value of sin2 θ w is found to be 0.247 ± 0.029, whereas a two-parameter fit to the data yields sin2θw = 0.243 ± 0.046 and ϱ = 0.996 ± 0.041.

Abstract: From the analysis of 5630 v υ and of 1372 v π charged current interactions, obtained in the BEBC bubble chamber filled with deuterium and exposed to the CERN wide band antineutrino beam, the ratios of cross section on neutron and photon targets have been measured and found to be R  σ ν)/σ v p = 0.51 ± 0.01 (±0.03) , and R  σ( ν n )/σ( v p ) = 22.2 ± 0.12 (±0.25) The dependence of these ratios on the x scaling variable shows, in a direct way, that the momentum distribution of the majority quark, up(x) = dn(x), is broader than that of the minority quark, un(x) = dp(x).

Abstract: The transverse momentum properties of charged hadrons produced in charged current ν and $$\bar v$$ deuterium interactions are studied. The variation of withW 2,Q 2,x F andz 2 is analyzed. A study of transverse momentum balance shows that soft gluon emission and some quark primordial transverse momentum with ≃(0.4 GeV/c)2 are needed to balance highp t particles. Distributions ofp tin andP tout in and out of the event plane are presented. A three jet structure is observed for events withW 2>50 (GeV2) and with a highp t track, which is compatible with models taking into account hard gluon emission.

Abstract: Results are presented on the multiplicity distributions of charged hadrons produced in νn, νp, {Mathematical expression} and {Mathematical expression} charged-current interactions for the hadronic energy range 2GeV≤W≤14GeV (corresponding approximately to the neutrino energy range 5GeV≤E v≤150GeV). The experimental distributions are analysed in terms of binomial distributions. With increasing hadronic energy we find a smooth transition from an ordinary binomial via Poissonian to the negative binomial function. KNO scaling holds approximately for the multiplicity distribution for the whole phase space. Data on the multiplicity distributions for neutral-current interactions are also presented. © 1989 Società Italiana di Fisica.

Abstract: Quark fragmentation functions are studied in charged current ν and ν interactions in deuterium. The W2, Q2 and y dependences are compared with the predictions of first order QCD and with those of higher twists. The W2 dependence is a small effect in our kinematical range and our data are well linked to the higher W2 muon scattering experiment. The Q2 dependence of non singlet fragmentation functions is well reproduced by first order QCD but part of this dependence could be due to some low W kinematical effect. The y-z factorization breaking seems to be a low W effect but a small higher twist term, as predicted by Berger cannot be excluded.

Abstract: Data from an exposure of the BEBC bubbe chamber filled with deuterium to a wideband antineutrino beam have been used to obtain the x - and y -distributions for antineutrino scattering on the neutron and proton. The y -distribution have been fitted in order to determine the fraction of momentum carried by quarks and antiquarks of given flavour and their x - dependence.

Abstract: The total νμ and ν μ nucleon charged-current cross sections have been measured in BEBC filled with deuterium and exposed to the wide-band neutrino and antineutrino beams at the CERN-SPS. Assuming a linear energy dependence for the cross sections, σ = aE(−ν, we obtained the coefficients a ν N = 0.62 ± 0.05 and a ν N = 0.33 ± 0.03 (in units of 10 −38 cm 2 /GeV) , where the quoted error is mainly systematic. The ratio of the cross sections is σ ν N /σ ν N = 0.53 ± 0.03 . We also determined the ratio of the charged-current cross section for neutrino interactions on neutrons and protons R = σνn/σνp = 2.10 ± 0.08 (statistical) ±0.22 (sysetmatic). The dependence of R on the variables x, y and Eν is discussed.
