Abstract

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,324 new measurements from 878 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. Particle properties and search limits are listed in Summary Tables. We give numerous tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, Probability and Statistics. Among the 120 reviews are many that are new or heavily revised, including a new review on High Energy Soft QCD and Diffraction and one on the Determination of CKM Angles from B Hadrons. The Review is divided into two volumes. Volume 1 includes the Summary Tables and 98 review articles. Volume 2 consists of the Particle Listings and contains also 22 reviews that address specific aspects of the data presented in the Listings. The complete Review (both volumes) is published online on the website of the Particle Data Group (pdg.lbl.gov) and in a journal. Volume 1 is available in print as the PDG Book. A Particle Physics Booklet with the Summary Tables and essential tables, figures, and equations from selected review articles is available in print and as a web version optimized for use on phones as well as an Android app.

Using data from previous editions, plus 3,062 new measurements from 721 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, Probability and Statistics. Among the 117 reviews are many that are new or heavily revised, including those on Pentaquarks and Inflation. The complete Review is published online in a journal and on the website of the Particle Data Group (http://pdg.lbl.gov). The printed PDG Book contains the Summary Tables and all review articles but no longer includes the detailed tables from the Particle Listings. A Booklet with the Summary Tables and abbreviated versions of some of the review articles is also available.

Abstract

This biennial Review summarizes much of Particle Physics. Using data from previous editions, plus 1726 new measurements from 512 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summarize searches for hypothetical particles such as Higgs bosons, heavy neutrinos, and supersymmetric particles. All the particle properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and reviews of topics such as the Standard Model, particle detectors, probability, and statistics. Among the 119 reviews are many that are new or heavily revised including those on neutrino mixing, CP violation in K, D, and B mesons, Vcb, the new exotic Θ(1540) particle, extra-dimensions, grand unified theories, cosmic background radiation, dark matter, cosmological parameters, and big bang cosmology. A booklet is available containing the Summary Tables and abbreviated versions ofsome of the other sections of this full Review. All tables, listings, and reviews (and errata) are also available on the Particle Data Group website: http//pdg.lbl.gov. ©2004 Regents of the University of California.

Abstract

This biennial Review summarizes much of Particle Physics. Using data from previous editions, plus 2205 new measurements from 667 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summarize searches for hypothetical particles such as Higgs bosons, heavy neutrinos, and supersymmetric particles. All the particle properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and reviews of topics such as the Standard Model, particle detectors, probability, and statistics. This edition features expanded coverage of CP violation in B mesons and of neutrino oscillations. For the first time we cover searches for evidence of extra dimensions (both in the particle listings and in a new review). Another new review is on Grand Unified Theories. A booklet is available containing the Summary Tables and abbreviated versions of some of the other sections of this full Review. All tables, listings, and reviews (and errata) are also available on the Particle Data Group website: http://pdg.lbl.gov.

Abstract

This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summarize searches for hypothetical particles such as Higgs bosons, heavy neutrinos, and supersymmetric particles. All the particle properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and reviews of topics such as the Standard Model, particle detectors, probability, and statistics. Among the 108 reviews are many that are new or heavily revised including those on neutrino mass, mixing, and oscillations, QCD, top quark, CKM quark-mixing matrix, Vud & Vus, Vcb & Vub, fragmentation functions, particle detectors for accelerator and non-accelerator physics, magnetic monopoles, cosmological parameters, and big bang cosmology. A booklet is available containing the Summary Tables and abbreviated versions of some of the other sections of this full Review. All tables, listings, and reviews (and errata) are also available on the Particle Data Group website: pdg.lbl.gov.

Abstract

A detailed description of the analysis of neutral kaons decaying to e pi nu is given, based on the complete set of data collected with the CPLEAR experiment, Using a novel approach involving initially strangeness-tagged K-0 and (K) over bar (0), time-dependent decay-rate asymmetries were measured, These asymmetries enabled T- and CPT-violation parameters to be measured in the context of a systematic study. The highlights of this study arc the first direct observation of T violation and the direct determination of the CPT parameter Re(delta) with an accuracy improved by two orders of magnitude with respect to the current value.

Abstract

Neutral-kaon decays to pi e nu were analysed to determine the q(2) dependence of the K-e3(0), electroweak form factor f(+). Based on 365612 events, this form factor was found to have a linear dependence on q(2) with a slope lambda(+) = 0.0245 +/- 0.0012(stat) +/- 0.0022(syst). (C) 2000 Published by Elsevier Science B.V.

Abstract

We apply a forward dispersion relation to the regeneration amplitude for kaon scattering on C-12 using all available data. The CPLEAR data at low energies allow the determination of the net contribution from the subthreshold region which turns out to be much smaller than earlier evaluations, solving a long standing puzzle.

Abstract

The CPT-violation parameters Re(delta) and Im(delta) determined recently by CPLEAR are used to evaluate the K-0-(K) over bar(0) mass and decay-width differences, as given by the difference between the diagonal elements of the neutral-kaon mixing matrix (M - i Gamma/2). The results - (M-K0K0 - M0 ($) over bar 0)) = (- 1.5 +/- 2.0) x 10(-18) GeV and (Gamma(K0K0) - Gamma(($) over bar 0 ($) over bar 0)) = (3.9 +/- 4.2) x 10(-18) GeV - are consistent with CPT invariance. The CPT invariance is also shown to hold within a few times 10(-3)-10(-4) for many of the amplitudes describing neutral-kaon decays to different final states. (C) 1999 Elsevier Science B.V.

Abstract

We report the results of the CPLEAR experiment on CP-, T-, and CPT-symmetries in the neutral kaon system. CP-violation parameters are given for the K-0, (K) over bar(0) –> 2 pi, 3 pi decay channels. For the first time, T-violation is measured by a direct method using semileptonic decays. The CPT symmetry is tested through the parameters Im(delta) with a precision of 10(-5) and Re(delta) with a precision of a few 10(-4). With these two measurements, the difference in mass and width of K-0 and (K) over bar(0) are bound to within 10(-18) GeV. In the limit of CPT invariance in the neutral kaon decays, the K-0 and (K) over bar(0) masses are equal within 10(-19) GeV.

Abstract

We study pi pi correlations in the exclusive reaction (p) over bar p –> 2 pi(+)2 pi(-)pi(0) at rest with complete reconstruction of the kinematics for each event. Inclusive and differential distributions properly normalized show an enhancement for small invariant masses M++,M– of like-pion pairs. An even stronger enhancement is seen for the double differential distributions for low pion-pair masses. The signal is strongest when the pi(0) energy is large and much weaker when this energy is small. Dynamical models with resonances in the final state are confronted with the data. For the kinematic situation where the rho 3 pi channel is important the simulation predicts a large pion correlation for the double differential density, qualitatively explaining the observed bahaviour. The stochastic HBT mechanism is not supported by these findings for the exclusive annihilation reaction studied.

Time-dependent decay rate asymmetries are measured between initially tagged K-0 and (K) over bar(0) and for different regions of the phase space. These asymmetries, resulting from the interference between the CP-coaserving decay amplitude of K-L and the decay amplitude of K-S - either CP-violating or CP-conserving - allow the determination of the K-S parameters eta(+-0) (CP-violating) and lambda (CP-conserving), and also of the main isospin components of the K-S decay amplitude. The branching ratio of K-S –> pi(+)pi(-)pi(0) (CP-conserving) is deduced directly from lambda. In addition, we extract the slope parameters describing the energy dependence of the K-L –> pi(+)pi(-)pi(0) Dalitz plot. The whole set of out. results fits well within the current phenomenological picture of the neutral-kaon system including CP violation and Chiral Perturbation Theory (ChPT).

Abstract

We study pi pi correlations in the exclusive reaction (p) over bar p –> 2 pi(+)2 pi(-) at rest measured by the CPLEAR experiment. Avoiding the introduction of an arbitrary reference sample, we analyse differential distributions for equal charge pion pairs removing the phase-space factor event by event. A peak at small relative momenta is most pronounced for large total momentum of the pair. The physical implications of bosonic symmetrization for the properties of the pion source, in particular its radius, are briefly discussed. The two extremes considered are the chaotic Hanbury-Brown-Twiss mechanism and the coherent Skyrmion model.

Abstract

We report on the first observation of time-reversal symmetry violation through a comparison of the probabilities of (K) over bar(0) transforming into K-0 and K-0 into (K) over bar(0) as a function of the neutral-kaon eigentime t. The comparison is based on the analysis of the neutral-kaon semileptonic decays recorded in the CPLEAR experiment. There, the strangeness of the neutral kaon at time t = 0 was tagged by the kaon charge in the reaction –> K (+/-) pi (+/-) K-0 ((K) over bar(0)) at rest, whereas the strangeness of the kaon at the decay time t = tau was tagged by the lepton charge in the final state. An average decay-rate asymmetry [R((K) over bart=00 –> e+pi-nut=tau) - R(Kt=00 –> e-pi+t=tau)/R((K) over bart=00 –> e+pi-nut=tau) + R(Kt=00 –> e-pi+t=tau)] = (6.6 +/- 1.3stat +/- 1.0syst) X 10-3 was measured over the interval 1 tau(S) < tau < 20 tau(S), thus leading to evidence for time-reversal non-invariance.

Abstract

The CPLEAR experiment measured the eigentime-dependent asymmetry in the rates of initially tagged (K) over bar(o) and K-o decaying to pi(o) pi(o) pi(o) in order to study the interference between the CP-violating K-S and the CP-conserving K-L decay amplitudes. Without assuming CPT invariance, we obtain for the CP-violation parameter eta(ooo) the values Re(eta(ooo))= 0.18 +/- 0.14(stat.) +/- 0.06(syst.) and Im(eta(ooo)) = 0.15 +/- 0.20(stat) +/- 0.03(syst:) Requiring Re(eta(ooo)) to be equal to Re(epsilon) we obtain Im(eta(ooo)) = -0.05 +/- 0.12(stat.) +/- 0.05(syst:) The corresponding upper limit for the branching ratio of the K-S –> pi(o) pi(o) pi(o) decay is deduced to be BKs –> pi o pi o pi o

Abstract

The EPR-type strangeness correlation in the K-0 system produced in the reaction –> K-0 at rest has been tested using the CPLEAR detector. The strangeness was tagged via strong interaction with absorbers away from the creation point. The results are consistent with the QM non-separability of the wave function and exclude a spontaneous wave-function factorisation ar creation (CL > 99.99%). (C) 1998 Elsevier Science B.V.

Abstract

We have improved by two orders of magnitude the Limit currently available for the CPT violation parameter Re(delta). To this purpose we have analyzed the full sample of neutral-kaon decays to e pi nu recorded in the CPLEAR experiment, where the strangeness of the neutral kaons was tagged at production and decay time. An appropriate function of the measured decay rates, including information from the analysis of pi(+)pi(-) decay channel, gives directly Re(delta). The result Re(delta) = (3.0 +/- 3.3(stat) +/- 0.6(syst)) X 10(-4) is compatible with zero. Values for the parameters Im(delta), Re(x(-)) and Im(x(+)) were also obtained.

Abstract

The CPLEAR experiment measured time-dependent decay-rate asymmetries of K-0 and (K) over bar(0) decaying to pi(+)pi(-)pi(0) in order to study the interference between the decay amplitudes of K-S(0) - either CP-violating or CP-conserving - and the CP-conserving K-L(0) decay amplitude. From the analysis of the complete data set we find for the CP-violating parameter eta(+-0), Re((+-0)) = (-2 +/- 7 stat. (+4)(-1) syst.) x 10(-3), Im(eta(+-0)) = (-2 +/- 9 stat. (+2)(-1) syst.) x 10(-3) and for the CP-conserving parameter lambda, Re(lambda) = (+28 +/- 7 stat. +/-3 syst.) x 10(-3), Im(lambda) = (-10 +/- 8 stat. +/- 2 syst.) x 10(-3). From the latter, the branching ratio of the CP-conserving (KS)-S-0 –> pi(+)pi(-)pi(0) decay is deduced to be B = (2.5(-1.0)(+1.3) stat. (+0.5)(-0.6) systs.) x 10(-7). (C) 1997 Elsevier Science B.V.

Abstract

The neutral kaon regeneration amplitude in carbon at momenta between 250 and 750 MeV/c was determined by measuring the interference of inherent and coherently regenerated K-S amplitudes. This interference appears in the rates of initially pure (tagged) K-0 and (K) over bar(0) decaying to pi(+)pi(-) after crossing a carbon absorber. (C) 1997 Published by Elsevier Science B.V.

Abstract

The interference between CP-conserving K-S and K-L –> pi(+)pi(-)pi(0) decay amplitudes was observed by studying the decay rate asymmetries between initial K-0 and (K) over bar(0) separately for the phase space regions E(CM)(pi(+)) > E(CM)(pi(-)) and E(CM)(pi(+)) < E(CM)(pi(-)) For the parameter lambda we found Re(lambda) = 0.036 +/- 0.010(stat.)(-0.003)(+0.002)(syst.) and Im(lambda) consistent with zero, leading to a branching ratio B = [4.1(-1.9)(+2.5)(stat.)(-0.6)(+0.5)(syst.)] x 10(-7) for the CP-conserving K-S –> pi(+)pi(-)pi(0) decay.

Abstract

The CPLEAR collaboration has constructed a detector at CERN for an extensive programme of CP-, T- and CPT-symmetry studies using K-0 and produced by the annihilation of in a hydrogen gas target. The K-0 and are identified by their companion products of the annihilation K(+/-)pi(-/+) which are tracked with multiwire proportional chambers, drift chambers and streamer tubes. Particle identification is carried out with a liquid Cherenkov detector for fast separation of pions and kaons and with scintillators which allow the measurement of time of flight and energy loss. Photons are measured with a lead/gas sampling electromagnetic calorimeter. The required antiproton annihilation modes are selected by fast online processors using the tracking chamber and particle identification information. All the detectors are mounted in a 0.44 T uniform field of an axial solenoid of diameter 2 m and length 3.6 m to form a magnetic spectrometer capable of full on-line reconstruction and selection of events. The design, operating parameters and performance of the subdetectors are described.

Abstract

The CPLEAR experiment at CERN studies the CP, T and CPT symmetries in the neutral-kaon system by measuring the rate asymmetries between the decays of initially pure K-0 and (K-0) over bar states. Using data taken between 1900 and mid 1994, precise measurements of η(+ -) phi(+ -) and Delta m are reported. The comparison of phi(+ -) with the superweak phase gives one of the most sensitive tests of CPT invariance and leads to a new limit on the K-0-(K-0) over bar mass difference.

Abstract

{CP violation has been observed as a time-dependent rate asymmetry between the decays --> pi(0) pi(0) and K-0 --> pi(0) pi(0), where the neutral kaons are produced with definite and individually known strangeness in --> K(+)pi(-) or --> K(0)K(-)pi(+). A special technique for the data analysis has been developed. The values obtained for phi(00) and \textbackslash{}eta(00)\textbackslash{} are in agreement with those of previous measurements of CP violation.}

Abstract

We use fits to recent published CPLEAR data on neutral kaon decays to pi(-)pi(-) and pi e nu to constrain the CPT-violation parameters appearing in a formulation of the neutral kaon system as an open quantum-mechanical system. The obtained upper limits of the CPT-violation parameters are approaching the range suggested by certain ideas concerning quantum gravity.

Abstract

{We report the first determination of CP violation parameters from particle-antiparticle asymmetry in the decay of neutral kaons into two charged pions. Observation of such an asymmetry is direct proof of CP violation. A fit to the asymmetry enabled a determination of the parameter-eta+- to be made, yielding the result \textbackslash{}eta+-\textbackslash{} = {[}2.32 +/- 0.14 (stat. ) +/- 0.03 (syst.)] X 10(-3) and phi+- = 42.3-degrees +/- 4.4-degrees (stat.) +/- 0.4-degrees (syst. ), with an additional uncertainty of +/-1.0-degrees due to the error on the present published value of DELTA-m, the K(L)0-K(S)0 mass difference. The magnitudes of both statistical and systematic errors will be significantly reduced in the future.}

Abstract

The CPLEAR experiment will measure CP violation parameters in the neutral kaon system, using a low energy antiproton beam from the Low Energy Antiproton Ring (LEAR) at CERN. One of its subdetectors, the Particle Identification Detector (PID), makes a fast separation of pions and kaons, which is essential for the experiment. This article describes the design of the PID and its performance during beam tests and during initial runs at LEAR. A pion rejection efficiency of 99.7% for the first level trigger (after 60 ns) is found in the relevant momentum region.

Abstract

This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summarize searches for hypothetical particles such as Higgs bosons, heavy neutrinos, and supersymmetric particles. All the particle properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and reviews of topics such as the Standard Model, particle detectors, probability, and statistics. Among the 108 reviews are many that are new or heavily revised including those on neutrino mass, mixing, and oscillations, QCD, top quark, CKM quark-mixing matrix, Vud & Vus , Vcb & Vub , fragmentation functions, particle detectors for accelerator and non-accelerator physics, magnetic monopoles, cosmological parameters, and big bang cosmology. A booklet is available containing the Summary Tables and abbreviated versions of some of the other sections of this full Review. All tables, listings, and reviews (and errata) are also available on the Particle Data Group website: pdg.lbl.gov.

46. Cytotoxic activity of murine resident peritoneal cells against Listeria monocytogenes-infected hepatocytes in vitro.

Abstract

Sterile immunity to the Gram-positive facultative intracellular bacterium Listeria monocytogenes critically depends on cytotoxic CD8+ T lymphocytes. However, the cytotoxic cell population able to kill infected cells before specific T cells are generated is not well characterised. Based on histological observations and the use of monoclonal antibodies abrogating the CD11b/CD18-dependent cellular influx into infected organs as well as granulocyte-depleting antibodies, some authors favour PMNs as being most important in the preimmune lysis of L. monocytogenes-infected hepatocytes. However, these experiments do not conclusively demonstrate that this cell population is indeed directly cytotoxic to infected cells. The aim of this study was to establish an experimental approach for a more detailed analysis of cell-cell interactions in the preimmune phase of listeriosis. We here present an ex vivo-in vitro plaque-forming assay, which enables the quantitative analysis and experimental modulation of the cytotoxic activity of murine (BALB/c) peritoneal cells (PC) against L. monocytogenes-infected hepatocytes (ATCC TIB 73). Using this system, we show that naive resident peritoneal macrophages are able to kill L. monocytogenes-infected hepatocytes. The plaque-forming capacity increased in the presence of interferon gamma (IFN-gamma) and was dissociable from nitric oxide (NO) production. These findings suggest a new, i.e. cytotoxic role for macrophages in the early phase of host defence against a facultative intracellular bacterium.
