Abstract

We present a new measurement of the K-L-K-S mass difference (Delta m) using semileptonic decays of neutral kaons. The measurement yields Delta m = (0.5274 +/- 0.0029(stat.) +/- 0.0005(syst.)) x 10(10)(h) over bar/s.

Abstract

Two-charged-pion correlations were studied in ppBAR (--> 2pi+2pi-npi0, n greater-than-or-equal-to 0) annihilations at rest with the CPLEAR detector at the Low-Energy Antiproton Ring (LEAR) A strong enhancement was found in the production of pairs of like-sign pions with a small value of the relative four-momentum Q, with respect to pairs of unlike-sign pions. The observed enhancement was interpreted as a consequence of the Bose-Einstein symmetrization of the two-pion wave function. The data are well represented by a correlation function parametrized as a double-Gaussian; an exponential parametrization is also statistically acceptable. The value of the correlation strength is found to be > 1. The high-quality large data samples together with the ability for K+/- identification and final-state separation allowed the study of systematic effects impacting on the Q dependence of the correlation function and on the extracted space parameters of the pion sources.

Abstract

Bose-Einstein (BE) correlations between like-sign charged pions were studied in ppBAR annihilations at rest into four-prong events, using data taken with the CPLEAR detector at LEAR (CERN). A strong enhancement was found in the production of pairs of like-sign pions of similar momenta, with respect to the pairs of unlike-sign pions. The observed BE-enhancement was used to extract the values for the strength lambda of the effect and the radius r of the pion emitting source. The extracted value of lambda>1 is of relevant importance and clearly does not depend on the assumed parametrization of the correlation function. The influence of the normalization and fitting procedure, the detector resolution, the resonances production and decay and the neutral-pion multiplicity cuts, on the size of the pion source and the strength of the effect was investigated.

Abstract

The CPLEAR experiment at CERN has been designed to measure CP and T violating effects in the neutral kaon system by observing particle-antiparticle asymmetries. The motivation and the physics program of CPLEAR is presented and first analyses of the K0, k0 to π+π-, π0π0 and π+π-π0 decays are discussed. Special emphasis is given to the recent results of the measurement of the CP violating parameters θsymbol+- and η+- based on first data taken in 1990/1991. © 1993.

Abstract

The method for studying semileptonic neutral kaon decays at CPLEAR is presented together with a preliminary data analysis. For the first time a direct determination of T violation is shown to be possible and low statistics results are given. From the same data the KL-KS mass difference, Δm, the CP violation parameter of KS, εlunates, and the parameter x testing the ΔS = ΔQ rule are also obtained. © 1993.

Abstract

The CPLEAR experiment is aiming at precise CP violation tests using initially pure K0- and K0 beams from the intense source provided by the annihilation of the LEAR p-beam in hydrogen. The strangeness tagging efficiency and the systematic errors have been studied and found to be in agreement with the design specifications. The measurement of the differential time asymmetry of the π+π- decays allowed the direct observation of differences in the decay rates of particles and antiparticles. The CP violating parameters were determined as |ν±| = (2.32 ± 0.14) · 10-3 and ψ± = 42.3° ± 4.4°. First results in the reconstruction and analysis of the neutral kaon decays into two neutral pions and the Ke3 decay are presented. © 1993.

Abstract

The CPLEAR set-up (modified) has been used to determine the KL–KS mass difference by a method where neutral-kaon strangeness oscillations are monitored through kaon strong interactions, rather than semileptonic decays, thus requiring no assumptions on CPT invariance for the decay amplitudes. The result, Δm=(0.5343±0.0063stat±0.0025syst)×1010ℏ/s, provides a valuable input for CPT tests., NR 20160511

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

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 \eta+-\ = [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. Physics Letters B

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

The ratio of the branching fractions for pp→K+K- and pp→π+π- was determined with the CPLEAR detector, by stopping antiprotons in a gaseous hydrogen target at 15 bar pressure. It was found to be BR(K+K-)/BR(π+π-)=0.20 5± 0.016. The fraction of P-wave annihilation at rest at this target density was deduced to be (38±9)%. © 1991.

Abstract

The aim of the CP LEAR experiment is to study symmetry-violation effects, making use of tagged K0's and K0's. The detector, although missing some electronic components, has been operational for a few weeks at the end of 1989 at the CERN Low-Energy Antiproton Ring (LEAR). At the moment, the analysis of the data is in progress. This paper gives a description of the experimental method and of the detector; the sensitivities of some measurements and some preliminary results are also discussed. © 1991.

Abstract

The CPT-violation parameters Re(δ) and Im(δ) determined recently by CPLEAR are used to evaluate the K0– mass and decay-width differences, as given by the difference between the diagonal elements of the neutral-kaon mixing matrix (M−iΓ/2). The results – GeV and 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., NR 20160511

184. A determination of the CP violation parameter η+- from the decay of strangeness-tagged neutral kaons

Abstract

LEAR offered unique opportunities to study the symmetries which exist between matter and antimatter. At variance with other approaches at this facility, CPLEAR was an experiment devoted to the study of CP, T and CPT symmetries in the neutral-kaon system. A variety of measurements allowed us to determine with high precision the parameters which describe the time evolution of the neutral kaons and their antiparticles, including decay amplitudes, and the related symmetry properties. Limits concerning quantum-mechanical predictions (EPR, coherence of the wave function) or the equivalence principle of general relativity have been obtained. An account of the main features of the experiment and its performances is given here, together with the results achieved., NR 20160511

Abstract

The CPLEAR experiment at CERN has directly studied matter and antimatter symmetries via the measurement of the time evolution of K[sup 0] and ...[sup 0]. The CPT violation parameter Re(δ) was directly measured with a precision of a few 10[sup -4] while Im(δ) is determined from the Bell-Steinberger relation, with a precision of 10[sup -5]. The mass and decay-width equality between the K[sup 0] and ...[sup 0] were tested down to the level of 10[sup -18] GeV. [ABSTRACT FROM AUTHOR]
