Abstract

The results obtained by measuring the inclusive distributions of the Feynman variable x and the transversemomentum for the production of K mesons in proton-nucleus interactions at 70 GeV/ c for three targets (C, Si, and Pb) are presented. The mass-number ( A) dependence of the cross section for K -meson production is studied. The measured value of the exponent α in the formula σ ∼ A agrees within the errors with its counterpart at higher energies. With the aid of the A dependence, the measured yield of K mesons at x = 0 is compared with the yield of K and K mesons in the proton-proton reaction at 70 GeV/ c. The inclusive spectra of longitudinal and transverse variables for K-meson production are contrasted against the predictions of the FRITIOF and UrQMD models. [ABSTRACT FROM AUTHOR]

Abstract

In this paper a method to perform direct T and CPT symmetry tests is briefly discussed, exploiting the Einstein-Podolsky-Rosen correlations of neutral kaon pairs produced at a ø-factory. The KLOE-2 experiment at DAΦNE, the Frascati ø-factory, could make statistically significant tests of this type. [ABSTRACT FROM AUTHOR]

Abstract

We present an improved determination of the CP and CPT violation parameters Re(epsilon) and Im(delta) based on the unitarity condition (Bell-Steinberger relation) and on recent results from the KLOE experiment. We find Re(epsilon) = (159.6 \pm 1.3)10^-5 and Im(delta) = (0.4 \pm 2.1)10^-5, consistent with no CPT violation., Submitted to JHEP

Abstract

We report a measurement of the direct CP violation asymmetry parameter A g in charged kaon decays K ± → π ± π + π − by the NA48/2 experiment at the CERN SPS. The experiment has been designed not to be limited by systematics in the asymmetry measurement. Using 1.67 × 10 9 such decays collected during the 2003 run, the charge asymmetry in the Dalitz plot linear slope parameter g has been measured to be A g = ( 1.7 ± 2.9 ) × 10 −4 . The precision of the result is limited by the statistics used.

Abstract

The direct CP violation parameter Re(epsilon'/epsilon) has been measured from the decay rates of neutral kaons into two pions using the NA48 detector at the CERN SPS. The 2001 running period was devoted to collecting additional data under varied conditions compared to earlier years (1997-99). The new data yield the result: Re(epsilon'/epsilon) = (13.7 +/- 3.1) times 10^{-4}. Combining this result with that published from the 1997, 98 and 99 data, an overall value of Re(epsilon'/epsilon) = (14.7 +/- 2.2) times 10^{-4} is obtained from the NA48 experiment., Comment: 19 pages, 5 figures, to be published in Physics Letters B

Abstract

A value of (-6.1 +- 0.9_{stat} +- 0.5_{syst})*10^{-3} is obtained for the quadratic slope parameter h in the K_L -> 3\pi^0 decay Dalitz plot at the NA48 experiment at the CERN SPS. The result is based on 14.7*10^6 fully reconstructed K_L -> 3\pi^0 -> 6\gamma decays. This is the most precise measurement of any of the Dalitz plot slope parameters in the charged and neutral kaon decays so far., Comment: 13 pages, 3 figures, 2 tables

Abstract

The rate of the decay of the neutral K meson into KL0 → μμγ has been measured with the NA48 detector at the CERN SPS. A total of 59 events has been observed with an estimated background of 14 events. The overall Kaon flux was determined to be 1.2 × 109. This observation corresponds to a branching ratio of (3.4 ± 0.6stat ± 0.4sys × 10-7. Using this branching ratio the parameter αK* describing the relative strength of the two contributing amplitudes to this decay, through intermediate pseudoscalar or vectorlike mesons, was measured to be αK* = -0.04+-0.21+0.24.
