Abstract

Neutral kaons provide one of the systems most sensitive to quantum mechanics and CPT violation. Models predicting quantum mechanics violation, also related to CPT violation, have been tested at the CPLEAR and KLOE experiments. In this report results of CPLEAR obtained by studying the time evolution of single and two entangled kaons are reviewed. New or improved limits on decoherence and CPT violation parameters have been obtained by KLOE studying the quantum interference in the channel ϕ → K S K L → π + π − π + π − . No deviations from the expectations of quantum mechanics and CPT symmetry have been observed.

Abstract

The Cryogenic Magnetic Detector (CMD-2) at the VEPP-2M collider has collected a total integrated luminosity of about 30 pb −1 . The cross sections of e + e − annihilation into hadrons were measured in the energy range from 0.37 to 1.39 GeV. A Monte Carlo generator has been constructed which incorporates the vacuum polarization effects with radiative corrections. The generator simulates production of Bhabha events, two charged pions and muons as well as photon jets. Radiative corrections in the first order of α are taken into account exactly. By means of the structure-function method the leading logarithmic contributions are calculated in all orders of α . The theoretical accuracy of the cross section calculation is estimated to be better than 0.2%.

Abstract

The current status of the updated results from the CMD-2 detector is presented. The cross sections of e + e − annihilation into hadrons were measured in the c.m. energy range from 0.37 to 1.39 GeV and are based on the total integrated luminosity of about 30 pb −1 . Results of refitting experimental data for the ρ, ω and mesons are reviewed.

Abstract

The first results of the luminosity measurement with the CMD-3 detector at the VEPP-2000 e + e − collider are presented. The luminosity was measured using two different processes e + e − → e + e − and e + e − → γ γ , that allowed to better understand and estimate the systematic accuracy which was found to be ∼2%. The analysis of the data was done on the integrated luminosity about 20 pb−1. A Monte-Carlo Generator Photon Jets (MCGPJ) [A.Arbuzov et al., EPJ C46, 689 (2006); S.Actis et al., EPJ C66, 585 (2010)] to simulate Bhabha scattering events as well as production of two photons was adopted for analysis of the data. A theoretical precision of these cross sections with radiative corrections (RC) is estimated to be better than 0.2%.
