Search for T, CP, and CPT violation in B0-B0 mixing with inclusive dilepton events.
We report the results of a search for T, CP, CPT, and violation in B0-B0 mixing using an inclusive dilepton sample collected by the BABAR experiment at the PEP-II factory. Using a sample of 232 x 10(6) BB pairs, we measure the T and CP violation parameter |q/p| - 1 = (-0.8 +/- 2.7(stat) +/- 1.9(syst) x 10(-3), and the CPT and CP parameters Imz = (13.9 +/- 7.3(stat) +/- 3.2(syst)) x 10(-3) and D...
متن کاملul 2 00 1 B 0 d B 0 d Mixing and CPT tests at Belle Talk given at “ Frontiers in
We present results on the mixing parameter ∆md and tests of the CPT symmetry in the B0 dB 0 d mixing from the time evolution of dilepton events on the Υ(4S) resonance. The analysis is based on a 5.9 fb−1 data sample collected by the Belle detector at the KEKB accelerator from January to July of 2001. We obtain ∆md = 0.463 ± 0.008 (stat) ± 0.016 (syst) ps−1. No evidence for CPT violation is foun...
متن کاملSearch for CP violation in B0-B0 mixing using partial reconstruction of B0→D*- Xℓ+ νℓ and a kaon tag.
We present results of a search for CP violation in B0- B0 mixing with the BABAR detector. We select a sample of B0→D*- Xℓ+ ν decays with a partial reconstruction method and use kaon tagging to assess the flavor of the other B meson in the event. We determine the CP violating asymmetry ACP≡[N(B0B0)-N(B0B0)]/[N(B0B0)+N(B0B0)]=(0.06±0.17(-0.32)(+0.38))%, corresponding to ΔCP=1-|q/p|=(0.29±0.84(-1....
متن کاملCharm at Belle
With 10fb −1 data from Belle, the results of b to c and u decays have been represented here. Several decay modes have been studied, which include charmonium, semileptonic decay and Cabibbo-suppressed decays mode. The preliminary results and the measurements of KM matrix elements will also be presented here.
متن کاملSome Tests on Cpt Invariance
We first briefly review tests on CP T invariance based on the consequences of the CPT theorem and then present some possible CP T tests due to exotic models in which some of the CPT conditions are lost, such as those without hermiticity.
