Sensitivity studies to betas and Delta Gamma_s using the full Bs->Jpsiphi angular analysis at the LHCb

The Bs->Jpsiphi channel will determine the Bs mixing phase betas and the decay width difference Delta Gamma_s. We present a study of the sensitivity with which these parameters can be measured at the LHCb detector. In this analysis CP eigenstates are separated using decay product angular informat...

description The Bs->Jpsiphi channel will determine the Bs mixing phase betas and the decay width difference Delta Gamma_s. We present a study of the sensitivity with which these parameters can be measured at the LHCb detector. In this analysis CP eigenstates are separated using decay product angular information. We extend previous results which used the single transversity angle to the full three decay angle analysis. We find both a quantitative and qualitative improvement in the precision which may be obtained on all parameters. In addition, we found the mistag fraction omega_tag may be obtained from the data themselves in the full angular analysis.
