Measuring CP violation in $B^{0}_{s} \to \phi\phi$ with LHCb
Sensitivity studies to the CP-violating parameters of the decay B_s->phi phi with the LHCb experiment are presented. The decay proceeds via a b->s s anti-s gluonic-penguin quark transition, which is sensitive to contributions from beyond the Standard Model particles. A time-dependent angular a...

| description | Sensitivity studies to the CP-violating parameters of the decay B_s->phi phi with the LHCb experiment are presented. The decay proceeds via a b->s s anti-s gluonic-penguin quark transition, which is sensitive to contributions from beyond the Standard Model particles. A time-dependent angular analysis of simulated data leads to an expected statistical uncertainty of 6 degrees on any new physics induced CP-violating phase for a sample corresponding to 2 fb^-1 of integrated luminosity. The expected precision on sin2beta from the related decay B^0->phi K0S is also discussed. |
