Bs−Bs mixing with a chiral light quark action
نویسندگان
چکیده
We study the B 0 s − B 0 s mixing amplitude in Standard Model by computing the relevant hadronic matrix element in the static limit of lattice HQET with the Neuberger light quark action. In the quenched approximation, and after matching to the MS scheme in QCD, we obtain B MS B s (m b) = 0.940(16)(22). c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.

Lattice measurement of BBs with a chiral light quark action
Bs − Bs mixing is highly important in testing the Standard Model (SM) and constrains strongly its extensions by bounding the unitarity triangle. Since it is a flavor changing neutral process it occurs through loops so that the corresponding mixing amplitude is a sensitive measure of |Vts| and |Vtb|, as the major SM loop contribution comes from t-quark. The mixing of weak interaction eigenstates...
متن کاملRecent Results in Chiral Perturbation Theory for Mesons Containing a Single Heavy Quark
Chiral symmetry and heavy quark symmetry constrain the interactions of mesons containing a single heavy quark with low-momentum pions. Chiral corrections to the Isgur-Wise function for Bs → D s versus B → D semileptonic decay, the ratio of heavy meson decay constants fDs/fD or fBs/fB, the amplitudes for Bs−Bs versus B0−B 0 mixing, and the heavy meson mass splittings are calculated in chiral per...
متن کاملExcited Heavy-Light Systems and Hadronic Transitions
A detailed study of orbital and radial excited states inD,Ds, B and Bs systems is performed. The chiral quark model provides the framework for the calculation of pseudoscalar meson (π,K, ...) hadronic transitions among heavy-light excited and ground states. To calculate the excited states masses and wavefunctions, we must resort to a relativistic quark model. Our model includes the leading orde...
متن کاملChiral Perturbation Theory for fDS/fD and BBS/BB
The decay constants for the D and DS mesons, denoted fD and fDS respectively, are equal in the SU(3)V limit, as are the hadronic amplitudes for BS−BS and B0−B 0 mixing. The leading SU(3)V violating contribution to (fDS/fD) and to the ratio of hadronic matrix elements relevant for BS − BS and B − B 0 mixing amplitudes are calculated in chiral perturbation theory. We discuss the formalism needed ...
متن کاملB s − B s mixing in an SO ( 10 ) SUSY GUT model ⋆
We perform a renormalisation group analysis of the SO(10) model proposed by Chang, Masiero and Murayama, which links the large atmospheric neutrino mixing angle to loop-induced transitions between right-handed b and s quarks. We compute the impact on Bs−Bs mixing and find that the mass difference in the Bs system can exceed its Standard Model value by a factor of 16. PACS. 12.60.Jv supersymmetr...
