, 2002 These lectures describe the most important theoretical methods in b-physics. We discuss the formalism of effective weak Hamiltonians, heavy quark effective theory, the heavy quark expansion for inclusive decays of b-hadrons and, finally, the more recent ...

Phenomenological study of heavy hadron lifetimes
Journal of High Energy Physics, 2018 The lifetimes of bottom and charmed hadrons are analyzed within the framework of the heavy quark expansion (HQE). Lifetime differences arise from the spectator effects such as weak W-annihilation and Pauli interference. Spectator effects originating from

Heavy-light mesons from a flavour-dependent interaction
Physics Letters BWe introduce a new framework for the physics of heavy-light mesons, whose key element is the effective incorporation of flavour-dependent contributions into the corresponding bound-state and quark gap equations.

The time-dependent CP asymmetry in B 0 → K resγ → π+π− K s 0 γ $$ {K}_s^0\gamma $$ decays
Journal of High Energy Physics, 2019 The time-dependent CP asymmetry in B 0 → K resγ → π+π− K Sγ is sensitive to the photon polarisation in the quark level process b → sγ. While this polarisation is predominantly left-handed in the standard model, it could be modified by the existence of ...

Sizable time-reversal violating effects in bottom baryon decays
Journal of High Energy Physics, 2022 We study time-reversal (T) asymmetries in the charmless two-body decays of antitriplet bottom baryons. We find that in B b → B n P with B b = ( Ξ b − $$ {\Xi}_b^{-} $$ , Ξ b 0 $$ {\Xi}_b^0 $$ , Λ b ) and B n (P) a octet baryon (pseudoscalar meson), the ...

Heavy Domain Wall Fermions: The RBC and UKQCD charm physics program
EPJ Web of Conferences, 2018 We review the domain wall charm physics program of the RBC and UKQCD collaborations based on simulations including ensembles with physical pion mass. We summarise our current set-up and present a status update on the decay constants fD, fDs, the charm ...
