Use and misuse of ChPT in the heavy-light systems
Damir Becirevic, Svjetlana Fajfer, Jernej Kamenik
We discuss the range of validity of ChPT when applied to the systems of heavy-light mesons. Having in mind the recent experimental evidence according to which the heavy-light scala…
The Ademollo-Gatto theorem for lattice semileptonic decays
Damir Becirevic, Guido Martinelli, Giovanni Villadoro
We present the results of the calculation of the Kl3 semileptonic form factor at zero momentum transfer, f(0), obtained at one-loop in partially quenched Chiral Perturbation Theory…
SU(3)-breaking effects in kaon and hyperon semileptonic decays from lattice QCD
D. Becirevic, D. Guadagnoli, G. Isidori +7
We discuss the result of a recent quenched lattice calculation of the K -> pi vector form factor at zero-momentum transfer, relevant for the determination of |V_us| from K-> pi l n…
Renormalization Constants of Quark Operators for the Non-Perturbatively Improved Wilson Action
D. Becirevic, V. Gimenez, V. Lubicz +3
We present the results of an extensive lattice calculation of the renormalization constants of bilinear and four-quark operators for the non-perturbatively O(a)-improved Wilson act…
Impact of the finite volume effects on the chiral behavior of fK and BK
Damir Becirevic, Giovanni Villadoro
We discuss the finite volume corrections to fK and BK by using the one-loop chiral perturbation theory in full, quenched, and partially quenched QCD. We show that the finite volume…
HQET with chiral symmetry on the lattice
Damir Becirevic, Juan Reyes
We show that by combining the static heavy quark action with the Neuberger action for the light quark, the renormalisation of the heavy-light bilinear and four-quark operators, com…
