Form factors of the and semileptonic decays with twisted mass lattice QCD
S. Di Vita, B. Haas, V. Lubicz +3
We present lattice results for the vector and scalar form factors of the semileptonic decays D -> π\ell ν_ell and D -> K \ell ν_\ell in the physical range of values of squared four…
Vector and scalar form factors for K- and D-meson semileptonic decays from twisted mass fermions with Nf = 2
S. Di Vita, B. Haas, F. Mescia +3
We present lattice results for the form factors relevant in the K -> pion and D -> pion semileptonic decays, obtained from simulations with two flavors of dynamical twisted-mass fe…
Soft Photon Problem in Leptonic B-decays
Damir Becirevic, Benjamin Haas, Emi Kou
We point out at the peculiarity of B --> mu nu decay, namely the enhancement of the soft photon events which originate from the structure dependent part of the B --> mu nu gamma am…
Pseudoscalar decay constants of kaon and D-mesons from Nf=2 twisted mass Lattice QCD
B. Blossier, P. Dimopoulos, R. Frezzotti +12
We present the results of a lattice QCD calculation of the pseudoscalar meson decay constants fpi, fK, fD and fDs, performed with Nf=2 dynamical fermions. The simulation is carried…
D*-->Dpi and D*-->Dgamma decays: Axial coupling and Magnetic moment of D* meson
Damir Becirevic, Benjamin Haas
The axial coupling and the magnetic moment of D*-meson or, more specifically, the couplings g(D*Dpi) and g(D*Dgamma), encode the non-perturbative QCD effects describing the decays…
D-decays with unquenched Lattice QCD
Benjamin Haas
We discuss the recent progress in computing the D-meson decay constant and D->pi l nu form factors from the lattice QCD simulations with Nf=2 dynamical using Wilson quarks. We repo…
