-improved actions for heavy quarks and scaling studies on quenched lattices
Yong-Gwi Cho, Shoji Hashimoto, Jun-Ichi Noaki +2
We investigate a new class of improved relativistic fermion action on the lattice with a criterion to give excellent energy-momentum dispersion relation as well as to be consistent…
Computing the Adler function from the vacuum polarization function
Hanno Horch, Michele Della Morte, Gregorio Herdoíza +3
We use a lattice determination of the hadronic vacuum polarization tensor to study the associated Ward identities and compute the Adler function. The vacuum polarization tensor is…
The pion vector form factor from lattice QCD and NNLO chiral perturbation theory
Bastian B. Brandt, Andreas Juttner, Hartmut Wittig
We present a comprehensive study of the electromagnetic form factor, the decay constant and the mass of the pion computed in lattice QCD with two degenerate O(a)-improved Wilson qu…
The kaon semileptonic form factor with near physical domain wall quarks
Peter A. Boyle, Jonathan M. Flynn, Nicolas Garron +4
We present a new calculation of the K->pi semileptonic form factor at zero momentum transfer in domain wall lattice QCD with Nf=2+1 dynamical quark flavours. By using partially twi…
