Renormalization of HQET operators: O() improvement and matching with QCD
M. Papinutto, G. Herdoiza, C. Pena +1
We determine a basis of dimension-7 operators which arise at O() in the Symanzik expansion of the operators with static heavy quarks. We consider both Wilson-like and Gin…
Testing chiral effective theory with quenched lattice QCD
L. Giusti, P. Hernandez, S. Necco +3
We investigate two-point correlation functions of left-handed currents computed in quenched lattice QCD with the Neuberger-Dirac operator. We consider two lattice spacings a~0.09,0…
Non-perturbative renormalisation of four-fermion operators in N_f=2 QCD
P. Dimopoulos, G. Herdoiza, F. Palombi +4
We present results for the non-perturbative renormalisation of four-fermion operators with two flavours of dynamical quarks. We consider both fully relativistic left current-left c…
First quenched results for the matrix elements of the B_{B_s} mixing parameter in the static limit from tmQCD
F. Palombi, M. Papinutto, C. Pena +1
We report on a non-perturbative study of the scale-dependent renormalization factors of a multiplicatively renormalizable basis of Delta B=2 parity-odd four-fermion operators in qu…
Non-perturbative renormalization of static-light four-fermion operators in quenched lattice QCD
Filippo Palombi, Mauro Papinutto, Carlos Pena +1
We perform a non-perturbative study of the scale-dependent renormalization factors of a multiplicatively renormalizable basis of parity-odd four-fermion operators in quenc…
Flavour symmetry restoration and kaon weak matrix elements in quenched twisted mass QCD
P. Dimopoulos, J. Heitger, F. Palombi +3
We simulate two variants of quenched twisted mass QCD (tmQCD), with degenerate Wilson quarks of masses equal to or heavier than half the strange quark mass. We use Ward identities…
