Results on the Gluon Propagator in Lattice Covariant Gauges
L. Giusti, M. L. Paciello, S. Petrarca +2
We illustrate preliminary results on the gluon propagator computed in generic covariant lattice gauges in the quenched approximation with the Wilson action. We have applied a recen…
Analysis of the DeltaI=1/2 Rule and e'/e with Overlap Fermions
S. Capitani, L. Giusti
We study the renormalization of the DeltaS=1 effective weak Hamiltonian with overlap fermions. The mixing coefficients among dimension-six operators are computed at one loop in per…
Exact results and approximation schemes for the Schwinger model with the overlap Dirac operator
L. Giusti, C. Hoelbling, C. Rebbi
We propose new techniques to implement numerically the overlap-Dirac operator which exploit the physical properties of the underlying theory to avoid nested algorithms. We test the…
Perturbative Renormalization of Weak-Hamiltonian Four-Fermion Operators with Overlap Fermions
S. Capitani, L. Giusti
The renormalization of the most general dimension-six four-fermion operators without power subtractions is studied at one loop in lattice perturbation theory using overlap fermions…
RI/MOM Renormalization Window and Goldstone Pole Contamination
L. Giusti, A. Vladikas
We perform a comparative study of the ratio of lattice (Wilson fermion) renormalization constants Z_P/Z_S, obtained non-perturbatively from the RI/MOM renormalization conditions an…
Mixing of B mesons and Decay Constants with the Non-Perturbatively Improved Action
D. Becirevic, D. Meloni, A. Retico +4
Several quantities relevant to phenomenological studies of the mixing of neutral B mesons are computed on the lattice. Our main results are: f_{Bd} sqrt(B_{Bd})=206(28)(7) MeV, f_{…
