CKM matrix elements from tree-level decays and b-hadron lifetimes
Laurent Lellouch
We give an updated summary of the topics covered in Working Group I of the 2nd Workshop on the CKM Unitarity Triangle, with emphasis on the results obtained since the 1st CKM Works…
Preliminary results from a simulation of quenched QCD with overlap fermions on a large lattice
Federico Berruto, Nicolas Garron, Christian Hoelbling +3
We simulate quenched QCD with the overlap Dirac operator. We work with the Wilson gauge action at beta=6 on an 18^3x64 lattice. We calculate quark propagators for a single source p…
Vector and Axial-Vector Propagators in the ε-Regime of QCD
P. H. Damgaard, P. Hernandez, K. Jansen +2
Using quenched and unquenched chiral perturbation theory we compute vector and axial current two-point functions at finite volume and fixed gauge field topology, in the so-called ε…
B_K from quenched QCD with exact chiral symmetry
Nicolas Garron, Leonardo Giusti, Christian Hoelbling +2
We present a calculation of the standard model ΔS=2 matrix element relevant to indirect CP violation in K->ππdecays which uses Neuberger's chiral formulation of lattice fermions. T…
