The phase-shift of isospin-2 pi-pi scattering from lattice QCD
The phase-shift of isospin-2 pi-pi scattering lattice QCD
2011/1/7
Finite-volume lattice QCD calculations offer the possibility of extracting resonance parameters from the energy-dependent elastic phase-shift computed using the Luescher technique. In this letter, as ...
K --> pi pi matrix elements from mixed action lattice QCD
K --> pi pi matrix elements mixed action lattice QCD
2011/1/7
We present a new method for determining K --> pi pi matrix elements from lattice simulations that is less costly than direct simulations of K --> pi pi at physical kinematics. It improves, however, up...

Monte Carlo generator QED radiative corrections Ke4 decay
2010/5/7
PHOTOS Monte Carlo is widely used for simulating QED e ects in decay of intermediate particles
and resonances. It can be easily connected to other main process generators. In this paper we consider d...
