Description
We investigate the calculation of the matrix element of the electromagnetic
operator between kaon and pion states, using maximally twisted-mass fermions
with two flavors of dynamical quarks. The operator is renormalized
non-perturbatively and our simulations at different values of the lattice
spacing and pion masses are extrapolated to the continuum limit and to the
physical kaon and pion masses.
