First calculation of K to pi vector form factor with two-flavor dynamical domain-wall quarks on a 16^3x32x12 lattice.

Findings

Good agreement with previous quenched QCD estimates.

Results align with phenomenological models.

Abstract

We report on our calculation of K \to \pi vector form factor by numerical simulations of two-flavor QCD on a 16^3x32x12 lattice at a \simeq 0.12 fm using domain-wall quarks and DBW2 glue. Our preliminary result at a single sea quark mass correponding to m_PS/m_V \simeq 0.53 shows a good agreement with previous estimate in quenched QCD and that from a phenomenological model.
