K ?? form factor with Nf = 2+1 dynamical domain wall fermions

K ?? form factor with Nf = 2+1 dynamical domain wall fermions
K ?? form factor with Nf = 2+1 dynamical domain wall fermions
We present the latest results from the UKQCD/RBC collaborations for the Kl3 form factor with
2+1 avours of dynamical domain wall quarks. Simulations are performed on 1633216 and
243 6416 lattices with three values of the light quark mass, allowing for an extrapolation to
the chiral limit. After interpolating to zero momentum transfer, we obtain the preliminary result
f Kp
+ (0) = 0:9680(16), which is in excellent agreement with an earlier Nf = 2 result

Abstract

We present the latest results from the UKQCD/RBC collaborations for the Kl3 form factor with
2+1 avours of dynamical domain wall quarks. Simulations are performed on 1633216 and
243 6416 lattices with three values of the light quark mass, allowing for an extrapolation to
the chiral limit. After interpolating to zero momentum transfer, we obtain the preliminary result
f Kp
+ (0) = 0:9680(16), which is in excellent agreement with an earlier Nf = 2 result
