摘要:We present preliminary results from the RBC and UKQCD collaborations for the Kl3 form factor
f Kp
0 (0)= f Kp
+ (0) with 2+1 flavours of dynamical domain wall quarks. Simulations are performed
on 163×32×16 and 243×64×16 lattices with three values of the light quark mass, allowing for
an extrapolation to the chiral limi
