A bstractWe present a new calculation of the K → π semileptonic form factor at zero momentum transfer in domain wall lattice QCD with Nf = 2+1 dynamical quark flavours. By using partially twisted boundary conditions we simulate directly at the phenomenologically relevant point of zero momentum transfer. We perform a joint analysis for all available ensembles which include three different lattice spacings (a = 0.09 – 0.14 fm), large physical volumes (mπL > 3.9) and pion masses as low as 171 MeV… Expand
