N2 - We present the status of on-going calculations of the K → πlv and D→ K(π)lv semileptonic form factors at q2 = 0. These form factors are important for the determination of the CKM matrix elements |Vus| and |Vcs(d) | respectively. This work uses the HISQ action for both valence quarks and sea quarks on MILC Nf = 2+1 + 1 configurations. We employ twisted boundary conditions to calculate the form factors at zero momentum transfer directly. The K → π results are an update to previously published results with new data at the physical point. The D → K(π) results are preliminary.
