The K → π vector form factor at zero momentum transfer on the lattice
We present a quenched lattice study of the form factors f + (q 2) and f 0 (q 2) of the matrix elements π|¯ sγ µ u|K. We focus on the second-order SU(3)-breaking quantity [1 − f + (0)], which is necessary to extract |V us | from K ℓ3 decays. For this quantity we show that it is possible to reach the percent precision which is the required one for a significant determination of |V us |. The leadi...

متن کاملElectromagnetic Form Factors at Large Momentum Transfer
Recent improvements of the hard scattering picture for the large p⊥ behaviour of electromagnetic form factors, namely the inclusion of both Sudakov corrections and intrinsic transverse momentum dependence of the hadronic wave function, are reviewed. On account of these improvements the perturbative contributions to the pion’s and the nucleon’s form factor can be calculated in a theoretically se...
متن کاملLattice analysis of semi-leptonic form factors∗
We present preliminary results from simulations done on 170 32×64 lattices at β = 6.0 using quenched Wilson fermions. This talk focuses on the Q behavior of the form-factors, extrapolation in quark masses, dependence on renormalization scheme, and comparison with heavy-quark effective theory (HQET). Even though we cannot estimate errors due to quenching and discretization, our results are consi...
متن کامل2 00 5 Bounds on the slope and the curvature of the scalar Kπ form factor at zero momentum transfer
Bounds on the slope and the curvature of the scalar Kπ form factor at zero momentum transfer Abstract We derive and calculate unitarity bounds on the slope and curvature of the strangeness-changing scalar form factor at zero momentum transfer, using low-energy constraints and Watson final state interaction theorem. The results indicate that the curvature is important and should not be neglected...
