Abstract We present the first quenched lattice QCD study of the form factors relevant for the hyperon semileptonic decay Σ − → n l ν . The momentum dependence of both axial and vector form factors is investigated and the values of all the form factors at zero-momentum transfer are presented. Following the same strategy already applied to the decay K 0 → π − l ν , the SU ( 3 ) -breaking corrections to the vector form factor at zero-momentum transfer, f 1 ( 0 ) , are determined with great… CONTINUE READING
