متن کاملDifferential decay rate of B → πlν semileptonic decay with lattice NRQCD
We present a lattice QCD calculation of B → πlν semileptonic decay form factors in the small pion recoil momentum region. The calculation is performed on a quenched 163 × 48 lattice at β = 5.9 with the NRQCD action including the full 1/M terms. The form factors f1(v · kπ) and f2(v · kπ) defined in the heavy quark effective theory for which the heavy quark scaling is manifest are adpoted, and we...
متن کاملComputation of the heavy-light decay constant using nonrelativistic lattice QCD.
We report results on a lattice calculation of the heavy-light meson decay constant employing the non-relativistic QCD approach for heavy quark and Wilson action for light quark. Simulations are carried out at β = 6.0 on a 16 × 48 lattice. Signal to noise ratio for the ground state is significantly improved compared to simulations in the static approximation, enabling us to extract the decay con...
متن کاملNucleon Decay Matrix Elements from Lattice QCD
We present a GUT-model-independent calculation of hadron matrix elements for all dimension-six operators associated with baryon number violating processes using lattice QCD. Our results cover all the matrix elements required to estimate the partial lifetimes of (proton,neutron)→(π, K, η) +(ν̄, e, μ) decay modes. We point out the necessity of disentangling two form factors that contribute to the ...
متن کاملNeutrinoless double beta decay from lattice QCD
While the discovery of non-zero neutrino masses is one of the most important accomplishments by physicists in the past century, it is still unknown how and in what form these masses arise. Lepton number-violating neutrinoless double beta decay is a natural consequence of Majorana neutrinos and many BSM theories, and many experimental efforts are involved in the search for these processes. Under...
