We have now enhanced the decay calculation to the next level by a generic ansatz to calculate two-body decay widths at the full one-loop level. These extensions are …
WebNov 5, 2003 · For three-body decay of a nuclear level, it is suggested that instead of the total width being the sum of the partial widths calculated from R-matrix formulas the contributions from different decay channels should be added coherently.Two-proton and two-neutron decay widths are considered, and also widths of levels of Be 9 and B 9.. … WebHence, the decay width is simply the decay rate per particle. The branching ratio, Bi, for a particular decay mode, i, is defined as the percentage of the particles decaying in this …
WebaMC@NLO packages that allows the computation of tree-level decay widths for ar-bitrary new physics models. The module consists of two parts: 1.A FeynRules part, which allows one to compute analytically all tree-level two-body decay rates and to output them in the UFO format. 2.A MadGraph5 aMC@NLO part, which allows the numerical computation of WebNov 2, 2012 · We perform a nonperturbative calculation of the π(0) → γγ transition form factor and the associated decay width using lattice QCD. The amplitude for a two-photon final state, which is not an eigenstate of QCD, is extracted through a Euclidean time integral of the relevant three-point function. We ut …
