WebNo clear signals for η c (2S) production are found in these decay modes. We have also studied resonant structures in charmonium decays to two-body intermediate meson resonances. We report the products of the two-photon decay width and the branching fractions, ΓγB, for each of the charmonium decay modes. WebJan 12, 2024 · In this paper, we have investigated the two-body decay of the top quark (), where q represents one of the quarks d, s and b, in the presence of a monochromatic circularly polarized laser field. Using the lowest-order Dirac-Volkov formalism, we have analytically established the expression for the laser-assisted total decay width of the top …
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 … WebJan 8, 2024 · so 68% of the decay modes are hadronic. That means that the quark antiquark pairs dress themselves up into several hadrons, which are themselves unstable, so they, in turn, decay to many particles. These multi particle decays are included in the 2-body primary decays. A higher-order fundamental vertex, such as WWγ, where the off-shell W would ...
