WebThe exclusive decay of B + → J / ψ ρ + is studied in the framework of the QCD factorization (QCDF) method and final state interaction (FSI). A direct B + → J / ψ ρ + decay is only … WebFeynman diagram for the same process as in the animation, with the individual quark constituents shown, ... The suppression of the electronic decay mode with respect to the muonic one is given approximately (up to a few percent effect of the radiative corrections) by the ratio of the half-widths of the pion–electron and the pion–muon decay ...
WebJul 5, 2016 · Feynman diagrams look to be pictures of processes that happen in space and time, and in a sense they are, but they should not be interpreted too literally. What they show are not rigid geometric trajectories, but more flexible, “topological” constructions, reflecting quantum uncertainty. WebThe corresponding Feynman diagram will be: This is a weak decay of the strange quark. It is an allowed diagonal change between quark generations. The Feynman diagram for the s to u transition is a combination of two quark-W vertices. The pion is derived from a same generation quark weak vertex. Return to top of page
