Rare K decays in a model of quark and lepton masses
نویسندگان
چکیده
An extension of a model of neutrino masses to the quark sector provides an interesting link between these two sectors. A parameter which is important to describe neutrino oscillations and masses is found to be a crucial one appearing in various “penguin” operators, in particular the so-called Z penguin. This parameter is severely constrained by the rare decay processKL → μ+μ−. This in turn has interesting implications on the decay rates of other rare processes such as KL → μe, etc..., as well as on the masses of the neutrinos and the masses of the vector-like quarks and leptons which appear in our model. 12.15.Ff, 12.60.Cn, 13.20.Eb, 14.60.Pq, 14.60.St, 14.70.Pw Typeset using REVTEX 1

Quark-lepton unification and rare meson decays.
We study meson decays mediated by the heavy gauge bosons of the Pati-Salam model of quark-lepton unification. We consider the scenarios in which the τ lepton is associated with the third, second, and first generation of quarks. The most sensitive probes, depending on the scenario, are rare K, π, and B decays.
متن کاملThe role of electroweak penguin and magnetic dipole QCD penguin on hadronic b Quark Decays
This research, works with the effective Hamiltonian and the quark model. Using, the decay rates of matter-antimatter of b quark was investigated. We described the effective Hamiltonian theory which was applied to the calculation of current-current (Q1,2), QCD penguin (Q3,…,6), magnetic dipole (Q8) and electroweak penguin (Q7,…,10) decay rates. The gluonic penguin structure of hadronic decays ...

متن کاملFlavor Physics with light quarks and leptons
The impact of rare K decays and lepton-flavor violating processes in shedding light on physics beyond the Standard Model is reviewd. To this purpose, I first recall the formulation of the Minimal Flavor Violation hypothesis –both in the quark and in the lepton sector– and then use it as guiding principle in comparing the new-physics sensitivity of different rare processes. On the phenomenologic...
متن کاملProbing lepton-number/flavour-violation in semileptonic τ decays into two mesons
The evaluation, systematic analysis and numerical study of the semileptonic τ -lepton decays with two mesons in the final state has been made in the frame of the standard model extended by right handed neutrinos. In the analysis, heavy-neutrino nondecoupling effects, finite quark masses, quark and meson mixings, finite widths of vector mesons, chiral symmetry breakings in vector-meson–pseudosca...
