Renormalization group evolution of R-parity-violating Yukawa couplings.

We study the evolution of R-parity-violating (RPV) couplings in the minimum supersymmetric standard model, between the electroweak and grand unification scales, assuming a family hierarchy for these coupling strengths. Particular attention is given to solutions where both the R-conserving and R-violating top quark Yukawa couplings simultaneously approach infrared fixed points; these we analyse ...

R-parity-Violating Supersymmetric Yukawa Couplings: A Mini-review

I review the bounds on the R-parity-violating supersymmetric Yukawa couplings from the considerations of proton stability, n–n̄ oscillation, νe-Majorana mass, neutrino-less double β decay, charged-current universality, e–μ–τ universality, νμ–e scattering, atomic parity violation, νμ deep-inelastic scattering, K -decays, τ -decays, Ddecays and from the precision LEP electroweak observables. I als...

the evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...

Higgs-dependent Yukawa couplings

We consider the possibility that the Yukawa couplings depend on the Higgs field, with the motivation of generating the fermion mass hierarchy through appropriate powers of the Higgs vacuum expectation value. This leads to drastic modifications of the Higgs branching ratios, new Higgs contributions to various flavor-violating processes, and observable rates for the top quark decay t → hc. The un...

Heterotic Yukawa couplings and continuous Wilson lines

Realistic heterotic string models require the presence of the Wilson lines. We study the effect of continuous Wilson lines on the heterotic Yukawa couplings and find that the presence of continuous Wilson lines affects the magnitude of the twisted Yukawa couplings resulting in their stronger hierarchy.
