چکیده

In this work we present a formal solution of the extended version of the Friedrichs Model. The Hamiltonian consists of discrete and continuum bosonic states, which are coupled to fermions. The simultaneous treatment of the couplings of the fermions with the discrete and continuous sectors of the bosonic degrees of freedom leads to a system of coupled equations, whose solutions are found by applying standard methods of representation of bound and resonant states.

The Friedrichs-Model with fermion-boson couplings

In this work we present an extended version of the Friedrichs Model, which includes fermion-boson couplings. The set of fermion bound states is coupled to a boson field with discrete and continuous components. As a result of the coupling some of the fermion states may become resonant states. This feature suggests the existence of a formal link between the occurrence of Gamow Resonant States in ...

Flavor Physics in the Randall-Sundrum Model I. Theoretical Setup and Electroweak Precision Tests

A complete discussion of tree-level flavor-changing effects in the Randall-Sundrum (RS) model with brane-localized Higgs sector and bulk gauge and matter fields is presented. The bulk equations of motion for the gauge and fermion fields, supplemented by boundary conditions taking into account the couplings to the Higgs sector, are solved exactly. For gauge fields the Kaluza-Klein (KK) decomposi...

Abstract We propose an alternative unification scenario where the Higgs self-coupling (λ) is determined by impossing its unification with the electroweak gauge couplings. An attractive feature of models within this scenario is the possibility to determine the Higgs boson mass by evolving λ from the electroweak-Higgs unification scale MGH down to the electroweak scale. The unification condition ...

We discuss the fermion couplings in a four dimensional SU(2) linear moose model by allowing for direct couplings between the left-handed fermions on the boundary and the gauge fields in the internal sites. This is realized by means of a product of non linear σ-model scalar fields which, in the continuum limit, is equivalent to a Wilson line. The effect of these new non local couplings is a cont...

In this paper a scenario admitting the participation of the right-handed vector VR and axial AR couplings with the conservation of the left-handed standard (V, A)L couplings is considered. The research is based on the muon capture by proton. We consider muon capture at the level of the Fermi theory, whose hamiltonian describes the four-fermion point (contact) interaction. Neutrinos are assumed ...
