One Loop Renormalization of Fermilab Fermions
The series here is an expansion in the dimensionality of the various operators. Each of these terms comes with a new coupling constant cn. In order to use this type of action we must do two things, we must truncate the series at some specified order in n and we must calculate the new couplings somehow. Fixing the new couplings can be done in a number of ways, for example, the first step could b...
متن کاملOne-loop renormalization group equations of the neutrino mass matrix in the triplet seesaw model
Within the framework of the standard model plus one heavy Higgs triplet, we derive a full set of one-loop renormalization group equations of the neutrino mass matrix and Higgs couplings in both full and effective theories. The explicit RGEs of neutrino masses, flavor mixing angles and CP-violating phases are also obtained, and their non-trivial running behaviors around the Higgs triplet mass th...
متن کاملMssm Higgs Sector at the One-loop Level
This work provides an elementary introduction to the Higgs sector renormalisation within the Minimal Suppersymmetric Standard Model (MSSM) framework. The main aim of the paper is to clarify some technical details that are usually omitted in the existing literature. The MSSM tree-level relation m 2 h + m 2 H = m 2 A + m 2 Z is renormalised using the standard technique of direct computation of th...
متن کاملTwo loop divergences studied with one loop Constrained Differential Renormalization
In the context of Differential Renormalization, using Constrained Differential Renormalization rules at one loop, we show how to obtain concrete results in two loop calculations without making use of Ward identities. In order to do that, we obtain a list of integrals with overlapping divergences compatible with CDR that can be applied to various two loop background field calculations. As an exa...
متن کاملOne-loop Renormalization of the Qcd Schrr Odinger Functional
In a previous publication, we have constructed the Schrr odinger functional in Wil-son's lattice QCD. It was found that the naive continuum limit leads to a well-deened classical continuum theory. Starting from the latter, a formal continuum deenition of the Schrr odinger functional is given and its saddle point expansion is carried out to one-loop order of perturbation theory. Dimensional regu...
