One-loop matching conditions in neutrino effective theory
نویسندگان
چکیده
We investigate matching conditions and threshold corrections between full effective theories based on the type I seesaw mechanism. In general, using an intuitive Feynman diagrammatical approach, we compute amplitudes before after integrating out heavy right-handed neutrinos at scale. particular, derive one-loop theories. The of parameters are influenced by to corresponding vertices as well wave function for Higgs lepton fields. Our results comparable earlier a functional approach.

One-loop Effective Action in Open-string Theory
This is a summary of the analysis of the one-loop effective action in Z2-orbifold compactifications of type-I theory presented in references [1,2]. We show how, for non-abelian group factors, the threshold effects are ultraviolet finite though given entirely by a six-dimensional field theory expression. We also discuss implications for the equivalence between Type-I and Heterotic four dimension...
متن کاملOne loop scalar functions in the heavy quark effective theory
Since its early applications [1] the heavy quark symmetry has been one of the key ingredients in the theoretical investigations of hadrons containing a heavy quark. It has been successfully applied to the heavy hadrons spectroscopy, to the inclusive as well as to a number of exclusive decays (for reviews of the heavy quark effective theory and related issues see [2] or [3]). To describe interac...
متن کاملOne-loop effective brane action
The one-loop effective action for a p brane embedded in a D = p+2 Minkowski spacetime in the static gauge is calculated. Rescaling the quantum fluctuation by −g0 evaluated on the background brane leads to the one-loop effective action expressed only in terms of infrared and ultraviolet divergent geometric scalars. After the infrared divergences are absorbed into the quantum fluctuation, there r...
متن کاملOne-Loop Effective Action in Orbifold Compactifications
We employ the covariant background formalism to derive generic expressions for the one-loop effective action in field theoretic orbifold compactifications. The contribution of each orbifold sector is given by the effective action of its fixed torus with a shifted mass matrix. We thus study in detail the computation of the heat kernel on tori. Our formalism manifestly separates UV sensitive (loc...
متن کاملBounding Effective Operators at the One-Loop Level: The Case of Four-Fermion Neutrino Interactions
The contributions of non-standard four-neutrino contact interactions to electroweak observables are considered at the one-loop level by using the effective quantum field theory. The analysis is done in terms of three unknown parameters: the strength of the non-standard neutrino interactions, F̃ , an additional derivative coupling needed to renormalize the divergent contributions that appear when...
