Symmetries and Mass Degeneracies in the Scalar Sector

Howard E. Haber, O. M. Ogreid, P. Osland +1

We explore some aspects of models with two and three SU(2) scalar doublets that lead to mass degeneracies among some of the physical scalars. In Higgs sectors with two scalar doubl…

Vacuum Induced CP Violation Generating a Complex CKM Matrix with Controlled Scalar FCNC

Miguel Nebot, Francisco J. Botella, Gustavo C. Branco

We propose a viable minimal model with spontaneous CP violation in the framework of a Two Higgs Doublet Model. The model is based on a generalised Branco-Grimus-Lavoura model with…

Infrared sensitivity of single jet inclusive production at hadron colliders

James Currie, Aude Gehrmann-De Ridder, Thomas Gehrmann +3

Jet production at hadron colliders is a benchmark process to probe the dynamics of the strong interaction and the structure of the colliding hadrons. One of the most basic jet prod…

Solving a Fine-Tuning Problem of the Standard Model through the Introduction of Vector-Like Quarks

F. J. Botella, G. C. Branco, M. Nebot +2

We emphasise that even in the extreme chiral limit where only the top and bottom quarks acquire mass, quark mixing is physically meaningful. This implies that the natural value of…

Constituent-quark model with pionic contributions: electromagnetic transition

Ju-Hyun Jung, Wolfgang Schweiger, Elmar P. Biernat

We report on ongoing work to determine the pion-cloud contribution to the electromagnetic transition form factors. The starting point is an spin-flavor symm…

Symmetry Constrained Two Higgs Doublet Models

Joao M. Alves, Francisco J. Botella, Gustavo C. Branco +3

We study Two-Higgs-Doublet Models (2HDM) where Abelian symmetries have been introduced, leading to a drastic reduction in the number of free parameters in the 2HDM. Our analysis is…

Flavour Conservation in Two Higgs Doublet Models

Francisco J. Botella, Fernando Cornet-Gomez, Miguel Nebot

In extensions of the Standard Model with two Higgs doublets, flavour changing Yukawa couplings of the neutral scalars may be present at tree level. In this work we consider the mos…

Quark mass functions and pion structure in the Covariant Spectator Theory

E. P. Biernat, F. Gross, M. T. Peña +2

The Covariant Spectator Theory is applied to the description of quarks and the pion. The dressed quark mass function is calculated dynamically in Minkowski space and used in the ca…
