Magnetic field driven enhancement of the weak decay width of charged pions
Autor: Maximo Coppola, Daniel Gomez Dumm, Santiago Noguera, Norberto N. Scoccola
Publikováno v: Journal of High Energy Physics, Vol 2020, Iss 9, Pp 1-19 (2020)
Abstract We study the effect of a uniform magnetic field B → $$ \overrightarrow{B} $$ on the decays π − → l − ν ¯ l $$ {\pi}^{-}\to {l}^{-}{\overline{\nu}}_l $$ , where l − = e −, μ −, carrying out a general analysis that includes f

Main features of nonlocal chiral quark models are discussed, focusing on the description of low energy phenomenology and the analysis of phase transitions at finite temperature and/or chemical potential. Applications to compact stars are commented.

Approximate flavor symmetries at a grand unification scale
Autor: Daniel Gomez Dumm
Publikováno v: Scopus-Elsevier
We study the evolution of fermion mass matrices considering the hypothesis of approximate flavor symmetries (AFS) in the Standard Model and a two-Higgs-doublet model. We find that the hierarchical structure is not significantly altered by the running

Strong-Interaction Matter under Extreme Conditions from Chiral Quark Models with Nonlocal Separable Interactions
Autor: Daniel Gómez Dumm, Juan Pablo Carlomagno, Norberto N. Scoccola
Publikováno v: Symmetry, Vol 13, Iss 1, p 121 (2021)
We review the current status of the research on effective nonlocal NJL-like chiral quark models with separable interactions, focusing on the application of this approach to the description of the properties of hadronic and quark matter under extreme

Electric and weak electric dipole form factors for heavy fermions in a general two Higgs doublet model
Autor: Daniel Gomez Dumm, González-Sprinberg, G. A.
Publikováno v: Scopus-Elsevier
The electric and weak electric dipole form factors for heavy fermions are calculated in the context of the most general two-Higgs-doublet model (2HDM). We find that the large top mass can produce a significant enhancement of the electric dipole form
