Witten's loop in the flipped SU(5) unification

Michal Malinský, Carolina Arbeláez Rodríguez, Helena Kolešová

We study a very simple, yet potentially realistic renormalizable flipped SU(5) scenario in which the right-handed neutrino masses are generated at very high energies by means of a…

Witten's mechanism in the flipped SU(5) unification

Carolina Arbeláez, Helena Kolešová, Michal Malinský

We argue that the Witten's loop mechanism for the right-handed Majorana neutrino mass generation identified originally in the SO(10) grand unification context can be successfully a…

On baryogenesis from dark matter annihilation

Nicolas Bernal, Stefano Colucci, Francois-Xavier Josse-Michaux +2

We study in detail the conditions to generate the baryon asymmetry of the universe from the annihilation of dark matter. This scenario requires a low energy mechanism for thermal b…

Matrix model for deconfinement in an SU(2) gauge theory in 2+1 dimensions

Pedro Bicudo, Robert D. Pisarski, Elina Seel

We use matrix models to characterize deconfinement at a nonzero temperature T for an SU(2) gauge theory in three spacetime dimensions. At one loop order, the potential for a consta…

Neutrino mixing with revamped A4 flavour symmetry

S. Morisi, D. V. Forero, J. C. Romao +1

We suggest a minimal extension of the simplest A4 flavour model that can induce a nonzero theta13 value, as required by recent neutrino oscillation data from reactors and accelerat…

Five models for lepton mixing

P. M. Ferreira, L. Lavoura, P. O. Ludl

We produce five flavour models for the lepton sector. All five models fit perfectly well---at the one-sigma level---the existing data on the neutrino mass-squared differences and o…

Neutrino masses and mixing in A4 models with three Higgs doublets

R. Gonzalez Felipe, H. Serodio, Joao P. Silva

We study neutrino masses and mixing in the context of flavor models with A4 symmetry, three scalar doublets in the triplet representation, and three lepton families. We show that t…

Models with three Higgs doublets in the triplet representations of A4 or S4

R. Gonzalez Felipe, H. Serodio, Joao P. Silva

We consider the quark sector of theories containing three scalar SU(2)_L doublets in the triplet representation of A4 (or of S4) and three generations of quarks in arbitrary A4 (or…

Octet to decuplet electromagnetic transition in a relativistic quark model

G. Ramalho, K. Tsushima

We study the octet to decuplet baryon electromagnetic transitions using the covariant spectator quark model, and predict the transition magnetic dipole form factors for those invol…

Extended evolution equations for neutrino propagation in astrophysical and cosmological environments

Cristina Volpe, Daavid Väänänen, Catalina Espinoza

We derive the evolution equations for a system of neutrinos interacting among themselves and with a matter background, based upon the Bogoliubov-Born-Green-Kirkwood-Yvon (BBGKY) hi…

Flavoured CP asymmetries for type II seesaw leptogenesis

R. Gonzalez Felipe, F. R. Joaquim, H. Serodio

A novel contribution to the leptonic CP asymmetries in type II seesaw leptogenesis scenarios is obtained for the cases in which flavor effects are relevant for the dynamics of lept…
