The variation of the electromagnetic coupling and quintessence
M. C. Bento, R. Gonzalez Felipe
The properties of quintessence are examined through the study of the variation of the electromagnetic coupling. We consider two simple quintessence models with a modified exponenti…
Iterative method to compute the Fermat points and Fermat distances of multiquarks
P. Bicudo, M. Cardoso
The multiquark confining potential is proportional to the total distance of the fundamental strings linking the quarks and antiquarks. We address the computation of the total strin…
Stability window and mass-radius relation for magnetized strange quark stars
R. Gonzalez Felipe, A. Perez Martinez
The stability of magnetized strange quark matter (MSQM) is investigated within the phenomenological MIT bag model, taking into account the variation of the relevant input parameter…
Quasi-degenerate neutrinos and tri-bi-maximal mixing
Ivo de Medeiros Varzielas, Graham G. Ross, Mario Serna
We consider how, for quasi-degenerate neutrinos with tri-bi-maximal mixing at a high-energy scale, the mixing angles are affected by radiative running from high to low-energy scale…
Discrete and continuous symmetries in multi-Higgs-doublet models
P. M. Ferreira, Joao P. Silva
We consider the Higgs sector of multi-Higgs-doublet models in the presence of simple symmetries relating the various fields. We construct basis invariant observables which may in p…
Building the full PMNS Matrix from six independent Majorana-type phases
Gustavo C. Branco, M. N. Rebelo
In the framework of three light Majorana neutrinos, we show how to reconstruct, through the use of 3 x 3 unitarity, the full PMNS matrix from six independent Majorana-type phases.…
Three-flavour neutrino oscillation update
Thomas Schwetz, Mariam Tortola, Jose W. F. Valle
We review the present status of three-flavour neutrino oscillations, taking into account the latest available neutrino oscillation data presented at the Neutrino 2008 Conference. T…
Solving the Bethe-Salpeter equation for a pseudoscalar meson in Minkowski space
V. Sauli
A new method of solution of the Bethe-Salpeter equation for a pseudoscalar quark-antiquark bound state is proposed. With the help of an integral representation, the results are dir…
