The appearance of non trivial torsion for some Ricci dependent theories in the Palatini formalism
Juliana Osorio Morales, Osvaldo Santillán
As is known from studies of gravity models in the Palatini formalism, there exist two inequivalent definitions of the generalized Ricci tensor in terms of the generalized curvature…

Some comments about emission channels of non abelian vortices
Osvaldo P. Santillán
As is well established, several gauge theories admit vortices whose mean life time is very large. In some cases, this stability is a consequence of the topology of the symmetry gro…

Neutrino emission and initial evolution of axionic quark nuggets
O. Santillán, A. Morano
The axion quark nuggets introduced in \cite{zhitnitsky}-\cite{zhitnitsky13} are a candidate for cold dark matter which, in addition, may be relevant in baryogenesis scenarios. The…
