Dark matter from the scalar sector of 3-3-1 models without exotic electric charges
Simonetta Filippi, William A. Ponce, Luis A. Sanchez
We show that three SU(2) singlet neutral scalars (two CP-even and one CP-odd) in the spectrum of models based on the gauge symmetry SU(3)_c X SU(3)_L X U(1)_X, which do not contain…

Using FEMLAB for Gravitational problems: numerical simulations for all
Christian Cherubini, Simonetta Filippi
We discuss the possibility to solve Modern Numerical Relativity problems using finite element methods (FEM). Adopting a "user friendly" software for handling totally general system…
