Abstract: Supersymmetric Grand Unification scenarios with non-universal gaugino masses have been widely investigated in the context of the SU(5) and SO(10) gauge groups. Here, we take a less conventional approach, and revisit a class of orbifold models with non-universal gauginos, developed by Brignole, Ibáñez and Muñoz.
Abstract: I will discuss models of supersymmetric grand unification based on the gauge group SU(5). We consider models with non-universal gaugino masses and confront them with low energy constraints, including the Higgs boson mass and the Dark Matter relic density.
The Physics Nobel Prize 2013 was awarded to F. Englert and P. Higgs, "for the theoretical discovery of a mechanics that contributes to our understanding of the origin of mass of subatomic particles". A great day for particle physics! Read here an account by Gr@v researchers.
Charybdis++ is a new version of the Charybdis2, a black hole event generator that models the production and evaporation of black holes in high energy hadronic collisions according to the ADD model.
Abstract: The collision of two gravitationally interacting, ultra-relativistic, extended sources is being examined. This investigation classifies the transverse distributions that are collided according to whether one or two (a small and a large) apparent horizons may or may not be formed in a flat background in 4 dimensions.
Abstract: I will report on how some versions of the 2-Higgs doublet model (2HDM) are doing when confronted with the LHC data. I will also discuss some interesting limits of 2HDMs and in particular the case of degenerate scalars. Finally I will discuss how the LHC results help us to sleep safe at night.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
