Light neutrino masses from gravitational condensation: the Schwinger–Dyson approach

In this work we demonstrate that non-zero neutrino masses can be generated from gravitational interactions. We solve the Schwinger–Dyson equations to find a non-trivial vacuum thereby determining the neutrino condensate scale and the number of new particle degrees of freedom required for gravitationally induced dynamical chiral symmetry breaking. We show for minimal beyond the Standard Model particle content, the scale of the condensation occurs close to the Planck scale.

Electroweak Baryogenesis with Anomalous Higgs Couplings

In non-linear realisation of the electroweak gauge symmetry, the LHC Higgs boson can be assumed to be a singlet under [Formula: see text]. In such scenario, the Standard Model particle content can be kept but new sets of couplings are allowed. We identify a range of anomalous Higgs cubic and the [Formula: see text]-violating Higgs-top quark couplings that leads to first order phase transition and successful baryogenesis at the electroweak scale.

NUCLEAR PHYSICS IN A SUSY UNIVERSE

We refine a previous zeroth-order analysis of the nuclear properties of a supersymmetric (SUSY) universe with standard model particle content plus degenerate SUSY partners. No assumptions are made concerning the Higgs structure except we assume that the degenerate fermion/sfermion masses are nonzero. This alternate universe has been dubbed Susyria and it has been proposed that such a world may exist with zero vacuum energy in the string landscape.
