Beyond the Standard Model
Abstract: The existence of the Higgs mechanism and the associated scalar particle has been firmly established by LHC experiments. While the Standard Model (SM) of elementary particle interactions provides an excellent parametrisation of LHC data, the need for physics beyond SM remains as serious as ever: for example the origin of the weak scale and fermion masses, the dark matter abundance and the matter-antimatter asymmetry remain unexplained. Aspects of these issues are discussed in this talk with concrete and testable model examples.

The dark side of Stars
Abstract: I will talk about how compact stars such as white dwarfs and neutron stars can impose constraints on properties of dark matter models. Dark matter accumulation into neutron stars can change the thermal evolution of the star due to dark matter annihilation taking place inside the star. In the case of asymmetric dark matter, WIMP accumulation might lead under certain conditions to the formation of a black hole that can potentially destroy the star, thus imposing constraints on several models of dark matter.

ADM analysis of massive and bimetric gravity models and the problem of ghosts.
Abstract: We review the ADM analysis of massive gravity and bigravity models, with emphasis on avoidance of Boulware-Deser-ghost-like excitations. The models of dRGT type and a version of bimetric variational principle are discussed in detail. Multimetric models and vielbein formalism are also mentioned.
