LHC signatures of WIMP-triggered baryogenesis

Higgs Boson Signatures of MSSM Electroweak Baryogenesis

Electroweak baryogenesis (EWBG) in the MSSM can account for the cosmological baryon asymmetry, but only within a restricted region of the parameter space. In particular, MSSM EWBG requires a mostly right-handed stop that is lighter than the top quark and a standard model-like light Higgs boson. In the present work we investigate the effects of the light stop on Higgs boson production and decay....

Impact of a CP Violating Higgs: from LHC to Baryogenesis

We observe a generic connection between LHC Higgs data and electroweak baryogenesis: the particle that contributes to CP violating hgg or hγγ vertex would provide a CP violating source during first order phase transition. It is illustrated in the 2HDM that a common CP violating phase controls the lightest Higgs properties at the LHC, electric dipole moments and the CP violating source for elect...

Direct detection of baryogenesis mechanism from squark decays at LHC

We investigate the feasibility of directly detecting a generation mechanism of the cosmic baryon asymmetry by repeating the same particle physics process inside the LHC. We propose a framework with R-parity and CP violating squark decays responsible for baryogenesis, which can be embedded in supersymmetric models and is partly motivated by naturalness. We argue that the baryon number generation...

LHC Signatures Of Scalar Dark Energy

Signatures of black holes at the LHC

Signatures of black hole events at CERN’s Large Hadron Collider are discussed. Event simulations are carried out with the Fortran Monte Carlo generator CATFISH. Inelasticity effects, exact field emissivities, color and charge conservation, corrections to semiclassical black hole evaporation, gravitational energy loss at formation and possibility of a black hole remnant are included in the analy...
