Dark Matter and Electroweak Baryogenesis with Spontaneous Violation in the Early Universe
Subhojit Roy
Dark matter (DM) and the baryon asymmetry of the universe (BAU) are among the most compelling indications of physics beyond the Standard Model. We revisit the inelastic Higgs-porta…
Shedding Light on Dark Matter at the LHC with Machine Learning
Ernesto Arganda, Martín de los Rios, Andres D. Perez +3
We investigate a WIMP dark matter (DM) candidate in the form of a singlino-dominated lightest supersymmetric particle (LSP) within the -symmetric Next-to-Minimal Supersymmetri…
R-parity violation and 8 TeV four-jet events at the LHC
Pedro Bittar, Subhojit Roy, Carlos E. M. Wagner
The CMS Collaboration at the Large Hadron Collider (LHC) has observed two four-jet events with a total invariant mass of about 8 TeV; within each event, the jets can be paired into…
Gamma-Rays and Gravitational Waves from Inelastic Higgs Portal Dark Matter
Dan Hooper, Gordan Krnjaic, Duncan Rocha +1
We explore a simple and predictive dark matter scenario involving a complex scalar field, , coupled to the Higgs portal with no additional field content. In the UV, the field po…
Self Consistent Thermal Resummation: A Case Study of the Phase Transition in 2HDM
Pedro Bittar, Subhojit Roy, Carlos E. M. Wagner
An accurate description of the scalar potential at finite temperature is crucial for studying cosmological first-order phase transitions (FOPT) in the early Universe. At finite tem…
