Constraints from the CHARM experiment on Heavy Neutral Leptons with tau mixing
Iryna Boiarska, Alexey Boyarsky, Oleksii Mikulenko +1
We re-analyze the results of the searches for Heavy Neutral Leptons (HNLs) by the CHARM experiment. We study HNL decay channel and show that, in addi…
Light scalar production from Higgs bosons and FASER 2
Iryna Boiarska, Kyrylo Bondarenko, Alexey Boyarsky +3
The most general renormalizable interaction between the Higgs sector and a new gauge-singlet scalar is governed by two interaction terms: cubic and quartic. The quartic interac…
Phenomenology of GeV-scale scalar portal
Iryna Boiarska, Kyrylo Bondarenko, Alexey Boyarsky +3
We review and revise the phenomenology of the scalar portal -- a new scalar particle with the mass in GeV range that mixes with the Higgs boson. In particular, we consider producti…
Probing baryon asymmetry of the Universe at LHC and SHiP
Iryna Boiarska, Kyrylo Bondarenko, Alexey Boyarsky +4
The origin of the baryon asymmetry of the Universe (BAU) is one of the major puzzles beyond the Standard Model. Detecting the particles responsible for the generation of the BAU wo…
