Constraints on the parameters of the neutrino extension of the Standard Model
Volodymyr Gorkavenko, Oleksandr Khasai, Oleg Ruchayskiy +1
Heavy neutral leptons (HNLs) are hypothetical particles proposed as a potential explanation for neutrino oscillations and the generation of the baryon asymmetry in the Universe. Th…
LHCb potential to discover long-lived new physics particles with lifetimes above 100 ps
Volodymyr Gorkavenko, Brij Jashal, Valerii Kholoimov +6
For years, it has been believed that the main LHC detectors can only restrictively play the role of a lifetime frontier experiment exploring the parameter space of long-lived parti…
Production of Chern-Simons bosons in decays of mesons
Yuliia Borysenkova, Pavlo Kashko, Mariia Tsarenkova +2
We consider the effective interaction of quarks with a new GeV-scale vector particle that couples to electroweak gauge bosons by the so-called effective Chern-Simons interaction. W…
Production of GeV-scale heavy neutral leptons in 3-body decays. Comparison with the PYTHIA approach
Volodymyr M. Gorkavenko, Yuliia R. Borysenkova, Mariia S. Tsarenkova
Despite the undeniable success of the Standard Model of particle physics (SM), there are some phenomena that the SM can't explain. These phenomena indicate that the SM has to be mo…
Search for hidden particles in intensity frontier experiment SHiP
Volodymyr M. Gorkavenko
Despite the undeniable success of the Standard Model of particle physics (SM) there are some phenomena (neutrino oscillations, baryon asymmetry of the Universe, dark matter, etc.)…
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…
