Best-case scenarios for neutrino capture experiments
Kyrylo Bondarenko, Alexey Boyarsky, Josef Pradler +1
A direct discovery of the cosmic neutrino background would bring to a closure the searches for relic left-over radiation predicted by the Hot Big Bang cosmology. Recently, the KATR…
Freezing In Vector Dark Matter Through Magnetic Dipole Interactions
Gordan Krnjaic, Duncan Rocha, Anastasia Sokolenko
We study a simple model of vector dark matter that couples to Standard Model particles via magnetic dipole interactions. In this scenario, the cosmological abundance arises through…
Neutron stars as photon double-lenses: constraining resonant conversion into ALPs
Kyrylo Bondarenko, Alexey Boyarsky, Josef Pradler +1
Axion-photon conversion is a prime mechanism to detect axion-like particles that share a coupling to the photon. We point out that in the vicinity of neutron stars with strong magn…
Direct detection and complementary constraints for sub-GeV dark matter
Kyrylo Bondarenko, Alexey Boyarsky, Torsten Bringmann +3
Traditional direct searches for dark matter, looking for nuclear recoils in deep underground detectors, are challenged by an almost complete loss of sensitivity for light dark matt…
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…
Sensitivity of the SHiP experiment to Heavy Neutral Leptons
SHiP Collaboration
Heavy Neutral Leptons (HNLs) are hypothetical particles predicted by many extensions of the Standard Model. These particles can, among other things, explain the origin of neutrino…
Connection between diphoton and triboson channels in new physics searches
Anastasia Sokolenko, Kyrylo Bondarenko, Alexey Boyarsky +1
Diphoton channel provides a clean signature in searches for new physics. In this paper, we discuss a connection between the diphoton channel () and triboson channels (, $Z…
