3D matter power spectrum correspondence to 1D Lyman-alpha flux power spectrum
Ivan Ridkokasha, Andres Aramburo-Garcia, Kyrylo Bondarenko +3
The 3D distribution of matter at small scales encodes valuable information about the nature of dark matter and other fundamental physics. A prominent probe of such scales outside g…
Reconstruction of 400 GeV/c proton interactions with the SHiP-charm project
SHiP Collaboration
The SHiP-charm project was proposed to measure the associated charm production induced by 400 GeV/c protons in a thick target, including the contribution from cascade production. A…
Dark photon constraints from CMB temperature anisotropies
Andres Aramburo-Garcia, Kyrylo Bondarenko, Alexey Boyarsky +6
The resonant conversion, within the inter-galactic medium, of regular photons into dark photons amplifies the anisotropy observed in the CMB, thereby imposing stringent constraints…
Probing intergalactic intergalactic magnetic fields with LOFAR LoTSS DR2 data
Kyrylo Bondarenko, Alexey Boyarsky, Anastasia Sokolenko +1
We use Faraday rotation measurements from the latest catalog LoTSS DR2 from LOFAR to probe intergalactic magnetic fields. To identify the extragalactic component of the observed ro…
Unveiling new physics with discoveries at Intensity Frontier
Oleksii Mikulenko, Kyrylo Bondarenko, Alexey Boyarsky +1
The idea of feebly interacting particles (FIPs) has emerged as an important approach to address challenges beyond the Standard Model. The next generation of Intensity Frontier expe…
New physics at the Intensity Frontier: how much can we learn and how?
Oleksii Mikulenko, Kyrylo Bondarenko, Alexey Boyarsky +1
Intensity Frontier experiments are often evaluated by the smallest coupling it can probe, irrespective of what particle can be found or the scientific significance of its detection…
Sensitivities to feebly interacting particles: public and unified calculations
Maksym Ovchynnikov, Jean-Loup Tastet, Oleksii Mikulenko +1
The increasing interest in Long-Lived Particles (LLPs) has led to numerous proposed experiments in order to search for them. However, the sensitivity estimates published by these e…
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…
Sensitivities to feebly interacting particles: public and unified calculations
Maksym Ovchynnikov, Jean-Loup Tastet, Oleksii Mikulenko +1
The idea that new physics could take the form of feebly interacting particles (FIPs) - particles with a mass below the electroweak scale, but which may have evaded detection due to…
Towards the optimal beam dump experiment to search for feebly interacting particles
Kyrylo Bondarenko, Alexey Boyarsky, Oleksii Mikulenko +2
Future searches for new physics beyond the Standard Model are without doubt in need of a diverse approach and experiments with complementary sensitivities to different types of cla…
Sensitivity of the FACET experiment to Heavy Neutral Leptons and Dark Scalars
Maksym Ovchynnikov, Viktor Kryshtal, Kyrylo Bondarenko
We analyze the potential of the recently proposed experiment FACET (Forward-Aperture CMS ExTension) to search for new physics. As an example, we consider the models of Higgs-like s…
The contribution of magnetized galactic outflows to extragalactic Faraday rotation
Andres Aramburo-Garcia, Kyrylo Bondarenko, Alexey Boyarsky +3
Galactic outflows driven by star formation and active galactic nuclei blow bubbles into their local environments, causing galactic magnetic fields to be carried into intergalactic…

Andres Aramburo-Garcia, Kyrylo Bondarenko, Alexey Boyarsky +3
Previously derived Faraday rotation constraints on the volume-filling intergalactic magnetic field (IGMF) have used analytic models that made a range of simplifying assumptions abo…
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…
