Neutrino Direct Simulation Monte Carlo: Accurate modeling of out-of-equilibrium decaying cosmological relics
Kensuke Akita, Miguel Escudero, Oleksii Ihnatenko +1
We consider nonstandard cosmologies in which decaying relics inject energy at MeV temperatures, driving neutrinos out of equilibrium. The subsequent neutrino evolution shapes predi…
SHiP as a (post-)discovery machine: identifying the diphoton signals' origin
Matei Climescu, Malte Fogde Mikkelsen, Maksym Ovchynnikov
The upcoming SHiP experiment may probe interaction strengths of decaying feebly coupled particles several orders of magnitude below existing limits. In the event of a discovery, it…
Rethinking search signatures: Hadronic decays of GeV-scale feebly coupled particles
Viktor Kryshtal, Maksym Ovchynnikov
Experimental searches for GeV-scale feebly interacting particles commonly target the simplest decay signatures with two charged particles, including hadrons. Hadronic modes often d…
Heavy neutral leptons beyond the BBN bound: probing the lepton asymmetry of the Universe
Kensuke Akita, Maksym Ovchynnikov, Vsevolod Syvolap
Hadronically decaying particles with lifetimes are excluded by Big Bang Nucleosynthesis almost independently of their abundance: the mesons from their decay…
Measurement of the muon neutrino charged-current cross section with SND@LHC
LHC Collaboration, D. Abbaneo, S. Ahmad +163
We report a measurement of the muon neutrino charged-current (CC) interaction cross section on tungsten using the electronic detectors of the SND@LHC experiment at the CERN Large H…
Detector performance at SHiP for cascade-produced long-lived particles
Matei Climescu, Yehor Kyselov, Maksym Ovchynnikov
Previous studies have shown that cascade production in the thick target of the SHiP experiment may substantially enhance the number of light long-lived particles (LLPs) decaying in…
What does it take to have at CMB times?
Miguel Escudero, Maksym Ovchynnikov, Neal Weiner
The vast majority of extensions of the Standard Model affecting the number of effective relativistic neutrino species () do so additively, namely, they enhance this qu…
On Exclusive Coherent Production of Bosons in Electron-Proton Collisions
Reuven Balkin, Ta'el Coren, Alexander Jentsch +4
We study the exclusive electroproduction process , with a single-particle final state, in the forward-proton kinematics relevant for the future Electron-Ion Col…
Study of the Run-3 muon flux at the SND@LHC experiment
LHC Collaboration
Long-range muons produced in proton-proton collisions at the ATLAS interaction point constitute the primary background for neutrino interaction searches at the SND@LHC experiment.…
Measurement of the Muon Flux at SND@LHC: Results from the 2023-2025 Proton and Heavy-Ion Periods
LHC Collaboration
The SND@LHC experiment investigates neutrinos in the forward pseudorapidity range. The detector consists of a veto system, a scintillating fiber tracker interleaved…
SND@LHC Upgrade for the High-Luminosity LHC: Physics Reach and Installation Scenarios
LHC Collaboration
The SND@LHC experiment is currently taking data at the Large Hadron Collider (LHC), exploring the unique forward region at pseudorapidities from 7.2 to 8.4. Its physics programme c…
Braking protons at the EIC: from invisible meson decay to new physics searches
Reuven Balkin, Ta'el Coren, Alexander Jentsch +4
We investigate the sensitivity of the Electron-Ion Collider~(EIC) to invisible final states in coherent exclusive electroproduction. The characteristic signal is a forward proton w…
