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…
Sub-GeV dark matter and multi-decay signatures from dark showers at beam-dump experiments
Elias Bernreuther, Nicoline Hemme, Felix Kahlhoefer +2
In models of strongly-interacting dark sectors, the production of dark quarks at accelerators can give rise to dark showers with multiple dark mesons in the final state. If some of…
Nucleosynthesis and CMB bounds on photophilic ALPs: a fresh look
Miguel Escudero, Clara Garcia-Perez, Maksym Ovchynnikov
We provide a fresh look at the cosmological constraints on axion-like particles (ALPs) that couple predominantly to photons, focusing on lifetimes $Ï_{a} \lesssim 10^{4}\, {\rm s}…
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…
