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…
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…
