Frank F. Deppisch, Suchita Kulkarni, Wei Liu

TL;DR
This paper explores the potential of the MAPP detector at MoEDAL to detect right-handed neutrinos via B-L gauge interactions, achieving sensitivities to very small active-sterile mixing angles.
Contribution
It introduces a novel search strategy for right-handed neutrinos at MAPP through B-L and Z boson portals, with sensitivity estimates near current experimental limits.
Findings
MAPP can detect active-sterile mixing as low as 10^{-12}
Sensitivity is comparable via B-L and SM Z boson portals
Effective mixing can be probed down to 0.002
Abstract
The possibility of searching for right-handed neutrinos at the MoEDAL's Apparatus for Penetrating Particles (MAPP) detector is investigated in this work. In particular, pair-production of right-handed (RH) neutrinos from either a gauge boson , as well as Standard Model (SM) boson are considered. Under a no-background assumption, we show that the MAPP detector can be sensitive to active-sterile neutrino mixing strengths as low as for multiple choices of values, when taking the gauge coupling near its current limit. The SM boson portal can reach a similar sensitivity, when the effective mixing between the and SM gauge boson is .
