Probing eV-scale sterile neutrinos with neutrinoless double-beta decay and beta decay
Ruisha Yang, Jiajun Liao
An eV-scale sterile Majorana neutrino can suppress neutrinoless double-beta decay through destructive interference with the active-neutrino contribution, weakening the resulting co…
Testing for coherence and nonstandard neutrino interactions in COHERENT data

Probing general models with non-universal lepton charges at FASER/FASER2, COHERENT and long-baseline oscillation experiments
Tobias Felkl, Tong Li, Jiajun Liao +1
The general anomaly-free models allow non-universal lepton charges. We explore the sensitivities of FASER/FASER2, COHERENT and DUNE/T2HK precision experiments to the new ga…
How to measure the reactor neutrino flux below the inverse beta decay threshold with CENS
Jiajun Liao, Hongkai Liu, Danny Marfatia
Most antineutrinos produced in a nuclear reactor have energies below the inverse beta decay threshold, and have not yet been detected. We show that a coherent elastic neutrino-nucl…

We assess the ability of the Belle II experiment to probe the Dirac or Majorana nature of a massive right-handed neutrino (RHN) in the MeV to GeV mass range. We consider the pr…
Constraining super-light sterile neutrinos at Borexino and KamLAND
Zikang Chen, Jiajun Liao, Jiajie Ling +1
The presence of a super-light sterile neutrino can lead to a dip in the survival probability of solar neutrinos, and explain the suppression of the upturn in the low energy solar n…
