Electron-Ion Collider as a Discovery Tool for Invisible Dark Bosons
Hooman Davoudiasl, Hongkai Liu
We illustrate how the future Electron-Ion Collider (EIC) can be used to discover dark bosons with masses in the (10~MeV -- 10~GeV) regime, having a wide range of properties.…
Probing new hadronic forces with heavy exotic atoms
Hongkai Liu, Ben Ohayon, Omer Shtaif +1
We explore the potential of precision spectroscopy of heavy exotic atoms where electrons are substituted by negative hadrons to detect new force carriers with hadronic couplings. T…
Right-handed Dirac and Majorana neutrinos at Belle II
Tao Han, Jiajun Liao, Hongkai Liu +1
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…
Dimension-8 SMEFT contact-terms for vector-pair production via on-shell Higgsing
Jared M Goldberg, Hongkai Liu, Yael Shadmi
We derive the dimension-8 standard-model effective theory (SMEFT) contact terms relevant for vector-pair production at the LHC and lepton colliders. We first list the relevant dime…
Constraining neutrinophilic mediators at FASER, FLArE and FASER2
Weidong Bai, Jiajun Liao, Hongkai Liu
High energy collider neutrinos have been observed for the first time by the FASER experiment. The detected spectrum of collider neutrinos scattering off nucleons can be used to…
New Physics at the Muon (Synchrotron) Ion Collider: MuSIC for several scales
Hooman Davoudiasl, Hongkai Liu, Roman Marcarelli +2
A Muon (Synchrotron) Ion Collider (MuSIC) can be the successor to the Electron-Ion Collider at Brookhaven National Laboratory, as well as the ideal demonstrator facility for a futu…
