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…

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…

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…

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…

Probing axion-like particles at the Electron-Ion Collider

Reuven Balkin, Or Hen, Wenliang Li +4

The Electron-Ion Collider~(EIC), a forthcoming powerful high-luminosity facility, represents an exciting opportunity to explore new physics. In this article, we study the potential…

An EFT hunter's guide to two-to-two scattering: HEFT and SMEFT on-shell amplitudes

Hongkai Liu, Teng Ma, Yael Shadmi +1

We derive the contact terms contributing to the four-point amplitudes of the standard-model particles, keeping terms with up to quartic energy growth. Imposing just the unbroken lo…

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…

Electroweak Phase Transition with an SU(2) Dark Sector

Tathagata Ghosh, Huai-Ke Guo, Tao Han +1

We consider a non-Abelian dark SU(2) model where the dark sector couples to the Standard Model (SM) through a Higgs portal. We investigate two different scenarios of the…

Anomalous dimensions from gauge couplings in SMEFT with right-handed neutrinos

Alakabha Datta, Jacky Kumar, Hongkai Liu +1

Standard Model Neutrino Effective Field Theory (SMNEFT) is an effective theory with Standard Model (SM) gauge-invariant operators constructed only from SM and right-handed neutrino…
