An Axial : UV Completion and Experimental Searches
Rundong Fang, Jinhui Guo, Ming Li +3
We propose an anomaly-free and renormalizable axial model and study its experimental signatures for masses from the MeV scale to the TeV scale. The opposite…
Down-Type Jet Identification in Fully Hadronic Events
Jinhui Guo, Chenhao Peng
Fully hadronic events carry the largest branching fraction and provide the down-type quark as a near-maximal spin analyzer (), yet they are rarely used for sp…
Supermassive Primordial Black Holes from a Catalyzed Dark Phase Transition for Little Red Dots
Jinhui Guo, Jia Liu, Masanori Tanaka +2
JWST has revealed an abundant population of compact, low-metallicity "Little Red Dots" (LRDs) at high redshift, challenging conventional scenarios in which supermassive black holes…
Ultralight Scalar Dark Matter with Off-Diagonal Flavor Couplings
Jinhui Guo, Jia Liu, Chenhao Peng +2
Ultralight dark matter can behave as a coherent background field and induce time-dependent modifications of Standard Model parameters. We study a scenario in which a real ultraligh…
Probing Scalar-Mediated Sterile Neutrinos with Gravitational Wave and Colliders Signals
Qi Bi, Jinhui Guo, Jian Liao +2
We propose a UV-complete extension of the Standard Model in which a gauge-singlet scalar acquires a vacuum expectation value, generates a Majorana mass for a sterile neutrino $…
Probing Purely Inelastic Scalar Dark Matter Across Colliders and Gravitational Wave Observatories
Jinhui Guo, Jia Liu, Chenhao Peng +1
We propose and study a purely inelastic scalar dark matter model, where two real scalars-dark matter and its excited partner interact with the Standard Model via a Higg…
Long-lived Sterile Neutrino Searches at Future Muon Colliders
Qi Bi, Jinhui Guo, Jia Liu +2
We explore the potential of studying sterile neutrinos at a future high-energy muon collider, where these particles can generate small active neutrino masses via the seesaw mechani…
Long-lived Searches of Vector-like Lepton and Its Accompanying Scalar at Colliders
Qing-Hong Cao, Jinhui Guo, Jia Liu +2
Recently, the vector-like leptons (VLLs) as a simple extension to the standard model (SM) have attracted widespread attention both in theory and experiments. The present collider s…
New mechanism for primordial black hole formation from the QCD axion
Shuailiang Ge, Jinhui Guo, Jia Liu
We present a new mechanism for the primordial black hole (PBH) production within the QCD axion framework. We take the case where the Peccei-Quinn symmetry breaks during inflation,…
Unveiling Time-Varying Signals of Ultralight Bosonic Dark Matter at Collider and Beam Dump Experiments
Jinhui Guo, Yuxuan He, Jia Liu +2
The ultralight boson represents a promising dark matter candidate exhibiting unique wave-like behaviors. These properties could transfer to the dark mediator, such as the kinetic m…
Heavy long-lived coannihilation partner from inelastic Dark Matter model and its signatures at the LHC
Jinhui Guo, Yuxuan He, Jia Liu +1
The coannihilation mechanism is a well-motivated alternative to the simple thermal freeze-out mechanism, where the dark matter relic density can be obtained through the coannihilat…
