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…

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 Hi…

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…
