Exotic Higgs Decays at a Muon Collider
JiJi Fan, Lingfeng Li, Tao Liu +2
We study the sensitivity of a future muon collider to exotic Higgs decays in a minimal scenario of Standard Model (SM) augmented with a light singlet scalar . We consider the de…

Dark Matter on a Slide
Hsin-Chia Cheng, Xu-Hui Jiang, Lingfeng Li +1
We present a scenario for GeV-scale thermal dark matter that can only be tested with accelerator experiments. Dark matter is composed of dark pions arising from a confining strong…

Limits on an Exotic Higgs Decay From a Recast ATLAS Four-Lepton Analysis
Junyi Cheng, Rabia Husain, Lingfeng Li +1
The ATLAS collaboration, using 139 fb of 13 TeV collisions from the Large Hadron Collider, has placed limits on the decay of a boson to three dark photons. We reproduce…
