Light Hidden Mesons through the Z Portal
Hsin-Chia Cheng, Lingfeng Li, Ennio Salvioni +1
Confining hidden sectors are an attractive possibility for physics beyond the Standard Model (SM). They are especially motivated by neutral naturalness theories, which reconcile th…
Anatomy of the Physics at HL-LHC
Lingfeng Li, Ying-Ying Li, Tao Liu
The production at colliders contain rich information on the nature of Higgs boson. In this article, we systematically studied its physics at High-Luminosity Large Hadron Col…
Gravitational Production of Superheavy Dark Matter and Associated Cosmological Signatures
Lingfeng Li, Tomohiro Nakama, Chon Man Sou +2
We study the gravitational production of super-Hubble-mass dark matter in the very early universe. We first review the simplest scenario where dark matter is produced mainly during…
Detector-size Upper Bounds on Dark Hadron Lifetime from Cosmology
Lingfeng Li, Yuhsin Tsai
We show that in a confining hidden valley model where the lightest hidden particles are dark hadrons that have mass splittings larger than GeV, if the lightest d…
