Complete Light Long-Lived Particles searches in Type-I 2HDM
Xueying Qi, Huayang Song, Wei Su
Recently, the study of long-lived particles (LLPs) has attracted increasing attention. In this work, we analyze the full parameter space of the Type-I Two-Higgs-Doublet Model (2HDM…
Charged Higgs Search in 2HDM
Juxiang Li, Huayang Song, Shufang Su +1
In this paper, we present a comprehensive study of the collider search limits on the charged Higgses in the four types of Two Higgs Double Models (2HDM). In addition to constraints…
Complete EFT Operator Bases for Dark Matter and Weakly-Interacting Light Particle
Huayang Song, Hao Sun, Jiang-Hao Yu
The standard model can be extended to include weakly-interacting light particle (WILP): real or complex singlet scalar, Majorana or Dirac neutral fermion, neutral or hidden-charged…
Effective Field Theories of Axion, ALP and Dark Photon
Huayang Song, Hao Sun, Jiang-Hao Yu
With the help of Young tensor technique, we enumerate the complete and independent set of effective operators up to -8 for the extension of the standard model with a Goldsonte…
Light Scalars at FASER
Shuailong Li, Huayang Song, Shufang Su +1
FASER, the ForwArd Search ExpeRiment, is a currently operating experiment at the Large Hadron Collider (LHC) that can detect light long-lived particles produced in the forward regi…
Custodial Symmetry Violation in Scalar Extensions of the Standard Model
Huayang Song, Xia Wan, Jiang-Hao Yu
The new measurement of the W boson mass from the CDF collaboration shows a significant tension with the Standard Model prediction, which evidences violation of custodial symmetry i…
Exotic Higgs Decays in the Type-II 2HDMs at Current and Future pp Colliders
Felix Kling, Honglei Li, Shuailong Li +4
