A Busy Higgs Signal
Peiran Li, Zhen Liu, Lian-Tao Wang
Higgs final states are prime targets in the search for physics beyond the Standard Model. In the conventional picture, symmetry together with the Goldstone Equivalence Theo…
Z Boson Radiative Decay at the LHC
Yifan Fei, Peiran Li, Zhen Liu +1
We study the radiative decay of the boson, , at the LHC, providing both Standard Model (SM) precision analysis and new physics projections. With detailed analysi…
LHC Shines on Positivity
Zhen Liu, Kun-Feng Lyu, Tong Arthur Wu
We show that hadron colliders have an excellent reach for positivity tests on a class of diphoton operators. Due to the helicity selection rules, the relevant dimension-6 operators…
Heavy QCD Axions at High-Energy Muon Colliders
Ravneet Bedi, Tony Gherghetta, Soubhik Kumar +2
We study the physics potential of heavy QCD axions at high-energy muon colliders. Unlike typical axion-like particles, heavy QCD axions solve the strong CP problem with phenomenolo…
