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…

-Boson Exotic Decay into Three Charged Leptons at the LHC

Yifan Fei, Peiran Li, Zhen Liu +2

We investigate the boson's exotic decay channel, , at the LHC. Although the four-body final states suppress the decay branching ratio, the large p…

A Light QCD Axion with Hilltop Misalignment

Raymond T. Co, Tony Gherghetta, Zhen Liu +1

We study the cosmological evolution of a light QCD axion and identify the parameter space to obtain the correct relic dark matter abundance. The axion potential is flattened at the…

Higgs Width and Couplings at High Energy Muon Colliders with Forward Muon Detection

Peiran Li, Zhen Liu, Kun-Feng Lyu

We propose a novel method using the -fusion channel and forward muon detection at high-energy muon colliders to address the challenge of the Higgs coupling-width degeneracy. Ou…
