Unveiling the Invisible: ALPs and Sterile Neutrinos at the LHC and HL-LHC

Kingman Cheung, C. J. Ouseph, Sin Kyu Kang

We investigate the potential of using the signature of mono-Higgs plus large missing energies to constrain on two new physics models, namely the model of an axion-like particle (AL…

Can a pseudoscalar with a mass of 365 GeV in two-Higgs-doublet models explain the CMS excess?

Chih-Ting Lu, Kingman Cheung, Dongjoo Kim +2

We investigate the recently reported excess by the CMS Collaboration within the framework of conventional Two-Higgs-Doublet Models (2HDMs). Considering all four types (I…

Exploring interference effects between two ALP effective operators at the LHC

Kingman Cheung, Chih-Ting Lu, C. J. Ouseph +1

We observe that most studies of axion-like particle (ALP) production channels at the Large Hadron Collider (LHC) focus on a single type of ALP operator for each process in the effe…

Effects of Superradiance in Active Galactic Nuclei

Priyanka Sarmah, Himanshu Verma, Kingman Cheung +1

A supermassive black hole (SMBH) at the core of an active galactic nucleus (AGN) provides room for the elusive ultra-light scalar particles (ULSP) to be produced through a phenomen…

Probing the Gauge-boson Couplings of Axion-like Particle at the LHC and High-Luminosity LHC

Kingman Cheung, Wanyon Hsiao, C. J. Ouseph +1

In this work, we calculate the sensitivities on the gauge-boson couplings , , and of an axion-like particle (ALP) that one can achieve at the LHC with $…

Interpretation of excess in using a light axion-like particle

Kingman Cheung, C. J. Ouseph

We interpret the recent excess in a rare decay of the Higgs boson, , using a light axion-like particle (ALP) in the massrange GeV.The dominant decay of such a…
