Searching for elusive dark Higgs boson in spin-1/2 inelastic dark matter models at Belle II
P. Ko, Youngjoon Kwon, Chih-Ting Lu +1
Spin-1/2 inelastic dark matter (DM) models are popular among sub-GeV to GeV thermal DM scenarios due to the dominant role of co-annihilation in determining the DM relic abundance.…

Exploring Exotic Decays of the Higgs Boson to Multi-Photons at the LHC via Multimodal Learning Approaches
A. Hammad, P. Ko, Chih-Ting Lu +1
The Standard Model (SM) Higgs boson, the most recently discovered elementary particle, may still serve as a mediator between the SM sector and a new physics sector related to dark…

Detecting highly collimated photon-jets from Higgs boson exotic decays with deep learning
Xiaocong Ai, William Y. Feng, Shih-Chieh Hsu +2
Recently, there has been a growing focus on the search for anomalous objects beyond standard model (BSM) signatures at the Large Hadron Collider (LHC). This study investigates nove…
