Charged Higgs Search at Future Neutrino Telescope and Higgs Factory
YiCheng Dai, Wei Liao, Yi-Song Lu +1
We investigate the discovery potential of the charged Higgs boson at future lepton colliders and neutrino telescopes within two simplified benchmark scenarios with universal Yukawa…
Lyman- Forest Constraint on Dark Matter from Dark Sector Decay
Si-Yuan Zhao, Yi-Cheng Dai, Wei Liao +1
By exploiting small-scale structure formation probed by Lyman- forest observations, we study constraints on a model of dark matter from dark sector decay. We compute the phase…
Neutrino masses, matter-antimatter asymmetry, dark matter, and supermassive black hole formation explained with Majorons
Yifan Lu, Zachary S. C. Picker, Alexander Kusenko +1
The spontaneous breaking of a global lepton number symmetry can result in a (pseudo) Nambu-Goldstone boson known as the Majoron. We study a singlet Majoron model that couples to tw…
When Tiny Halos Stir Spacetime: Gravitational Waves from Fifth-Force Mergers
Xinpeng Wang, Yifan Lu, Zachary S. C. Picker +2
Dark matter fermions interacting via attractive fifth forces mediated by a light mediator can form dark matter halos in the very early universe. We show that bound systems composed…
Incentivizing supplemental math assignments and using AI-generated hints is associated with improved exam performance
Yifan Lu, K. Supriya, Shanna Shaked +2
Inequities in student access to trigonometry and calculus are often associated with racial and socioeconomic privilege, and often influence introductory physics course performance.…
Black Holes from Fermi Ball Collapse
Yifan Lu, Zachary S. C. Picker, Stefano Profumo +1
Fermi balls are non-topological solitons that can naturally form in an early universe containing a dark sector with heavy fermions and an attractive interaction mediated by a light…
