Constraints on Loryons in a Two Higgs Doublet Model
Can Kilic, Sanjay Mathai, Taewook Youn
We consider Loryons, particles beyond the Standard Model that receive a significant fraction of their masses from electroweak symmetry breaking, in the context of a two Higgs doubl…
Resonant Enhancement for the transfer of baryon number from a CP-violating hidden sector
Can Kilic, Sanjay Mathai
We consider a scenario where the baryon asymmetry in the SM arises from a portal coupling to a CP-violating hidden sector, without any explicit violation of baryon or lepton number…
Long-Lived-Particle Signals of a Composite Hidden Sector through the Neutrino Portal
Aqeel Ahmed, Zackaria Chacko, Niral Desai +4
We explore the signals of a scenario in which the composite states of a strongly coupled hidden sector couple to the Standard Model through the neutrino portal, giving rise to the…
Dark Matter-Dark Radiation Interactions and the Hubble Tension
Manuel A. Buen-Abad, Zackaria Chacko, Ina Flood +3
Models in which a subcomponent of dark matter interacts with dark radiation have been proposed as a solution to the Hubble tension. In this framework, the interacting subcomponent…
Searching for Hidden Sector Particles at Neutrino Telescopes
Sagar Airen, Zackaria Chacko, Can Kilic +1
We explore the possibility of directly detecting light, long-lived hidden sector particles at the IceCube neutrino telescope. Such particles frequently arise in non-minimal hidden…
General form of effective operators from hidden sectors
Aqeel Ahmed, Zackaria Chacko, Ina Flood +2
We perform a model-independent analysis of the dimension-six terms that are generated in the low energy effective theory when a hidden sector that communicates with the Standard Mo…
