Constraints on Decaying Dark Matter with from Fermi-LAT

Can Kilic, Zhi-Xiang Yang, Taewook Youn

We investigate the gamma ray signatures of fermionic dark matter that carries one unit of baryon number and decays into three quarks. We compute the expected prompt and secondary g…

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…

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…

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…

Atomic Dark Matter, Interacting Dark Radiation, and the Hubble Tension

Manuel A. Buen-Abad, Zackaria Chacko, Ina Flood +3

We present a new class of interacting dark sector models that can address the Hubble tension. Interacting dark radiation (DR) has previously been put forward as a solution to the p…
