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…
Stepped Partially Acoustic Dark Matter: Likelihood Analysis and Cosmological Tensions
Manuel A. Buen-Abad, Zackaria Chacko, Can Kilic +2
We generalize the recently proposed Stepped Partially Acoustic Dark Matter (SPartAcous) model by including additional massless degrees of freedom in the dark radiation sector. We f…
Composite Dark Matter and Neutrino Masses from a Light Hidden Sector
Aqeel Ahmed, Zackaria Chacko, Niral Desai +3
We study a class of models in which the particle that constitutes dark matter arises as a composite state of a strongly coupled hidden sector. The hidden sector interacts with the…
Muon Collider Forum Report
K. M. Black, S. Jindariani, D. Li +182
A multi-TeV muon collider offers a spectacular opportunity in the direct exploration of the energy frontier. Offering a combination of unprecedented energy collisions in a comparat…
Stepped Partially Acoustic Dark Matter, Large Scale Structure, and the Hubble Tension
Manuel A. Buen-Abad, Zackaria Chacko, Can Kilic +2
We propose a new interacting dark sector model, Stepped Partially Acoustic Dark Matter (SPartAcous), that can simultaneously address the two most important tensions in current cosm…
