Heavy QCD Axions at High-Energy Muon Colliders
Ravneet Bedi, Tony Gherghetta, Soubhik Kumar +2
We study the physics potential of heavy QCD axions at high-energy muon colliders. Unlike typical axion-like particles, heavy QCD axions solve the strong CP problem with phenomenolo…

An Effective Cosmological Collider
Nathaniel Craig, Soubhik Kumar, Amara McCune
Effective field theories (EFTs) of heavy particles coupled to the inflaton are rife with operator redundancies, frequently obscured by sensitivity to both boundary terms and field…
