An effective cosmological collider Open
A bstract 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 redefinitions. We initiate a systematic study of …

Gravitational waves from stochastic scalar fluctuations Open
Here, we present a novel mechanism for gravitational wave generation in the early Universe. Light spectator scalar fields during inflation can acquire a blue-tilted power spectrum due to stochastic effects. We show that this effect can lea…

Dark matter in a mirror solution to the strong problem Open
We study thermal production of dark matter (DM) in a realization of the minimal models of Bonnefoy [], where parity is used to solve the strong CP problem by transforming the entire Standard Model (SM) into a mirror copy. Although the mirr…

The muon Smasher’s guide Open
We lay out a comprehensive physics case for a future high-energy muon collider, exploring a range of collision energies (from 1 to 100 TeV) and luminosities. We highlight the advantages of such a collider over proposed alternatives. We sho…
