A Light QCD Axion with Hilltop Misalignment
Raymond T. Co, Tony Gherghetta, Zhen Liu +1
We study the cosmological evolution of a light QCD axion and identify the parameter space to obtain the correct relic dark matter abundance. The axion potential is flattened at the…

Long-Lived Particles at the Energy Frontier: The MATHUSLA Physics Case
David Curtin, Marco Drewes, Matthew McCullough +85
We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a comprehensive survey of Standard Model (SM) extensions. LLPs are a common prediction of…

Freeze-In Dark Matter with Displaced Signatures at Colliders
Raymond T. Co, Francesco D'Eramo, Lawrence J. Hall +1
Dark matter, , may be generated by new physics at the TeV scale during an early matter-dominated (MD) era that ends at temperature . Compared to the conventio…
