Imperfect axions with no domain wall problem
Marco Gorghetto, Edward Hardy, Gilad Perez +1
Post-inflationary axion theories with domain wall number suffer from a domain wall problem. We show analytically, and confirm via simulations, that there is a region of pheno…
A Generic Formation Mechanism of Ultralight Dark Matter Solar Halos
Dmitry Budker, Joshua Eby, Marco Gorghetto +2
As-yet undiscovered light bosons may constitute all or part of the dark matter (DM) of our Universe, and are expected to have (weak) self-interactions. We show that the quartic sel…
From axion quality and naturalness problems to a high-quality QCD relaxion
Abhishek Banerjee, Joshua Eby, Gilad Perez
We highlight general issues associated with quality and naturalness problems in theories of light QCD-axions, axion-like particles, and relaxions. We show the presence of Planck-su…
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…
