Strongest constraints on dark acoustic oscillations from the Lyman-alpha forest
Zhihan Yuan, Caleb Gemmell, Keir K. Rogers +4
We set the first constraints on a small-scale dark acoustic oscillation (DAO) in the linear matter power spectrum arising from dark sector interactions, with a full forward model o…
CMB Spectral Distortions from Resonant Conversions in Atomic Dark Sectors
Duncan K. Adams, Jared Barron, Bryce Cyr +1
Dark sectors consisting of atomic constituents (electrons, protons, and photons) offer a well-motivated extension to the Standard Model while providing multiple avenues for phenome…
Pushing the Limits of Atomic Dark Matter: First-Principles Recombination Rates and Cosmological Constraints
Jared Barron, Rouven Essig, Megan H. McDuffie +2
Minimal atomic dark matter with its distinctive cooling mechanisms offers an instructive framework for understanding the potential impact of dark matter on small-scale structure fo…
Constraining Dark Acoustic Oscillations with the High-Redshift UV Luminosity Function
Jared Barron, David Curtin, Hongwan Liu +2
Dark acoustic oscillations (DAOs) in the matter power spectrum can arise in many different dark sector models, and can imprint on a variety of cosmological observables. In this wor…
MATHUSLA: An External Long-Lived Particle Detector to Maximize the Discovery Potential of the HL-LHC
Branden Aitken, Cristiano Alpigiani, Juan Carlos Arteaga-Velázquez +70
We present the current status of the MATHUSLA (MAssive Timing Hodoscope for Ultra-Stable neutraL pArticles) long-lived particle (LLP) detector at the HL-LHC, covering the design, f…
