Hidden Naturalness at Colliders and in Cosmology

Abstract: One of the enduring mysteries in particle physics is the lightness of the Higgs mass which is known as the electroweak hierarchy problem. Traditionally, colliders have been the leading tool to search for theories that solve this problem. In recent years, however, data from the Large Hadron Collider has tightened the parameter space of these theories. This has motivated the exploration of theories of hidden naturalness, or neutral naturalness, where the most common collider signatures are absent. Such theories may still have some, less conventional, collider signatures, but more often face the strongest constraints from cosmological observations. I will present two such theories, twin Higgs and N-naturalness, and discuss their complementary signals at colliders and in cosmology.
Bio: Matthew Low is currently a postdoctoral research associate at the University of Pittsburgh. His research focuses on beyond the Standard Model physics which includes model building, collider physics, and new physics in cosmology. Recently, he has also been working on the study of quantum information at colliders. Previously, he was a postdoctoral research associate at Fermilab from 2018 - 2021 and a member at the Institute for Advanced Study from 2015 - 2018. He completed his PhD at the University of Chicago in 2015.
