The Hydrogen Mixing Portal, Its Origins, and Its Cosmological Effects
Lucas Johns, Seth Koren
Hydrogen oscillation into a dark-sector state has recently been proposed as a novel mechanism through which hydrogen can be cooled during the dark ages -- without direct coupl…
Hydrogen Mixing as a Novel Mechanism for Colder Baryons in 21 cm Cosmology
Lucas Johns, Seth Koren
The anomalous 21 cm absorption feature reported by EDGES has galvanized the study of scenarios in which dark matter (DM) siphons off thermal energy from the Standard Model (SM) gas…
The Hierarchy Problem: From the Fundamentals to the Frontiers
Seth Koren
We begin this thesis with an extensive pedagogical introduction aimed at clarifying the foundations of the hierarchy problem. After introducing effective field theory, we discuss r…
Supersoft Stops
Timothy Cohen, Nathaniel Craig, Seth Koren +2
In a supersymmetric (SUSY) theory, the IR-contributions to the Higgs mass are calculable below the mediation scale in terms of the IR field content and parameters.…
