Light Weakly Coupled Axial Forces: Models, Constraints, and Projections
Yonatan Kahn, Gordan Krnjaic, Siddharth Mishra-Sharma +1
We investigate the landscape of constraints on MeV-GeV scale, hidden U(1) forces with nonzero axial-vector couplings to Standard Model fermions. While the purely vector-coupled dar…
Thermal Dark Matter From A Highly Decoupled Sector
Asher Berlin, Dan Hooper, Gordan Krnjaic
It has recently been shown that if the dark matter is in thermal equilibrium with a sector that is highly decoupled from the Standard Model, it can freeze-out with an acceptable re…
Dark Sectors 2016 Workshop: Community Report
Jim Alexander, Marco Battaglieri, Bertrand Echenard +201
This report, based on the Dark Sectors workshop at SLAC in April 2016, summarizes the scientific importance of searches for dark sector dark matter and forces at masses beneath the…
Dark matter search in a Beam-Dump eXperiment (BDX) at Jefferson Lab
M. Battaglieri, A. Bersani, B. Caiffi +101
MeV-GeV dark matter (DM) is theoretically well motivated but remarkably unexplored. This proposal presents the MeV-GeV DM discovery potential for a 1 m segmented CsI(Tl)…
Can the Baryon Asymmetry Arise From Initial Conditions?
Gordan Krnjaic
In this letter, we quantify the challenge of explaining the baryon asymmetry using initial conditions in a universe that undergoes inflation. Contrary to lore, we find that such an…
PeV-Scale Dark Matter as a Thermal Relic of a Decoupled Sector
Asher Berlin, Dan Hooper, Gordan Krnjaic
In this letter, we consider a class of scenarios in which the dark matter is part of a heavy hidden sector that is thermally decoupled from the Standard Model in the early universe…
