Dark Matter Freeze Out during an Early Cosmological Period of QCD Confinement
Dillon Berger, Seyda Ipek, Tim M. P. Tait +1
Standard lore states that there is tension between the need to accommodate the relic density of a weakly interacting massive particle and direct searches for dark matter. However,…

Dark Matter Through the Quark Vector Current Portal
Dillon Berger, Arvind Rajaraman, Jason Kumar
We consider models of light dark matter coupled to quarks through a vector current interaction. For low energies, these models must be treated through the effective couplings to me…

Invariant Tensors in Gauge Theories
Dillon Berger, Jessica N. Howard, Arvind Rajaraman
Invariant tensors play an important role in gauge theories, for example, in dualities of N=1 gauge theories. However, for theories with fields in representations larger than the fu…
