Hydrodynamic effective field theory and the analyticity of hydrostatic correlators
Akash Jain, Pavel Kovtun, Adam Ritz +1
We study one-loop corrections to retarded and symmetric hydrostatic correlation functions within the Schwinger-Keldysh effective field theory framework for relativistic hydrodynami…
New limits on dark photons from solar emission and keV scale dark matter
Haipeng An, Maxim Pospelov, Josef Pradler +1
We provide updates to the limits on solar emission of dark photons, or more generally any light vector particle coupled to the electron vector current. The recent 2019 and 2020 ele…
LSND Constraints on the Higgs Portal
Saeid Foroughi-Abari, Adam Ritz
High-luminosity fixed target experiments provide impressive sensitivity to new light weakly coupled degrees of freedom. We revisit the minimal case of a scalar singlet coupled…
On sub-GeV Dark Matter Production at Fixed-Target Experiments
Asher Berlin, Patrick deNiverville, Adam Ritz +2
We analyze the sensitivity of fixed-target experiments to sub-GeV thermal relic dark matter models, accounting for variations in both mediator and dark matter mass, and including d…
