Prospects for Detecting Boosted Dark Matter in DUNE through Hadronic Interactions

Joshua Berger, Yanou Cui, Mathew Graham +5

Boosted dark matter (BDM) is a well-motivated class of dark matter (DM) candidates in which a small component of DM is relativistic at the present time. We lay the foundation for B…

Subleading Power Resummation of Rapidity Logarithms: The Energy-Energy Correlator in SYM

Ian Moult, Gherardo Vita, Kai Yan

We derive and solve renormalization group equations that allow for the resummation of subleading power rapidity logarithms. Our equations involve operator mixing into a new class o…

Towards A UV-Model of Kinetic Mixing and Portal Matter

Thomas D. Rueter, Thomas G. Rizzo

The nature of dark matter (DM) and how it might interact with the particles of the Standard Model (SM) is an ever-growing mystery. It is possible that the existence of new `dark se…

Direct Deflection of Particle Dark Matter

Asher Berlin, Raffaele Tito D'Agnolo, Sebastian A. R. Ellis +2

We propose a new strategy to directly detect light particle dark matter that has long-ranged interactions with ordinary matter. The approach involves distorting the local flow of d…
