Melting LHC detectors: a novel search for stopped long-lived particles

Julia L. Gonski, Peter W. Graham, Surjeet Rajendran +2

Particles at the TeV scale with lifetimes of a year or longer could have been abundantly produced at the LHC yet escaped detection because of backgrounds, and could still be trappe…

Cosmological Limits on Strong Dark Forces

Peter W. Graham, Harikrishnan Ramani, Olivier Simon +1

We showcase cosmology's ability to constrain long-range forces between dark matter particles. Specifically, we consider a fermionic dark matter interacting via a Yukawa-coupled lig…

Electric Accumulation of Millicharged Particles

Asher Berlin, Zachary Bogorad, Peter W. Graham +1

A terrestrial population of millicharged particles that interact significantly with normal matter can arise if they make up a dark matter subcomponent or if they are light enough t…

Cavendish Tests of Millicharged Particles

Asher Berlin, Zachary Bogorad, Peter W. Graham +1

A terrestrial population of room-temperature millicharged particles can arise if they make up a dark matter subcomponent or if they are light enough to be produced in cosmic ray ai…

Robust bounds on MACHOs from the faintest galaxies

Peter W. Graham, Harikrishnan Ramani, Maximilian Ruhdorfer

We use the dynamical heating of stars in ultrafaint dwarf (UFD) galaxies to set limits on Massive Compact Halo Objects (MACHOs). In our analysis we study the robustness of the boun…

Revisiting Isocurvature Bounds on the Minimal QCD Axion

Peter W. Graham, Davide Racco

The QCD axion has important connections to early universe cosmology. For example, it is often said that isocurvature limits rule out a combination of high axion decay constant, $f_…
