Search for Light Dark Sectors Using Electron-Photon Collisions
L. Angel, G. Casse, G. Gambini +6
The dark photon is a new gauge boson that naturally arises in many beyond the Standard Model theoretical models, featuring interactions that resemble quantum electrodynamics. Due t…
Probing the Dark Matter EFT with QUEST-DMC: Projected Sensitivities and Attenuation Ceilings
DMC Collaboration, N. Darvishi, S. Autti +27
This proceedings contribution summarises projected constraints from the QUEST-DMC concept, a surface-based direct-detection experiment using superfluid He operated below the mi…
Minimal Dark Matter: Generalized Framework and Direct-Detection Sensitivity
Spencer Griffith, Juri Smirnov, Laura Lopez-Honorez +1
Minimal electroweak dark matter models are compelling due to their simplicity, though calculations of their freezeout abundance are complicated by nonperturbative effects due to So…
Deep learning optimal molecular scintillators for dark matter direct detection
Cameron Cook, Carlos Blanco, Juri Smirnov
Direct searches for sub-GeV dark matter are limited by the intrinsic quantum properties of the target material. In this proof-of-concept study, we argue that this problem is partic…
Dark Dwarfs: Dark Matter-Powered Sub-Stellar Objects Awaiting Discovery at the Galactic Center
Djuna Croon, Jeremy Sakstein, Juri Smirnov +1
We investigate the effects of dark matter annihilation on objects with masses close to the sub-stellar limit, finding that the minimum mass for stable hydrogen burning is larger th…
Dynamical Dark Energy Emerges from Massive Gravity
Juri Smirnov
In this work, we demonstrate that a dynamical dark energy component predicted by massive gravity gives rise to a distinctive evolution of the equation of state. This scenario is fa…
