Neutrino-Antineutrino Conversion from Ultralight Vector Dark Matter
Asher Berlin, Rodolfo Capdevilla, Ting Cheng +2
We show that Majorana neutrinos convert into antineutrinos in a background of ultralight vector dark matter coupled to lepton number, such as the gauge boson of …
Building an AI-native Research Ecosystem for Experimental Particle Physics: A Community Vision
Thea Klaeboe Aarrestad, Alaa Abdelhamid, Haider Abidi +457
Experimental particle physics seeks to understand the universe by probing its fundamental particles and forces and exploring how they govern the large-scale processes that shape co…
MuCol Milestone Report No. 7: Consolidated Parameters
Rebecca Taylor, Antoine Chancé, Dario Augusto Giove +459
This document is comprised of a collection of consolidated parameters for the key parts of the muon collider. These consolidated parameters follow on from the October 2024 Prelimin…
Electroweak Symmetry Restoration and Radiation Amplitude Zeros
Rodolfo Capdevilla, Tao Han
In high-energy collisions far above the electroweak scale, the effects of electroweak symmetry breaking are expected to become parametrically small . This defines the…
High-Frequency Gravitational Waves on BREAD
Rodolfo Capdevilla, Roni Harnik, Taegyun Kim +1
The use of light axion dark matter experiments as high-frequency gravitational wave (HFGW) detectors has garnered increasing attention in recent years. We explore the capabilities…
Gravitational Photon Polarization Twist to Probe the Early Universe and the Galactic Center
Rodolfo Capdevilla
It is known that gravitational wave backgrounds (GWBs) change the polarization state of photons. This letter explores the possibility of using this effect to detect GWBs. The propo…
