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 …
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…
Radiative corrections relating leptoquark-fermion couplings probed at low and high energy
Innes Bigaran, Rodolfo Capdevilla, Ulrich Nierste
Scalar leptoquarks (LQ) with masses between 2 TeV and 50 TeV are prime candidates to explain deviations between measurements and Standard-Model predictions in decay observables of…
Gravitational Wave Detection With Plasma Haloscopes
Rodolfo Capdevilla, Graciela B. Gelmini, Jonah Hyman +2
Searches for high frequency gravitational waves using cavities based on the Gertsenshtein effect were recently proposed, building off existing axion dark matter experiments. In par…
