Cosmic Strings in Hidden Sectors: 2. Cosmological and Astrophysical Signatures
Andrew J. Long, Tanmay Vachaspati
Cosmic strings can arise in hidden sector models with a spontaneously broken Abelian symmetry group. We have studied the couplings of the Standard Model fields to these so-called d…
Cosmic Strings in Hidden Sectors: 1. Radiation of Standard Model Particles
Andrew J. Long, Jeffrey M. Hyde, Tanmay Vachaspati
In hidden sector models with an extra U(1) gauge group, new fields can interact with the Standard Model only through gauge kinetic mixing and the Higgs portal. After the U(1) is sp…
Detecting non-relativistic cosmic neutrinos by capture on tritium: phenomenology and physics potential
Andrew J. Long, Cecilia Lunardini, Eray Sabancilar
We study the physics potential of the detection of the Cosmic Neutrino Background via neutrino capture on tritium, taking the proposed PTOLEMY experiment as a case study. With the…
