Universal Seesaw Leptogenesis
K. S. Babu, Maximilian Berbig, Srubabati Goswami +1
We study the implications for leptogenesis in a class of left-right symmetric model, where all fermion masses are induced through the Universal Seesaw mechanism. Unlike conventiona…
Generalised Casas-Ibarra Parametrisation for Majorana Neutrino Masses
Juan Herrero-García, Simone Marciano, Juan Racker +1
We present a simple and broadly applicable extension of the Casas-Ibarra parametrisation that captures the structure of all Majorana neutrino mass models. Building directly on the…
Probing Light Primordial Black Holes through Non-cold Dark Matter
Yu-Ming Chen
We study the matter power spectrum constraint on primordial black holes (PBH) by the dark matter (DM) emitted through Hawking radiation. We particularly focus on the scenario where…
A Practical Guide to Unbinned Unfolding
Florencia Canelli, Kyle Cormier, Andrew Cudd +12
Unfolding, in the context of high-energy particle physics, refers to the process of removing detector distortions in experimental data. The resulting unfolded measurements are stra…
Leptogenesis and Neutrino Masses Via Pseudo-Dirac Gauginos
Cem Murat Ayber, Tammi Chowdhury, Seyda Ipek
In a -symmetric supersymmetric model, pseudo-Dirac bino and wino can act like right-handed neutrinos, generating the light neutrino masses through a hybrid Type I + III…
Dark Matter Candidates and Searches
Nassim Bozorgnia, Joseph Bramante, James M. Cline +7
Astrophysical observations suggest that most of the matter in the cosmos consists of a new form that has not been observed on Earth. The nature and origin of this mysterious dark m…
