Lyα forest bounds on sterile neutrino production via neutrino self-interactions
Priyank Parashari, Vera Gluscevic, Yue Zhang +3
Sterile neutrinos in the keV mass range have long been considered a well-motivated dark matter (DM) candidate. In this work, we explore a sterile neutrino production mechanism thro…
Blast-frozen Dark Matter and Modulated Density Perturbations
Miha Nemevšek, Yue Zhang
First-order phase transitions (FOPT) are ubiquitous in beyond the Standard Model physics and leave distinctive echoes in the history of early universe. We consider a FOPT serving t…
Radiative Correction from Secret Neutrino Interactions and Implications for Neutrino-Scattering Experiments
Saeid Foroughi-Abari, Kevin J. Kelly, Yue Zhang
New, neutrinophilic mediators are one potential extension beyond the Standard Model of particle physics. Often, studies of neutrinophilic mediator consist of searching for direct e…
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…
BBN Constraint on Heavy Neutrino Production and Decay
Yu-Ming Chen, Yue Zhang
We explore the big-bang nucleosynthesis (BBN) constraint on heavy neutrino that is a mixture of gauge singlet fermion and active neutrinos in the Standard Model. We work in the min…
Enabling Strong Neutrino Self-interaction with an Unparticle Mediator
Saeid Foroughi-Abari, Kevin J. Kelly, Mudit Rai +1
Recent explorations of the cosmic microwave background and the large-scale structure of the universe have indicated a preference for sizable neutrino self-interactions, much strong…
