Astrophysical neutrinos are excellent probes of astroparticle physics and high-energy
physics. With energies far beyond solar, supernovae, atmospheric, and accelerator …

Do neutrinos have sizable self-interactions? They might. Laboratory constraints are weak, so
strong effects are possible in astrophysical environments and the early Universe …

A bstract Non-standard neutrino interactions with a massive boson can produce the bosons
in the core of core-collapse supernovae (SNe). After the emission of the bosons from the SN …

Protoneutron stars formed during core-collapse supernovae are hot and dense
environments that contain a sizable population of muons. If these interact with new long …

A bstract We propose a leptoquark model with two scalar leptoquarks\({S} _1\left (\overline
{3}, 1,\frac {1}{3}\right)\) and\({\tilde {R}} _2\left (3, 2,\frac {1}{6}\right)\) to give a combined …

We explore a self-interacting neutrino cosmology in which neutrinos experience a delayed
onset of free-streaming. We use the effective field theory of large-scale structure (LSS) to …

A cosmological scenario in which the onset of neutrino free streaming in the early Universe
is delayed until close to the epoch of matter-radiation equality has been shown to provide a …

We use data from the Atacama Cosmology Telescope (ACT) DR4 to search for the presence
of neutrino self-interaction in the cosmic microwave background. Consistent with prior works …

In this paper we introduce a light Dirac particle ψ as thermal dark matter candidate in a U (1)
L μ− L τ model. Together with the new gauge boson X, we find a possible parameter space …

Thermal MeV neutrino emission from core-collapse supernovae offers a unique opportunity
to probe physics beyond the Standard Model in the neutrino sector. The next generation of …
