Energy Dependence of Flavor Instabilities Stemming from Crossings in the Neutrino Flavor Lepton Number Angular Distribution Open
In core-collapse supernovae and neutron star mergers, the neutrino density is so large that neutrino-neutrino refraction can lead to flavor conversion, if a zero-crossing is present in the neutrino flavor lepton number (FLN) angular distri…

Effects of quantum decoherence in a future supernova neutrino detection Open
Quantum decoherence effects in neutrinos, described by the open quantum systems formalism, serve as a gateway to explore potential new physics, including quantum gravity. Previous research extensively investigated these effects across vari…

SN1987A neutrino burst: limits on flavor conversion Open
In this paper, we revisit the SN1987A neutrino data to see its constraints on flavor conversion. We are motivated by the fact that most works that analyze this data consider a specific conversion mechanism, such as the MSW (Mikheyev–Smirno…

Open-Source Numerical Solver for Neutrino Collective Effects -- I: Isotropic Neutrino Gas Open
In this paper, we introduce a new open-source code to find numerical solutions for the neutrino evolution considering neutrino-neutrino interactions, which result in the so-called collective effects. We first describe the theoretical backg…

Measurement of the -Ar total hadronic cross section at the LArIAT experiment Open
We present the first measurement of the negative pion total hadronic cross section on argon in a restricted
\nphase space, which we performed at the Liquid Argon In ATestbeam (LArIAT) experiment. All hadronic
\nreaction channels, as well a…

Neutrino–(anti)neutrino forward scattering potential for massive neutrinos at low energies Open
In this work, we calculate the expression for the potential due to neutrino–(anti)neutrino forward scattering at low energies [Formula: see text] for ultra-relativistic massive neutrinos [Formula: see text], a representative regime within …

Low-Energy Physics in Neutrino LArTPCs Open
In this white paper, we outline some of the scientific opportunities and challenges related to detection and reconstruction of low-energy (less than 100 MeV) signatures in liquid argon time-projection chamber (LArTPC) detectors. Key takeaw…

Machine learning applied to multifrequency data in astrophysics: blazar classification Open
The study of machine learning (ML) techniques for the autonomous classification of astrophysical sources is of great interest, and we explore its applications in the context of a multifrequency data-frame. We test the use of supervised ML …
