Small Cues, Big Consequences: Learning Pivotal Cues for Multimodal Meme Classification
Akshit Sharma, Prashant W. Patil
Memes often derive their harmful, hateful, or sarcastic meaning from small but decisive visual, textual, or cross-modal cues. Existing multimodal classifiers can miss such evidence…
Resonant neutrino flavor conversion within dark matter spikes
P. S. Bhupal Dev, Elisa Gaido, Alejandro Ibarra +1
We investigate how neutrino--dark matter (DM) interactions modify the flavor composition of high-energy neutrinos from active galactic nuclei (AGNs). Coherent forward scattering in…
Gamma-Ray Echo as a Probe of Supernova Neutrino Emission Anisotropy and Long-Baseline Effects
Garv Chauhan, Cecilia Lunardini, Yago Porto
During a core-collapse supernova (CCSN), the emitted electron antineutrino () burst initiates inverse beta decay (IBD) in the outer hydrogen layer of the stellar envelope.…
Ruling Out Spiky WIMP Dark Matter using Indirect Searches
Dibya S. Chattopadhyay, P. S. Bhupal Dev, Yago Porto
The dark matter (DM) density profile in the innermost region of the Galaxy remains an open question. In particular, while adiabatic growth of the supermassive black hole Sgr A$^\as…
Constraint on Pseudo-Dirac Neutrinos
Chee Sheng Fong, Yago Porto
After the electroweak symmetry breaking, we can write down two types of mass for the Standard Model neutrinos, Dirac or Majorana. It is often said that both types of mass cannot be…
Expected flavor composition of supernova neutrinos
Antonio Capanema, Yago Porto, Maria Manuela Saez
We revisit the flavor composition of neutrinos from core-collapse supernovae (SN), focusing on robust predictions that are insensitive to the poorly known dynamics of collective fl…
Scalar nonstandard neutrino interactions in galactic supernovae
Bhaskar Dutta, Aparajitha Karthikeyan, Nityasa Mishra +2
We analyze the prospects for studying scalar nonstandard interactions (SNSI) using the neutrino burst from a galactic supernova (SN). SNSI modifies the resonant flavor conversion a…
Neutrino Theory in the Precision Era
Asmaa Abada, Gabriela Barenboim, Toni Bertólez-Martínez +76
This document summarises discussions on future directions in theoretical neutrino physics, which are the outcome of a neutrino theory workshop held at CERN in February 2025. The st…
Signatures of quasi-Dirac neutrinos in diffuse high-energy astrophysical neutrino data
Kiara Carloni, Yago Porto, Carlos A. Argüelles +2
Although the sources of astrophysical neutrinos are still unknown, they are believed to be produced by a population of sources in the distant universe. Measurements of the diffuse,…
Non-Standard Interactions of Supernova Neutrinos and Mass Ordering Ambiguity at DUNE
Sudip Jana, Yago Porto
We show that non-standard neutrino interactions (NSI) can notably modify the pattern of resonant flavor conversion of neutrinos within supernovae and significantly impact the neutr…
Constraining the pseudo-Dirac nature of neutrinos using astrophysical neutrino flavor data
Chee Sheng Fong, Yago Porto
The three Standard Model neutrinos can have Majorana mass or strictly Dirac mass, but both scenarios are practically indistinguishable in neutrino oscillation experiments. If they…
Flavor composition of supernova neutrinos
Antonio Capanema, Yago Porto, Maria Manuela Saez
Predicting the flavor composition of neutrinos from supernovae is a challenging task, primarily due to the high neutrino densities at their core. In such an environment, neutrino s…
Flavor Matters, but Matter Flavors: Matter Effects on Flavor Composition of Astrophysical Neutrinos
P. S. Bhupal Dev, Sudip Jana, Yago Porto
We show that high-energy astrophysical neutrinos produced in the cores of heavily obscured active galactic nuclei (AGNs) can undergo strong matter effects, thus significantly influ…
New Resonances of Supernova Neutrinos in Twisting Magnetic Fields
Sudip Jana, Yago Porto
We investigate the effect of resonant spin conversion of the neutrinos induced by the geometrical phase in a twisting magnetic field. We find that the geometrical phase originating…
