Modular Flavor Symmetry for Lepton Textures

Published:Dec 31, 2025 11:47
1 min read
ArXiv

Analysis

This paper explores a specific extension of the Standard Model using modular flavor symmetry (specifically S3) to explain lepton masses and mixing. The authors focus on constructing models near fixed points in the modular space, leveraging residual symmetries and non-holomorphic modular forms to generate Yukawa textures. The key advantage is the potential to build economical models without the need for flavon fields, a common feature in flavor models. The paper's significance lies in its exploration of a novel approach to flavor physics, potentially leading to testable predictions, particularly regarding neutrino mass ordering.
Reference

The models strongly prefer the inverted ordering for the neutrino masses.

Analysis

This paper explores an extension of the Standard Model to address several key issues: neutrino mass, electroweak vacuum stability, and Higgs inflation. It introduces vector-like quarks (VLQs) and a right-handed neutrino (RHN) to achieve these goals. The VLQs stabilize the Higgs potential, the RHN generates neutrino masses, and the model predicts inflationary observables consistent with experimental data. The paper's significance lies in its attempt to unify these disparate aspects of particle physics within a single framework.
Reference

The SM+$(n)$VLQ+RHN framework yields predictions consistent with the combined Planck, WMAP, and BICEP/Keck data, while simultaneously ensuring electroweak vacuum stability and phenomenologically viable neutrino masses within well-defined regions of parameter space.

The model's sum rule fully determines the absolute neutrino mass spectrum, and the model provides a tightly constrained and experimentally testable framework.

Analysis

This paper investigates the potential for detecting gamma-rays and neutrinos from the upcoming outburst of the recurrent nova T Coronae Borealis (T CrB). It builds upon the detection of TeV gamma-rays from RS Ophiuchi, another recurrent nova, and aims to test different particle acceleration mechanisms (hadronic vs. leptonic) by predicting the fluxes of gamma-rays and neutrinos. The study is significant because T CrB's proximity to Earth offers a better chance of detecting these elusive particles, potentially providing crucial insights into the physics of nova explosions and particle acceleration in astrophysical environments. The paper explores two acceleration mechanisms: external shock and magnetic reconnection, with the latter potentially leading to a unique temporal signature.
Reference

The paper predicts that gamma-rays are detectable across all facilities for the external shock model, while the neutrino detection prospect is poor. In contrast, both IceCube and KM3NeT have significantly better prospects for detecting neutrinos in the magnetic reconnection scenario.
