Universal Seesaw Pati-Salam Model with Strong CP Solution

Published:Dec 31, 2025 18:27
1 min read
ArXiv

Analysis

This paper proposes a novel Pati-Salam model that addresses the strong CP problem without relying on an axion. It utilizes a universal seesaw mechanism to generate fermion masses and incorporates parity symmetry breaking. The model's simplicity and the potential for solving the strong CP problem are significant. The analysis of loop contributions and neutrino mass generation provides valuable insights.
Reference

“The model solves the strong CP problem without the axion and generates fermion masses via a universal seesaw mechanism.”

Loop-Level Lepton Flavor Violation and Diphoton Signals in the Minimal Left-Right Symmetric Model

Published:Dec 31, 2025 18:14
1 min read
ArXiv

Analysis

This paper explores the lepton flavor violation (LFV) and diphoton signals within the minimal Left-Right Symmetric Model (LRSM). It investigates how the model, which addresses parity restoration and neutrino masses, can generate LFV effects through the mixing of heavy right-handed neutrinos. The study focuses on the implications of a light scalar, H3, and its potential for observable signals like muon and tauon decays, as well as its impact on supernova signatures. The paper also provides constraints on the right-handed scale (vR) based on experimental data and predicts future experimental sensitivities.
Reference

“The paper highlights that the right-handed scale (vR) is excluded up to 2x10^9 GeV based on the diphoton coupling of H3, and future experiments could probe up to 5x10^9 GeV (muon experiments) and 6x10^11 GeV (supernova observations).”

Lepton Flavor Violation in Supersymmetric Seesaw Model

Published:Dec 30, 2025 11:49
1 min read
ArXiv

Analysis

This paper investigates lepton flavor violation (LFV) within the Minimal R-symmetric Supersymmetric Standard Model with Seesaw (MRSSMSeesaw). It's significant because LFV is a potential window to new physics beyond the Standard Model, and the MRSSMSeesaw provides a specific framework to explore this. The study focuses on various LFV processes and identifies key parameters influencing these processes, offering insights into the model's testability.
Reference

“The numerical results show that the non-diagonal elements involving the initial and final leptons are main sensitive parameters and LFV sources.”

A4-Symmetric Double Seesaw for Neutrino Masses and Mixing

Published:Dec 30, 2025 10:35
1 min read
ArXiv

Analysis

This paper proposes a model for neutrino masses and mixing using a double seesaw mechanism and A4 flavor symmetry. It's significant because it attempts to explain neutrino properties within the Standard Model, incorporating recent experimental results from JUNO. The model's predictiveness and testability are highlighted.
Reference

“The paper highlights that the combination of the double seesaw mechanism and A4 flavour alignments yields a leading-order TBM structure, corrected by a single rotation in the (1-3) sector.”

Minimal A4 Seesaw Model with Testable Neutrino Mass Sum Rules

Published:Dec 26, 2025 19:00
1 min read
ArXiv

Analysis

This paper presents a flavor model using A4 symmetry and a type-II seesaw mechanism. The key significance lies in its ability to predict the absolute neutrino mass spectrum based on a sum rule, linking it to lepton mixing parameters and potentially observable phenomena like neutrinoless double beta decay. The model's constrained nature makes it experimentally testable, offering a framework to connect neutrino properties with lepton mixing and lepton-number-violating processes.
Reference

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