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.”

Axion Domain Walls and Thermal Friction

Published:Dec 29, 2025 12:45
1 min read
ArXiv

Analysis

This paper addresses the challenges in accurately predicting axion dark matter abundance, a crucial problem in cosmology. It highlights the limitations of existing simulation-based approaches and proposes a new analytical framework based on non-equilibrium quantum field theory to model axion domain wall networks. This is significant because it aims to improve the precision of axion abundance calculations, which is essential for understanding the nature of dark matter and the early universe.
Reference

“The paper focuses on developing a new analytical framework based on non-equilibrium quantum field theory to derive effective Fokker-Planck equations for macroscopic quantities of axion domain wall networks.”

Axion Coupling and Cosmic Acceleration

Published:Dec 29, 2025 11:13
1 min read
ArXiv

Analysis

This paper explores the role of a \cPT-symmetric phase in axion-based gravitational theories, using the Wetterich equation to analyze renormalization group flows. The key implication is a novel interpretation of the accelerating expansion of the universe, potentially linking it to this \cPT-symmetric phase at cosmological scales. The inclusion of gravitational couplings is a significant improvement.
Reference

“The paper suggests a novel interpretation of the currently observed acceleration of the expansion of the Universe in terms of such a phase at large (cosmological) scales.”

Discovery Prospects for Photophobic Axion-like Particles at a 100 TeV Collider

Published:Dec 29, 2025 02:37
1 min read
ArXiv

Analysis

This paper investigates the potential for discovering heavy, photophobic axion-like particles (ALPs) at a future 100 TeV proton-proton collider. It focuses on scenarios where the diphoton coupling is suppressed, and electroweak interactions dominate the ALP's production and decay. The study uses detector-level simulations and advanced analysis techniques to assess the discovery reach for various decay channels and production mechanisms, providing valuable insights into the potential of future high-energy colliders to probe beyond the Standard Model physics.
Reference

“The paper presents discovery sensitivities to the ALP--W coupling g_{aWW} over m_a∈[100, 7000] GeV.”

    Two-Field ALP Dark Matter and Cosmic Birefringence

    Published:Dec 26, 2025 06:23
    1 min read
    ArXiv

    Analysis

    This paper investigates the implications of cosmic birefringence, a phenomenon related to the rotation of CMB polarization, for axion-like particle (ALP) dark matter models. It moves beyond single-field models, which face observational constraints due to the 'washout effect,' by exploring a two-field ALP model. This approach aims to reconcile ALP dark matter with observations of cosmic birefringence.
    Reference

    “The superposition of two ALP fields with distinct masses can relax the constraints imposed by the washout effect and reconcile with observations.”
