Energy spectrum of magnetic fields from electroweak symmetry breaking
This paper presents an analytical method and a new continuous simulation framework to study the energy spectrum of magnetic fields generated by inhomogeneous Higgs field configurations during electroweak symmetry breaking, bypassing the limitations of traditional lattice simulations.
Phenomenology of Vector Dark Matter produced by a First Order Phase Transition
This paper investigates how a first-order phase transition in a dark sector can significantly alter the relic abundance of scalar and vector dark matter compared to standard thermal freeze-out, providing specific mass predictions and associated gravitational wave signals for different transition temperatures.
Mass spectra of charged mesons and the quenching of vector meson condensation via exact phase-space diagonalization
Using an exact non-commutative phase-space framework within the two-flavor NJL model, this paper demonstrates that the mass follows the kinematic zero-point energy drift to preserve the Goldstone theorem, while the predicted tachyonic instability of the meson is quenched because magnetic catalysis raises the continuum threshold faster than Zeeman splitting can induce condensation.
Nucleon decays into one lepton plus two non-strange mesons
This paper uses a model-independent effective field theory approach to correlate two-body and three-body nucleon decay processes, resulting in significantly improved lifetime bounds for various lepton and non-strange meson decay modes compared to current PDG values.
\texttt{SWIM}: Stochastic Warm Inflation Module to generate and analyse Warm Inflationary power spectrum
The paper introduces **SWIM** (Stochastic Warm Inflation Module), a C++/Python-based numerical platform that enables the generation of fully numerical scalar power spectra for any warm inflation model and integrates with Cobaya to facilitate efficient parameter estimation against cosmological data using machine learning techniques.
Gravitational Wave Birefringence from Fuzzy Dark Matter
This paper investigates gravitational wave amplitude birefringence induced by the coupling of fuzzy dark matter to the Chern-Simons term, finding that the effect is characterized by a frequency-dependent enhancement/suppression of circular polarizations and a periodic time modulation reflecting the dark matter mass.
The need for a nonlocal expansion in general relativity
Inspired by insights from effective field theory and non-Abelian gauge theory, this contribution argues that the post-Newtonian approximation may fail for extended rotating bodies due to non-local angular momentum effects and proposes a novel effective field theory of general relativity to remedy this failure.
The High-Temperature Limit of the SM(EFT)
This paper derives the one-loop effective 3-dimensional Lagrangian for the high-temperature limit of the electroweak theory and the Standard Model effective field theory up to , providing a precise framework for studying the electroweak phase transition.
Consistent fitting in big bang nucleosynthesis analysis
This paper argues that the conventional method of fitting in Big Bang Nucleosynthesis (BBN) is inconsistent when dealing with negative deviations (), and proposes that such scenarios must instead account for the physical suppression of neutrino-driven reaction rates to avoid unphysical results.
