EFT Validity and Truncation Uncertainty from few Nuisance Parameters

This paper proposes an automation-friendly algorithm that utilizes the calculable O(Λ−4)\mathcal{O}(\Lambda^{-4}) contributions in SMEFT to model higher-order truncation uncertainties with a minimal set of nuisance parameters, thereby significantly reducing parameter counts and ensuring EFT validity by constraining bounds to kinematic regions where uncertainties are subdominant.

Studying baryon number transport dynamics via hyperon-kaon correlations in p+Aup + \mathrm{Au} collisions at sNN=20\sqrt{s_{_{\rm NN}}}=20, $39$ and $62$ GeV

This paper utilizes AMPT and UrQMD models to simulate hyperon-kaon correlations in p+Aup + \mathrm{Au} collisions at 20, 39, and 62 GeV, establishing a baseline without baryon junction mechanisms to test theories of baryon number transport and strange quark pair correlations.

Flipped rotating axion: Baryogenesis and Dark Matter

This paper proposes a mechanism where a spectator axion-like particle with a periodic non-minimal coupling to gravity undergoes a vacuum manifold flip at the end of non-oscillating inflation, enabling its subsequent rotation to simultaneously generate the baryon asymmetry via spontaneous baryogenesis and constitute dark matter, provided a specific non-minimal coupling strength prevents condensate fragmentation.

Neutrino mass constraints in the Schwarzschild-de Sitter black-hole dark energy model with ACT DR6 and DESI DR2 data

Using recent CMB, DESI, and supernova data, this study finds that the Schwarzschild-de Sitter black-hole dark energy model prefers a positive neutrino mass due to parameter correlations, yet the standard Λ\LambdaCDM model remains strongly favored over this alternative framework.

A Unified Dark Matter Explanation for B+ ⁣→K+ννˉ\boldsymbol{B^+ \!\to K^+ν\barν} and the Super-Kamiokande Antineutrino Excess

This paper proposes a unified UV-complete complex scalar dark matter model with a gauged U(1)Lμ−Lτ\text{U}(1)_{\textsf{L}_\mu-\textsf{L}_\tau} symmetry that simultaneously explains the Super-Kamiokande antineutrino excess and the Belle II B+→K+ννˉB^+ \to K^+ \nu\bar{\nu} branching fraction anomaly while reproducing the observed dark matter relic density.
