Bounds on SMEFT affecting multi gauge and Higgs-gauge couplings using two and three body spin correlations in $e^-e^+\to 3l2j\slashed{E}$ process

This paper utilizes beam polarization, spin correlations, and machine learning techniques to constrain dimension-6 SMEFT Wilson coefficients affecting multi-gauge and Higgs-gauge couplings in $e^-e^+ \to 3l2j\slashed{E}$ events at future electron-positron colliders, demonstrating that Vector Boson Scattering-like processes provide tighter constraints on $c_W$ and $c_B$ while WWZ production dominates limits on the remaining couplings.

Leptogenesis from Dark Matter Coannihilation

This paper proposes a minimal extension of the type-I seesaw model involving a $Z_2$ -symmetric dark sector, where the co-annihilation of dark matter with a singlet fermion generates a net lepton asymmetry at the TeV scale, thereby linking successful leptogenesis directly to the observed dark matter abundance.

Monojet and direct detection constraints on real scalar dark matter: EFT and a simple UV completion

This paper analyzes constraints on real scalar dark matter by comparing LHC monojet searches with direct detection limits using both an effective field theory approach and a specific UV completion involving vector-like quarks, identifying parameter regions where collider data provides crucial complementary bounds.

Constraining a de Broglie--Bohm quantum bounce cosmology with Planck data

This paper presents a singularity-free de Broglie–Bohm quantum bounce cosmology that is strongly compatible with Planck 2018 CMB data, places a stringent upper bound on the bounce scale, and offers a potential mechanism to mitigate the $H_0$ - $\sigma_8$ tension through a unique scale-dependent anticorrelation.

The Gravitational Aspect of Information: The Physical Reality of Asymmetric "Distance"

This paper demonstrates that a constrained Brownian bridge evolves along an m-geodesic on the statistical manifold of Gaussian distributions, thereby establishing a physical realization of information geometry where random processes follow informational straight trajectories and highlighting the fundamental physical role of asymmetric informational distance.

Tensor form factors of the $Δ^+$ baryon induced by isovector and isoscalar currents in QCD

This paper presents the full Lorentz decomposition of the tensor form factors for the $\Delta^+$ baryon induced by both isovector and isoscalar currents, revealing distinct contributions from up and down quark components that reflect the baryon's internal structure and spin distribution.

Scaling Properties of Two-Particle-Two-Hole Responses in Asymmetric Nuclei for Neutrino Scattering within the Relativistic Mean-Field Framework

This paper presents a systematic relativistic mean-field analysis of two-particle-two-hole meson-exchange current contributions across 17 asymmetric nuclei, proposing a novel scaling prescription that accurately models nuclear responses for neutrino event generators while benchmarking against electron-scattering data.

Diffusion Models for SU(2) Lattice Gauge Theory in Two Dimensions

This paper demonstrates that score-based diffusion models, utilizing quaternion parameterization and physics-conditioned sampling, can accurately generate SU(2) lattice gauge configurations across varying coupling strengths and lattice sizes without retraining, achieving results consistent with exact analytical predictions.

Three-loop QCD+QED corrections to on-shell quark renormalization

This paper presents the complete three-loop mixed QCD and QED corrections to on-shell quark mass and wave-function renormalization constants, deriving the corresponding relations between pole, $\overline{\text{MS}}$ , and trace-anomaly subtracted $\sigma$ masses, as well as the quark-mass anomalous dimension.

Dark Glueball Direct Detection

This paper proposes a viable glueball dark matter candidate arising from a confined Yang-Mills sector coupled to the Standard Model via vector-like fermion portals, developing a non-perturbative effective field theory framework that predicts a steeply scaling spin-independent scattering cross-section ( $\sigma_{\rm SI}\propto \Lambda_D^{2.15} m_\psi^{-8}$ ) within the sensitivity reach of current and next-generation xenon direct-detection experiments.
