Revisiting One-Zero and Two-Zero Neutrino Mass Textures in Light of Recent Oscillation and Cosmological Data

This paper re-evaluates one-zero and two-zero neutrino mass textures against recent oscillation and cosmological data, finding that while several two-zero structures remain viable under CMB constraints alone, only the $A$ -series survives stricter CMB+BAO limits, and it further employs machine learning to analyze one-zero textures and their potential origin in non-invertible selection rules.

Electron-Ion Collision Environment: Distribution of Quark Spin and Orbital Angular Momentum

This theoretical study utilizes the Nambu--Jona-Lasinio model and light-front dressed quark model to calculate quark spin and orbital angular momentum distributions in proton and nuclear environments, introducing GTMD ratios between electron-proton and electron-ion collisions to quantify non-perturbative many-body nuclear density effects.

Leptogenesis and Low Reheating Temperatures

This paper demonstrates that in canonical type-I seesaw models with non-thermal inflaton decay, generalized Starobinsky potentials (specifically $V(\phi) \propto \phi^k$ with $k \geq 4$ ) enable successful leptogenesis at arbitrarily low reheating temperatures above the BBN bound, a scenario where standard matter-like reheating fails, due to kinematic shutoff effects that render the final baryon asymmetry primarily dependent on the inflaton-RHN coupling and CP-violation rather than RHN mass or decay rates.

Heavy quark coalescence probability in the presence of a potential

This study develops a phenomenological heavy quark potential based on the constituent quark model to demonstrate that the heavy quark coalescence probability remains close to unity at low momentum, provided that medium-induced modifications in the quark-gluon plasma are sufficiently moderate.

Optimal-Transport-Based Cell Resampling for Negative and Pathological Event Weights

This paper proposes using Optimal Transport-based metrics, such as the Energy Mover's Distance, to drive cell resampling algorithms that effectively mitigate negative and pathological event weights in LHC Monte Carlo simulations while reducing bias compared to existing techniques.

Examining hadronic resonance dynamics at energies available at the CERN Large Hadron Collider: Insights from EPOS4

This study utilizes the EPOS4 model to analyze hadronic resonance dynamics in LHC collisions, revealing how the hadronic phase lifetime increases with system size and how competing effects like rescattering, regeneration, and strangeness enhancement govern particle production across different transverse momentum regions.

Three-Loop QCD corrections to the production of a Higgs boson and a Jet

This paper presents the computation of three-loop QCD corrections to the scattering amplitude for Higgs boson and three-parton production in the generalized leading color limit, expressing the results in terms of multiple polylogarithms to enable precise phenomenological predictions for Higgs-plus-jet production at hadron colliders and Higgs decay to three jets at lepton colliders.

Phase transitions in scalarized topological AdS black holes

This paper investigates black hole scalarization induced by a charged scalar field in asymptotic AdS spacetimes with three distinct horizon topologies within the extended phase space, revealing that scalarization occurs at low temperatures for all cases, exhibits unique high-temperature domains and complex phase transitions in the spherical topology, and undergoes a pressure-driven transition from first-order to "cave-of-wind" style condensation across all geometries.

Pion generalized parton distributions at zero skewness

This paper systematically calculates the zero-skewness generalized parton distributions of the pion within a covariant Nambu–Jona-Lasinio model using proper time regularization, demonstrating excellent agreement with experimental data, lattice QCD simulations, and global QCD analyses while providing specific values for the pion's scalar, vector, and tensor charge radii.

Scale invariant radiative neutrino mass model

This paper proposes a scale-invariant radiative neutrino mass model with custodial symmetry, where the Coleman-Weinberg mechanism induces necessary mass scales, leading to a light MeV-scale right-handed neutrino that serves as dark matter and explains the baryon asymmetry via resonant leptogenesis.
