Low-energy neutrino responses for 71Ga by electron capture rates, charge exchange reactions and shell model calculations

This study evaluates the weak Gamow-Teller responses for low-lying states in ${}^{71}\mathrm{Ga}$ by combining experimental electron capture rates, corrected charge exchange reaction data, and shell model calculations, revealing that excited state contributions amount to approximately 4.2% of the ground state response and confirming that the Ga anomaly cannot be explained by uncertainties in these nuclear responses.

Resumming transverse observables for NNLO+PS matching in GENEVA

This paper presents a GENEVA framework for NNLO+PS matching of transverse observables by embedding N $^3$ LL $q_T$ resummation and introducing generalized $N$ -jettiness resummation up to NLL $'$ accuracy, demonstrated through a Higgs boson production generator in heavy-quark annihilation.

Matching HEFT and SMEFT in double and triple Higgs production from weak boson fusion

This paper establishes an analytical matching between SMEFT and HEFT effective field theories by equating scattering amplitudes for double and triple Higgs production via weak boson fusion, deriving relations between their coefficients and discussing their phenomenological implications for collider physics.

All-order prescription for facet regions in massless wide-angle scattering

This paper presents a novel all-order momentum-space prescription for systematically identifying facet regions in massless wide-angle scattering using a combination of graph theory and convex geometry, thereby resolving long-standing questions about region determination in asymptotic expansions and revealing the non-distributive lattice structure of momentum modes.

Nucleon Parton Distribution Functions from Boosted Correlations in the Coulomb gauge

This paper presents the first exploratory lattice QCD calculation of nucleon unpolarized, helicity, and transversity parton distribution functions using a novel Coulomb gauge boosted-correlator method within Large-Momentum Effective Theory, demonstrating that the approach yields results consistent with global analyses and phenomenology while highlighting specific challenges with excited-state contamination in imaginary matrix elements.

Matter Flavor Conversion Mediated by Pseudo-Sterile States as the Possible Origin of Neutrino Oscillation Anomalies

This paper proposes a 3+1 neutrino model where sterile neutrinos interact via a novel, density-dependent matter potential to simultaneously resolve long-standing oscillation anomalies across diverse energy scales, including tensions between NOvA and T2K, the Super-Kamiokande atmospheric excess, and IceCube high-energy data, while remaining consistent with disappearance searches and testable by KATRIN.

Insight on confinement from the QCD effective charge

This paper interprets QCD confinement as the long-distance suppression of parton propagators, deriving a specific exponential decay behavior from the analytic structure of the physical effective charge $\alpha_{g_1}$ within the framework of holographic light-front QCD.

Closed Universe, Quantum Entanglement and Observers

This paper unifies three distinct models of observers in closed quantum gravity universes by demonstrating that they all emerge from spontaneously broken diffeomorphisms and Goldstone bosons within the "Massive Islands" paradigm, thereby revealing the graviton mass as a feature of the quantum state and enabling observers to detect global symmetries.

Primordial black holes as a natural consequence of scale-invariance

This paper proposes that a scale-invariant $U(1)$ gauge theory with a nonminimal Higgs-gravity coupling naturally generates large curvature perturbations at the end of thermal inflation, leading to the formation of primordial black holes accompanied by correlated gravitational wave signatures from both scalar-induced and cosmic-string mechanisms.

Neutrino flavor conversion alters the lepton-emission self-sustained asymmetry in core-collapse supernovae

By solving neutrino equations of motion in a two-dimensional half-annulus model, this study demonstrates that flavor conversion driven by collisional, fast, and slow instabilities significantly enhances the Lepton-number Emission Self-sustained Asymmetry (LESA) dipole by 5–10% in core-collapse supernovae, independent of neutrino mass ordering.
