This paper presents a comprehensive analysis of a supersymmetric SO(10) model where non-thermal leptogenesis explains the baryon asymmetry, yielding specific predictions for neutrino masses, the CP-violating phase , and the neutrinoless double beta decay parameter that remain consistent with JUNO's latest reactor neutrino oscillation data.
This paper presents a revised calculation of the complete non-local sub-leading contribution to the inclusive decay by removing the previously subtracted local Voloshin term, thereby addressing the high correlation between uncertainties and significantly impacting the estimated range of this contribution.
This theoretical study predicts the existence of well-isolated, deeply bound atoms with narrow widths and demonstrates that reactions on light nuclei are a highly effective method for observing these states as discrete peaks, thereby offering new insights into -nucleus interactions.
This study develops a rigorous, nonperturbative framework to quantify how mirror birefringence and polarization misalignment degrade sensitivity in axion-like particle searches, revealing that while misalignment effects can be mitigated through postselection, birefringence introduces a distinct high-mass resonance peak that necessitates careful consideration in high-precision optical-cavity experiments.
This paper introduces a generative framework based on denoising diffusion to perform model-independent, non-parametric reconstruction of proton gravitational form factors from sparse and noisy data, enabling robust extraction of chiral low-energy constants and the nucleon D-term across the full kinematic range.
This paper demonstrates that shock-induced density and temperature perturbations in core-collapse supernovae and neutron star mergers can overcome electron mass damping to sustain the chiral plasma instability and generate substantial ohmic heating via the chiral magnetic effect.
This study investigates the meson as a molecular state by calculating its decay partial widths, finding that while the Weinberg criterion underestimates the total width, adjusting the coupling constant allows the model to fit experimental data and suggests that current conflicting results do not yet rule out this molecular assignment.
This paper employs Evolutionary Strategies augmented with Novelty Reward to identify viable Z3-symmetric 3-Higgs Doublet Model dark matter candidates with mass-degenerate WIMPs across two distinct mass regimes, successfully satisfying theoretical and experimental constraints while revealing the challenges of navigating the model's non-convex parameter space.
This paper generalizes the jet transport coefficient to a Lorentz-covariant diffusion tensor to describe momentum broadening in out-of-equilibrium media, revealing new energy-momentum correlations and demonstrating that non-equilibrium corrections can either enhance or reduce broadening depending on the initial distribution.
This paper proposes a minimal multi-TeV quark-lepton unification framework with inverse seesaw neutrino masses, analyzes current experimental constraints on lepton flavor violation, and demonstrates that upcoming conversion experiments at Fermilab are crucial for testing this theory.
This paper proposes a scenario where grand unified theory breaking produces quasi-stable cosmic strings bounded by superheavy magnetic monopoles, which can collapse to yield an observable monopole density and emit high-frequency gravitational waves detectable by current and future experiments.
This paper presents a parameter-economical, unified quark-diquark effective mass framework calibrated on baryon spectroscopy and meson splittings to systematically predict the spectra of heavy tetraquarks and pentaquarks while naturally incorporating heavy-quark spin and flavor symmetries.
This paper demonstrates that the orbital eccentricity of massive black hole binaries significantly enhances LISA's parameter estimation capabilities, leading to a substantial increase in the number of bright standard sirens and resulting in markedly tighter cosmological constraints on parameters such as the Hubble constant and dark energy.
This paper summarizes the achievements of the MexNICA Collaboration, established in 2016 to coordinate Mexican participation in the MPD-NICA experiment at JINR, highlighting their contributions to the development of the miniBeBe trigger detector and advances in phenomenological and theoretical studies of the baryon-rich QCD phase diagram.
By employing multiparticle factorization and soft kinematics, this paper demonstrates that the infinite tower of higher-spin string excitations imposes such rigid constraints that the bosonic string's Regge intercept is uniquely fixed and specific deformations of superstring amplitudes are strictly forbidden by unitarity.
This paper proposes a covariant orbital-spin decomposed amplitude using massive canonical-spinor variables to streamline partial wave analysis of complex decay chains, a method validated by consistent results in the TF-PWA framework for the decay.
This paper demonstrates that while BPS geodesics with enhanced symmetry remain unchanged in the scattering of multiple Abelian-Higgs vortices, the excitation of massive bound modes introduces forces that significantly deform generic vortex trajectories and enhance chaotic behavior in the final state.
This paper classifies the distinct domain walls and calculates their tensions arising from the degenerate minima of scalar potentials invariant under the symmetry and its subgroups and , with and without imposed CP symmetries.
This paper investigates gravitational reheating in the Starobinsky model within the Jordan frame, demonstrating that particle production driven by Ricci scalar oscillations leads to a reheating temperature of approximately $2 \times 10^9$ GeV and highlighting how quantum effects can yield distinct microphysical interpretations and quantitative predictions compared to the Einstein frame.
This study demonstrates that self-interacting dark matter models, particularly those with large cross-sections, can explain the diverse dark matter density profiles of Milky Way ultra-faint dwarf galaxies by showing that most have undergone gravothermal collapse accelerated by tidal stripping.
