This paper investigates the phenomenology of a light charged Higgs boson ($110 < m_{H^\pm} < 170Z'$ boson, analyzing its production mechanisms at the LHC, current experimental constraints from ATLAS and CMS, and its interplay with dark matter properties.
This paper proposes a Standard Model extension featuring three non-zero hypercharge triplets under a gauge symmetry, demonstrating that the model can simultaneously satisfy vacuum stability up to the Planck scale, perturbative unitarity up to $10^{12}$ GeV, and a strongly first-order electroweak phase transition with detectable gravitational wave signatures at LISA and BBO.
This paper proposes a method to accelerate multijet event generation for LHC analyses by employing neural-network surrogates within a two-stage rejection-sampling algorithm, achieving over a tenfold reduction in generation time for Z+jets processes at the HL-LHC compared to the baseline Sherpa generator.
This paper introduces FLARE, an open-source, b2luigi-powered workflow orchestration tool designed to automate and manage the full data processing and Monte Carlo generation lifecycle for FCCee analyses within the Key4HEP stack.
This paper presents a fully analytic hydrodynamic model incorporating a lattice-QCD-consistent equation of state to describe thermal photon production across the quark-hadron transition, demonstrating good agreement with PHENIX experimental data for Au+Au collisions at GeV and enabling the investigation of initial temperature centrality dependence.
This study combines 14 years of Fermi-LAT and 10 years of H.E.S.S. observations of the galactic center to establish stringent constraints on dark matter annihilation into gamma-ray lines, demonstrating that Fermi-LAT provides the tightest limits for masses below 300 GeV while H.E.S.S. dominates for masses above 1 TeV, collectively probing energy scales up to 10–20 TeV.
The JETSCAPE Collaboration employs Bayesian Inference with Active Learning to determine the jet transport parameter in the Quark-Gluon Plasma by simultaneously analyzing inclusive hadron and jet suppression data from RHIC and LHC, revealing systematic tensions that offer new insights into jet transport physics.
By analyzing 2693 rotation-curve measurements from 153 SPARC galaxies within a unified radial framework defined by baryonic acceleration, the study reveals a galaxy-independent dark-matter halo structure characterized by a universal density profile (), a linear mass growth with radius, and a constant rotation velocity beyond a specific scaled distance.
This paper demonstrates that the Circular Electron Positron Collider (CEPC) can efficiently test the 95 GeV scalar hypothesis in the Higgsstrahlung channel by identifying 210 GeV as the optimal center-of-mass energy and utilizing deep neural networks to significantly reduce the luminosity required for discovery and precision measurement.
This paper investigates the formation of primordial black holes in ultra-slow-roll inflation scenarios with a sharp transition, revealing through numerical simulations that while both vacuum bubble and adiabatic perturbation channels contribute, the latter dominates the mass function by a factor of $10100$ and is primarily driven by mean profiles.
Using a potential quark model with the Gaussian expansion method and real scaling technique, this study finds no evidence for a compact or $3/2^-P_{c\bar{c}s}^0\Xi_c\bar{D}$ hadronic molecule.
This paper investigates the spin-parity assignments of hidden charm pentaquark states within a baryon-meson molecular framework using the Gursey-Radicati mass formula and magnetic moment calculations, identifying specific quantum numbers for observed candidates like , , , and while demonstrating that magnetic moments serve as a valuable observable for refining future quantum-number identification.
This paper proposes that if neutron star mergers trigger a first-order quantum chromodynamics phase transition, the resulting bubble nucleation and dynamics would generate distinctive megahertz-range gravitational waves, offering a new observational window for future detectors.
This paper re-evaluates Standard Model vacuum stability using high-order perturbations and precise parameters to show that improved measurements of the top mass and strong coupling could confirm stability at the $5\sigma$ level, while also exploring viable singlet scalar extensions that remain stable up to the Planck scale and predicting significant deviations in Higgs couplings testable at current and future colliders.
This paper reaffirms the robustness of strong experimental constraints on light neutralino thermal dark matter within the phenomenological MSSM, explores the impact of light staus and non-standard cosmology, and proposes machine learning-optimized benchmarks for future LHC Run-3 searches.
This paper advocates for a Bayesian statistical framework based on timescale analysis to derive the most rigorous constraints on ultralight boson masses and self-interactions from black hole spin measurements, demonstrating its application to both stellar-mass and supermassive black holes while highlighting the need for standardized data sharing in the field.
This paper proposes and validates a Pearson correlation between spectator and charged-particle forward-backward asymmetries as a robust, data-driven observable to constrain models of preferential emission and spectator breakup dynamics in heavy-ion collisions.
This study employs a two-fluid formalism and Bayesian analysis of multimessenger data to investigate how linear and quadratic scalar and vector dark matter interactions influence the structure, compactness, and equation of state of dark matter admixed neutron stars, revealing that vector repulsion and quadratic scalar couplings significantly alter stellar properties compared to standard models.
This paper reviews the analytically derived phenomenon of spontaneous magnetization in quark-gluon plasma at high temperatures, where color and usual magnetic fields are simultaneously generated and stabilized by an condensate, potentially offering observable signals for QGP creation in heavy ion collisions.
This paper employs QCD sum rules to systematically analyze D-wave charmonium states, predicting masses that align with recent experimental observations of , , and while also estimating the mass of the yet-unobserved state.
