Hep-Ph explores the fundamental forces that govern how particles interact and behave at the smallest scales imaginable. This field bridges the gap between theoretical predictions and experimental reality, helping scientists understand the building blocks of our universe without getting lost in complex mathematics. Whether investigating the Higgs boson or searching for new physics beyond current models, these studies push the boundaries of human knowledge about matter and energy.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper classifies the gravitational wave phenomenology of cosmic string networks with time-varying tension arising from moduli dynamics in string compactifications, providing concrete type IIB string theory examples and deriving general bounds on tension variation and spectral indices using Swampland constraints.
This paper investigates the generation of Dark Matter relic density via the freeze-in mechanism in a model featuring a heavy scalar leptoquark that mediates renormalizable interactions between Dark Matter and Standard Model particles, exploring the resulting parameter space to identify values consistent with observational constraints.
By fitting the Hagedorn temperature directly to lattice QCD data on net-baryon number susceptibility, this study demonstrates that a string-based model treating baryons as quark-diquark systems successfully reproduces a broad set of conserved charge fluctuations, thereby providing thermodynamic evidence for the quark-diquark structure of baryons in the confined phase of QCD.
This paper employs Quantum Fisher Information to demonstrate that long-baseline neutrino experiments possess significantly higher intrinsic quantum sensitivity to the mass-squared difference compared to the CP-violating phase and atmospheric mixing angle , while also revealing how matter effects and specific measurement strategies influence the extraction of this information.
This paper updates the viable parameter space for Affleck-Dine baryogenesis using recent CMB isocurvature constraints and demonstrates that primordial features in the inflaton sector can uniquely probe this high-energy mechanism by leaving correlated imprints on both curvature and baryon-density isocurvature perturbations.
This paper investigates the nonequilibrium hydrodynamic response of a one-dimensional Bose-Hubbard fluid to a propagating two-magnon bound state, demonstrating through matrix-product-state simulations that the coupling induces a dynamical backreaction which slows the bound state and generates distinct density wave patterns depending on whether the system is in the Mott or compressible regime.
Although the AXIS mission was not selected for implementation, its mature instrument design serves as a benchmark demonstrating that a future AXIS-like X-ray observatory could improve existing dark matter decay lifetime limits by up to an order of magnitude in the keV mass range.
This paper presents the first compelling experimental evidence for a Landau triangle singularity, identified as a distinct cusp-like structure at 1.564 GeV in the invariant mass spectrum from decays measured by BESIII, which aligns precisely with kinematic predictions and significantly improves the data fit.
This paper presents the first systematic analysis of power corrections in the factorization of leading-twist baryon quasi-distribution amplitudes, deriving an exact closed-form relation that resums target-mass corrections to all orders and explicitly constructing next-to-leading-twist operators to quantify these effects for future lattice QCD determinations.
This paper proposes a model where a non-invertible selection rule, realized through the gauging of a symmetry, suppresses flavor-violating portal couplings in lepton portal dark matter to achieve one-flavor dominance while remaining consistent with the PMNS mixing matrix and offering testable predictions for lepton flavor non-universality in boson decays.
