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 study demonstrates that neutron star observables in hybrid equation-of-state models retain significant sensitivity to the choice of low-density nuclear matter models at commonly adopted transition densities (), implying that lowering the transition density is necessary to minimize systematic uncertainties and achieve model-independent predictions.
This paper extends perturbative Gubser flow solutions to derive analytic nonlinear response relations for flow harmonics and , revealing that a mismatch between participant and reaction planes introduces a critical angular factor that can significantly alter the magnitude and even the sign of effective nonlinear response coefficients.
This paper reviews constraints on baryon inhomogeneities derived from deuterium abundance measurements, concluding that while current and future data leave electroweak baryogenesis largely unconstrained, they significantly limit the viability of various alternative baryogenesis scenarios.
Using 15 years of Fermi-LAT data and new eROSITA constraints, this study revises the GeV gamma-ray emission of the Vela Jr supernova remnant as primarily shell-like with minimal pulsar wind nebula contribution, and finds that a hybrid lepton-hadron model best explains the multi-wavelength spectrum, suggesting a hadronic origin for the GeV emission while the TeV emission remains predominantly leptonic.
This paper proposes a minimal radiative Dirac neutrino mass model stabilized by a non-invertible fusion rule from a gauging, which successfully generates one-loop neutrino masses, provides a viable bosonic dark matter candidate, and remains consistent with current lepton flavor violation and magnetic moment constraints.
This paper demonstrates that by imposing specific momentum correlations among Volkov states, a charged lepton in an electromagnetic plane wave can form a structured wavepacket whose probability-density peak travels at an arbitrary, tailored velocity independent of the field amplitude and the standard expectation value.
This paper employs non-relativistic effective field theory and the Keldysh-Schwinger formalism to self-consistently compute pair production and Sommerfeld-enhanced annihilation, demonstrating that this approach unitarizes the cross-section in a temperature-dependent manner while confirming vacuum results and revealing that bound states remain on-shell during out-of-equilibrium decay despite having Breit-Wigner spectral functions.
This paper introduces "SemiCharmTag," a novel tool for LHCb that utilizes secondary vertex hadron track tagging to effectively reject or isolate charm semileptonic backgrounds in dimuon Drell-Yan measurements at 13.6 TeV, significantly improving signal-to-background ratios while enabling the creation of unbiased charm-enriched samples.
This paper numerically demonstrates that false-vacuum decay between metastable honeycomb and stripe supersolid phases in a uniform dipolar gas is driven by bubble nucleation whose growth speed is limited by the slowest sound mode, establishing dipolar supersolids as a versatile platform for studying this phenomenon with direct real-space imaging capabilities.
This paper systematically compares HERWIG, PYTHIA, and SHERPA event generators for jet photoproduction in and $ep$ collisions, finding that while all provide decent descriptions of LEP and HERA data, achieving precision predictions for the future EIC requires a global refit of photon parton distributions and dedicated measurements to constrain non-perturbative parameters.
