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.

This paper presents exact analytic solutions for the linear dynamics of a two-field inflationary system with arbitrary entropy mass and interaction strength, providing closed-form expressions for the primordial power spectrum that bridge weakly and strongly coupled regimes and enabling future analytic studies of multifield observables like non-Gaussianity.
This paper investigates the low-, low- behavior of the proton's gluon distribution by modeling the photoabsorption cross section via two-gluon exchange to derive a reliable leading-order result through modified DGLAP evolution starting from GeV.
This paper investigates how Earth's matter effects and the finite momentum of axion dark matter influence experimental searches, finding that while canonical axion models remain largely unaffected, lighter axions with stronger couplings may experience reduced field values but enhanced spatial gradients, significantly altering detection sensitivity.
The paper argues that the absence of a hard-spectrum signal in the H.E.S.S. electron-positron flux implies that every nearby energetic pulsar must be surrounded by a region of inhibited diffusion, which traps high-energy particles and ensures all such pulsars are detectable as multi-wavelength sources.
This paper proposes that interactions between hidden sector particles and neutron star nucleons can overcome energy barriers to trigger deconfinement phase transitions, potentially converting neutron stars into black holes or gamma-ray bursts, thereby allowing the observed existence of ancient neutron stars to set constraints on dark matter interactions and nucleon decay lifetimes that are orders of magnitude stricter than terrestrial limits.
By employing a neural network simulation-based inference approach to jointly analyze spatial and spectral data, this study demonstrates that the Galactic Center Excess is consistent with a diffuse dark matter signal or an exceptionally large population of dim point sources, challenging earlier conclusions that favored a smaller number of brighter sources.
This paper proposes a 2-Higgs Doublet Model Type-I framework with a softly broken symmetry to simultaneously explain the 650 GeV excess at the LHC and the 95 GeV anomalies in , , and channels from LEP and LHC data through the production of a 650 GeV pseudoscalar decaying into a 125 GeV Higgs and a Z boson, alongside a 95 GeV scalar state, achieving a combined significance of .
This paper proposes a novel fibre inflation model within the perturbative large volume scenario that utilizes base modulus redefinitions and various string corrections to achieve inflationary parameters consistent with ACT data while simultaneously incorporating a quintessence sector to explain both early- and late-time cosmic acceleration.
This paper constructs a generalized second-order relativistic magnetohydrodynamics framework using Zubarev's nonequilibrium statistical operator to derive all dissipative tensors and Kubo formulas for a parity- and charge-conjugation-symmetric magnetized plasma, while extending the formalism to include nonlocal contributions.
This paper establishes a universal geometric framework linking the synchronized multivaluedness observed in black hole phase transitions to a three-sheeted covering structure arising from two non-degenerate critical points in the temperature function, thereby providing a rigorous classification scheme and a unified perspective on black hole thermodynamics and dynamics.
