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 investigates the discovery potential of doubly-charged bileptons at the High-Luminosity LHC through direct pair production and heavy-quark-mediated channels, demonstrating that the latter offers significantly enhanced sensitivity capable of achieving a discovery for heavy quark masses up to 2.5 TeV and bilepton masses up to 2 TeV due to a distinctive, background-free four-lepton signature.
This paper proposes that accretion-induced collapses of rapidly-rotating, highly magnetized white dwarfs can generate magnetically-dominated relativistic outflows capable of accelerating heavy nuclei to ultra-high energies, potentially accounting for the observed flux of ultra-high-energy cosmic rays.
This paper utilizes the MC-CGC event generator to demonstrate that LHCb data favors HERA-constrained initial conditions for the rcBK evolution equation and that the dense-dense factorization framework better describes mid-rapidity particle production than the dilute-dense DHJ approach, while also providing predictions for future ALICE FoCal measurements.
This paper proposes that in a left-right weak interaction model, baryon and lepton asymmetries arise during the hadronization of quark-gluon plasma due to CP-violating differences in neutron and antineutron lifetimes caused by right-handed vector boson mixing, while sterile neutrinos account for dark matter and carry a compensating lepton asymmetry.
This paper investigates how accretion on primordial black holes (PBHs) prolongs early matter domination and shifts Big Bang nucleosynthesis constraints on PBH reheating scenarios—derived from isocurvature-induced gravitational waves and merger limits—towards smaller formation masses and initial abundances, with gravitational wave constraints proving more stringent than merger constraints.
This paper demonstrates that for a CFT on a flat open solid torus, the two-point function and disjoint entanglement entropy are exactly paired with finite bulk geodesics and entanglement wedge cross-sections, respectively, without requiring large , strong coupling, or heavy operators, thereby revealing a broader exact-pair structure in AdS/CFT beyond standard singular limits.
This paper investigates front propagation in an inhomogeneous model, demonstrating that while standard kink-based effective descriptions work well, a modified effective model is required to accurately capture the dynamics of half-kinks representing the decay of unstable states.
This paper presents a numerical study of MRW-type unintegrated double parton distribution functions constructed from non-factorized GS09 collinear DPDFs, comparing the performance and characteristics of double modified KMRW, double virtuality ordered MRW, and a normalization-matched variant to analyze their transverse momentum dependence, normalization properties, and sensitivity to longitudinal correlations.
This paper presents a comprehensive study of inclusive charm and bottom quark pair production cross sections across a wide range of collision energies using next-to-next-to-leading-order (NNLO) calculations with the new MaunaKea code, demonstrating that these advanced predictions significantly enhance accuracy and reduce theoretical uncertainties compared to previous NLO results, thereby achieving agreement with experimental data and offering valuable constraints on gluon density and the bottom-quark mass.
This paper investigates the Sudakov form factor and four-point scattering amplitude in planar SYM on the Coulomb branch, identifying a novel scaling limit where a "walking" anomalous dimension interpolates between the cusp and octagon anomalous dimensions and proposing an all-loop form for this behavior that depends on new unknown functions of the 't Hooft coupling.
