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 demonstrates that electromagnetic probes, specifically direct photons and dileptons, serve as sensitive indicators of the interplay between hard minijets and the quark-gluon plasma by revealing measurable effects from minijet-induced modifications to the spacetime evolution of the medium that are otherwise obscured in hadronic observables.
This paper demonstrates that a novel, model-independent method for extracting continuous decay amplitudes in processes remains robust and effective when applied to realistic experimental data containing non-factorising detection efficiencies and backgrounds, thereby enabling broader kinematic studies and improved sensitivity to new physics.
Motivated by anomalies in and , this paper presents an SMEFT analysis predicting that New Physics could enhance branching ratios by several orders of magnitude, making them accessible to future LHCb, CMS, and Belle II experiments while providing a crucial method to distinguish between different New Physics scenarios.
This paper presents the latest results from the MUSES collaboration using the 3+1D relativistic viscous hydrodynamics code CCAKE, enhanced with numerical improvements like "glass" initial conditions and adaptive smoothed particle hydrodynamics, to dynamically probe the QCD critical point and quantify its interplay with beam energy and rapidity range within the context of STAR's Beam Energy Scan II data.
This paper interprets a recent high-recoil nuclear event observed by the LUX-ZEPLIN experiment through two supersymmetric scenarios: an elastic scattering model involving a bino- or singlino-like neutralino with specific Higgsino asymmetry, and an inelastic scattering model featuring a pseudo-Dirac Higgsino, both of which predict distinct recoil spectra that can be distinguished from the candidate signal.
This paper utilizes an effective Lagrangian approach combined with transport simulations to predict that the J-PARC E16 experiment can observe a signal of - mixing, indicative of partial chiral symmetry restoration, with approximately 2.5 significance using planned Run2 statistics.
This paper introduces a resummed hydrodynamic scheme that enforces non-linear causality conditions to constrain viscous stress tensors within tunable limits, demonstrating through event-by-event simulations of Pb+Pb and p+Pb collisions that this approach quantifies theoretical uncertainties in final-state flow observables while recovering standard second-order theories in the small-viscosity limit.
This paper presents a systematic comparison of the GoSam+Whizard and POWHEG-BOX Monte Carlo tools for simulating electroweak Higgs boson pair production via vector boson fusion with two jets, providing cross sections and distributions for Standard Model and beyond scenarios while evaluating the validity of the VBF approximation in the presence of anomalous couplings.
This paper implements a finite energy constraint in the dipole picture of deep inelastic scattering by limiting the invariant mass of the produced partonic system, demonstrating that this effect significantly reduces cross sections for charm and light quarks at moderate and but diminishes rapidly at smaller or larger .
Using lattice QCD calculations in a charm-annihilation-forbidden approximation with varying light-quark masses, this study finds that near-threshold interactions are weak and provides no evidence for bound states or resonances in the energy region between the state and the threshold.
