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 proposes that parton-level differential polarization fractions serve as optimal observables for maximizing sensitivity in vector-boson polarization measurements, a method demonstrated in inclusive ZZ production that can be learned by neural networks to combine model-independent fiducial cross-section analysis with the best achievable sensitivity for detecting new physics.
This paper demonstrates that using flattenicity as an event classifier in proton-proton collisions at 13 TeV significantly reduces selection biases inherent in multiplicity-based estimators, thereby providing a more reliable tool for investigating potential jet quenching effects and quark-gluon plasma formation in small systems.
This paper presents a full general relativity study of two-fluid -mode oscillations in neutron stars admixed with self-interacting bosonic dark matter, revealing that while dark matter cores significantly reduce gravitational-wave damping times in a mass-fraction-dependent manner, dark matter halos increase them, thereby offering a distinct spectral signature to distinguish dark matter admixtures from soft nuclear equations of state.
This paper demonstrates that retaining the complete one-loop square () in next-to-leading-order calculations for exclusive production in ultraperipheral collisions resolves unphysical negative cross-sections at high transverse momentum, increases integrated rates by 11.6%–18.4%, and significantly reduces scale uncertainties compared to the conventional approach.
This paper demonstrates that angular observables in the rare decay of polarized baryons to provide unique access to orthogonal Wilson coefficient combinations and CP-violating phases, thereby resolving parameter degeneracies and enabling a complete characterization of new physics in transitions that is inaccessible in mesonic decays.
This paper reviews the current status and future prospects of precision weak neutral current measurements in fixed-target scattering, atomic parity violation, and low-momentum-transfer collider experiments, with a specific focus on upcoming parity-violating electron scattering initiatives at Jefferson Laboratory and Mainz.
This paper resolves the issue of negative decay and production rates in perturbative Quantum Chromodynamics by proposing that for exclusive processes, probability should be defined as the modulus square of the truncated amplitude rather than its truncated square, a prescription that restores positivity and improves convergence in NNLO calculations.
This paper demonstrates that Supersymmetric Grand Unified Theories with gauge mediation can be probed through proton decay measurements at the Hyper-Kamiokande experiment for lower GUT scales and via searches for heavy gluinos and squarks at future 100 TeV proton-proton colliders for higher GUT scales, thereby offering insights into the messenger scale and supersymmetry breaking mechanisms.
This paper presents a machine-learning-based framework for identifying highly boosted, leptonically decaying top quarks at the 100 TeV FCC-hh, demonstrating that both variable-based and constituent-based taggers achieve comparable performance and enabling a search for vector-like quarks with a discovery reach of up to 10 TeV.
This paper utilizes low-energy solar neutrino-electron scattering data from the PandaX-4T and XENONnT experiments to establish novel, improved exclusion limits on six anomaly-free dark photon models and their mixing parameters, particularly in the sub-MeV mediator mass regime.
