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 provides a proof, valid to all orders in perturbation theory, that the six fixed points of the massless 1-loop renormalization group running of the CKM matrix in the Standard Model remain fixed points without requiring the extra assumptions present in previous work.
This study quantitatively evaluates various theoretical frameworks against data across the full NA61/SHINE system-size ladder, revealing that no single model explains the entire dataset but that a combination of core-corona and canonical statistical models successfully describes the observed step-like enhancement of strangeness production and the "horn" structure in heavy-ion collisions.
By analyzing the low-energy expansion of a 1PI effective action, this paper demonstrates that within QCD itself, it is impossible to simultaneously resolve both the and strong- problems with light quarks and a small angle, as avoiding violation at small non-zero would require the anomaly-induced contribution to the pseudoscalar mass matrix to be negligible, effectively implying the problem remains unsolved.
By analyzing production at RHIC energies through transport equations, this study demonstrates that continuous suppression via thermal decay, rather than sudden color screening, is the dominant mechanism responsible for quarkonium suppression in heavy-ion collisions.
This paper investigates the discovery potential of singly produced vector-like top quarks () decaying via at future muon-proton colliders, demonstrating through full detector simulations that this channel offers complementary sensitivity and unique advantages for probing high-mass VLQs compared to other decay modes and collider facilities.
This paper explicitly proves previously proposed K-identities for n-point hard string scattering amplitudes and introduces a generating function for an infinite set of generalized K-identities, where the lowest and next-to-leading orders correspond to the scattering equations in the CHY formalism and the original K-identities, respectively, suggesting their utility for calculating higher-order amplitudes.
This study extends the FastReso framework to incorporate thermal broadening of light vector-meson spectral functions, revealing that while finite-width effects increase low-momentum pion yields and partially reduce discrepancies between models and LHC data, they do not fully resolve the soft pion puzzle in heavy-ion collisions.
This paper investigates how including next-to-leading-order QCD and electroweak corrections to dimension-6 SMEFT predictions for Higgs decays impacts the precision of Higgs coupling constraints at the HL-LHC, revealing that these higher-order effects are most significant for third-generation fermion operators and the Higgs trilinear coupling.
This paper revisits the magnitude of Pomeron loop corrections to single Pomeron exchange by numerically evaluating the expression using Korchemsky's triple Pomeron vertex representation, finding that while the loops do not exceed the single Pomeron contribution as previously claimed, they still provide a significant 24%–39% correction at the lowest accessible values and hard scales near the non-perturbative boundary.
This paper models and constrains indirect dark matter detection signatures arising from dark photon trident decays in celestial objects, demonstrating that gamma-ray observations can provide stronger limits on dark matter-baryon scattering cross-sections than current direct detection methods and potentially penetrate the neutrino fog.
