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 extends the semileptonic sum rule to include strange baryon and meson decays, quantifies the impact of SU(3) symmetry breaking to confirm it remains within experimental uncertainties, and proposes new predictive sum rules to rigorously test the consistency of processes.
This paper responds to a comment by Huang and Li by acknowledging an overlooked real-value condition in their previous work on reflection symmetry while clarifying that Inverted Ordering remains in tension with current experimental bounds on the sum of neutrino masses, despite being permitted by effective neutrino mass constraints.
This paper demonstrates that the injection of both dark and electromagnetic radiation between Big Bang nucleosynthesis and recombination is tightly constrained by the dilution of the baryon-to-entropy ratio, limiting the total allowed extra radiation to approximately 25% more than if it were purely dark radiation.
This study demonstrates that in high-energy oxygen-oxygen collisions at 5.36 TeV, the produced QCD matter only partially reaches local equilibrium, necessitating a core-corona framework rather than a purely hydrodynamic approach to accurately describe the dynamics, particularly the incomplete chemical equilibrium observed in strange baryon yields.
This paper demonstrates that non-standard early Universe expansion histories, specifically faster-than-radiation expansion and scalar-tensor gravity, can enable successful Type-III leptogenesis with triplet fermion masses in the TeV to few-hundred-TeV range, significantly lowering the energy scale compared to the standard radiation-dominated scenario.
This paper explores a framework for gauge coupling unification using non-renormalizable operators in , demonstrating that while fermion condensates in the 5 representation fail due to proton decay constraints, viable models achieving both unification and doublet-triplet splitting can be constructed using condensates in the 10 and 24 representations.
This study demonstrates that using transverse spherocity to classify Pb+Pb collisions into isotropic and jetty topologies provides a cleaner and more reliable method for probing the Chiral Magnetic Effect by effectively suppressing flow-driven and resonance-decay backgrounds compared to traditional flow-vector-based approaches.
This paper investigates pion valence quark parton distribution functions using a light-cone quark model, demonstrating that the evolved distributions and predicted structure functions align well with experimental data from DESY-HERA and theoretical extractions while also providing predictions for future electron-ion collider kinematics.
This paper demonstrates that superpositions of toroidal electromagnetic pulses propagating in free space naturally generate localized regions where , thereby producing a co-propagating, space-time localized pseudoscalar field within the framework of axion electrodynamics, distinct from the physical creation of axion particles.
By jointly analyzing DESI DR2, Pantheon+, and Cosmic Chronometers data, this study finds that dynamical dark energy models with a time-varying equation of state provide a better fit and are favored over the standard CDM model, though current constraints remain moderate and future high-precision observations are needed for definitive conclusions.
