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 presents a modified PYTHIA 8.3 model incorporating string closepacking, popcorn destructive interference, and strange junctions to successfully describe the LHC-observed enhancement of strange hadron production in high-multiplicity pp collisions, offering a competitive alternative to existing tunes while addressing specific challenges in baryon ratios and transverse momentum spectra.
This paper proposes a cosmological uncertainty relation based on a deformed commutation for the scale factor that introduces a geometric correction to the Friedmann equation, offering a unified framework where a single parameter can explain both late-time cosmic acceleration and a non-singular Big Bang bounce without requiring new particles or fields.
This paper proposes a novel "stochastic axion mixing" mechanism in multi-axion frameworks that naturally occurs when ultra-light axion-like particles have distinct masses below the QCD axion mass, offering a generalized formalism independent of decay constant hierarchies that encompasses the conventional maximal mixing scenario as a specific subset.
This paper utilizes kinetic theory within the relaxation time approximation to investigate charge transport in a relativistic drifting plasma, deriving Hall and polarization drift currents under constant and time-dependent electromagnetic fields and providing quantitative estimates of these effects in quark-gluon plasma.
This paper summarizes a presentation on the moduli-dependent Species Scale in Quantum Gravity, demonstrating how it governs the differential equations of one-loop Wilson coefficients for BPS operators and generates a one-loop potential that stabilizes Kähler moduli at "desert points" in Type IIB orientifolds.
This paper constructs and analyzes semileptonic sum rules for transitions involving orbitally excited charm hadrons, finding that while deviations from the small-velocity limit and tensor contributions are significant, robust predictions for lepton-universality ratios currently require better-constrained hadronic form factors.
This paper outlines the DAMSA experiment, a novel short-baseline accelerator/beam dump proposal designed to probe MeV-to-sub-GeV dark-sector messengers and rare Standard Model signals by overcoming traditional sensitivity limits through an ultra-short baseline and a compact, background-mitigated detector, with its feasibility to be validated by the proposed DAMSA Path-Finder proof-of-concept experiment at SLAC.
This paper introduces a framework utilizing linear response and influence functions to quantify how experimental data constrains non-perturbative functions in global QCD analyses, thereby providing a transparent method to diagnose information flow and sensitivity in these complex inverse problems.
This paper presents the first calculation of next-to-next-to-leading order (NNLO) QCD radiative corrections for deeply virtual pion production, demonstrating that these two-loop corrections substantially improve the agreement between perturbative QCD predictions and experimental data from JLab while also refining theoretical descriptions of transverse single-spin asymmetries for future facilities like the EIC and EicC.
This paper demonstrates that the zero-mass limit of the partition function for covariant locally localized gravity on a Karch-Randall braneworld yields a theory containing a massless graviton and a decoupled massive vector, rather than the standard Randall-Sundrum II model, by deriving a fully covariant description to compute the one-loop partition function.
