Parton Distribution Functions (PDFs) are essential non-perturbative inputs for calculation of any observable with hadronic initial states. These PDFs are released by individual groups as discrete grids as a function of the Bjorken-x and energy scale Q. The LHAPDF project at HepForge maintains a repository of PDFs from various groups in a new standardized LHAPDF6 format, as well as older formats such as the CTEQ PDS grid format. ManeParse is a package that provides PDFs within the Mathematica framework to facilitate calculating and plotting. The program is self-contained so there are no external links to any Fortran, C or C++ programs. The package includes the option to use the built-in Mathematica interpolation or a custom cubic Lagrange interpolation routine which allows for flexibility in the extrapolation (particularly at small x values). ManeParse is fast enough to enable simple calculations (involving even one or two integrations) to be easily computed in the Mathematica framework.

  1. Exclusive photoproduction of a di-meson pair with large invariant mass

    hep-ph 2026-05 unverdicted novelty 7.0

    Calculations of di-meson photoproduction amplitudes at leading order show cross sections up to 100 times larger than single-meson cases, enabling better GPD extraction.

  2. Probing Neutrino Compositeness with Invisible and Displaced Signals

    hep-ph 2026-04 unverdicted novelty 7.0

    Neutrinos disintegrate into dark jets in a composite sterile sector, producing enhanced neutral-to-charged current ratios and displaced vertices that probe compositeness scales at facilities like DUNE and FCC-ee.

    hep-ph 2026-07 conditional novelty 6.0

    A 146 GeV scalar explaining the CMS eμ excess prefers Y_eμ ~ 10^{-4.09} and is directly testable by Mu2e, COMET, Mu3e and related cLFV experiments.

    Computes the diffuse UHECR-boosted CνB flux across elastic, coherent, incoherent, resonance, and deep-inelastic channels with mixed-composition UHECR models and derives upper limits on CνB overdensity from IceCube and...

  5. Exclusive photoproduction of a di-meson pair with large invariant mass

    hep-ph 2026-05 unverdicted novelty 6.0

    Computes LO amplitudes for di-meson photoproduction channels sensitive to quark GPDs and reports high cross sections suitable for GPD studies at JLab energies.

  6. Electroweak Restoration: SMEFT and HEFT

    hep-ph 2026-05 unverdicted novelty 5.0

    High-energy amplitude ratios for longitudinal di-boson production approach unity in the SM and dimension-6 SMEFT but not necessarily in HEFT, making the W±_L Z_L to W±_L h cross section ratio a promising discriminator...
