    Impact of SeaQuest data on PDF fits at large x by S. Alekhin, M. V. Garzelli, S. Kulagin, S.-O. Moch

    Published 2023-09-01
    “…We find these data in a good agreement with the QCD predictions based on PDFs fitted to the Tevatron and LHC data on forward production of W and Z bosons. As a basis for this study we use the ABMP16 PDF fits and show that they turn out to be compatible with the SeaQuest data, and that these data have constraining power, allowing to reduce the uncertainties on the isospin asymmetry of the light-sea-quark distribution at large longitudinal momentum fraction x. …”

    Flavor Physics in the Randall-Sundrum Model: I. Theoretical Setup and Electroweak Precision Tests by Casagrande, S, Goertz, F, Haisch, U, Neubert, M, Pfoh, T

    Published 2008
    “…Detailed studies of the flavor-changing couplings of the Higgs boson and of gauge bosons and their KK excitations are performed, including in particular the couplings of the standard W and Z bosons. A careful analysis of electroweak precision observables including the S and T parameters and the Zbb couplings shows that the simplest RS model containing only Standard Model particles and their KK excitations is consistent with all experimental bounds for a KK scale as low as a few TeV, if one allows for a heavy Higgs boson and/or for an ultra-violet cutoff below the Planck scale. …”

    Potential for Definitive Discovery of a 70GeV Dark Matter WIMP with Only Second-Order Gauge Couplings by Roland Allen, Bailey Tallman, Alexandra Boone, Adhithya Vijayakumar, Fiona Lopez, Samuel Apata, Jehu Martinez

    Published 2023-02-01
    “…Using our calculations and estimates of these cross-sections, we discuss the potential for discovery of a recently proposed dark matter WIMP which has a mass of about 70 GeV/c$^2$ and only second-order couplings to W and Z bosons. There is evidence that indirect detection may already have been achieved, since analyses of the gamma rays detected by Fermi-LAT and the antiprotons observed by AMS-02 are consistent with 70 GeV dark matter having our calculated $\langle \sigma_{ann} v \rangle \approx 1.2 \times 10^{-26} $ cm$^3$/s. …”
