    Signals of strong parity violation in deep inelastic scattering

    Alessandro Bacchetta🇮🇹 · Matteo Cerutti🇮🇹 · Ludovico Manna🇮🇹 · Marco Radici🇮🇹 · Xiaochao Zheng🇺🇸

    We include strong parity-violating contributions to inclusive deep inelastic scattering (DIS) of longitudinally polarized leptons off an unpolarized target. At variance with standard results, we obtain nonvanishing parity-violating structure functions in the case of pure photon exchange. The addition of these strong parity-violating contributions improves the description of existing experimental data on DIS parity-violating asymmetries. We find the size of these contributions small but exhibiting a deviation from zero of about 1.5 . The associated -value is 0.063, indicating that the probability of making an error by rejecting the hypothesis of no parity-violating contributions is 6.3\%, which is small but not negligible. Further improvement on the limit of the strong parity-violation can be expected from the future SoLID program at Jefferson Lab.

    The 3+1D initialization and evolution of the Glasma

    Scott McDonald🇨🇦 · Sangyong Jeon🇨🇦 · Charles Gale🇨🇦

    The IP-Glasma initial condition has been highly successful in the phenomenology of ultra-relativistic heavy ion collisions. The assumption of boost invariance, however, while good for collision energies probed at the LHC, limits the use of IP-Glasma to the transverse dynamics of heavy ion collision to near mid-rapidity. There is a wealth of physics to be explored and understood in the longitudinal dynamics of heavy ion collisions, and a full understanding of heavy ion collisions can only come from 3-dimensional studies. In particular, long range rapidity correlations are seeded in the initial collision and provide additional information on the high energy nuclear wave functions that has thus far been inaccessible to the IP-Glasma model. In this work, we introduce a way to extend the IP-Glasma model to 3+1-dimensions while preserving its key features.
