  • Modified PYTHIA mPDFs better satisfy symmetry and sum rules

    What the study found A modified algorithm based on PYTHIA produces equal-scale multi-parton distribution functions that are symmetric and satisfy the relevant sum rules more closely than earlier PYTHIA-based results. Why the authors say this matters The authors state that multi-parton distribution functions are important for predicting multiple scattering rates at hadron colliders, and the…

  • Transformer identifies heavily modified jets in heavy-ion collisions

    What the study found The study found that a Transformer classifier can identify a class of jets in nucleus-nucleus collisions that have been unequivocally modified. It also found a robust estimate of the upper bound for the fraction of jets in nucleus-nucleus collisions that are indistinguishable from those produced in proton-proton collisions. Why the authors…
