Prolegomena to a hybrid Classical/Rydberg simulator for hadronization (QuPYTH)

Kenneth Heitritter, PhD; University of Iowa

We present the classically simulated integration of a hadronization model, based on a two-leg ladder configuration of neutral Rydberg atoms, with the PYTHIA event generator. The real-time evolution of a single central excitation, interpreted as a charge-anticharge, on the two-leg ladder displays features similar to string-breaking reminiscent of the current Lund string fragmentation model used in PYTHIA for hadronization. We calculate the real-time evolution classically for a Rydberg simulator with up to 26 atoms. The behavior for increasing sites suggests that the model would be approaching semi-realistic hadron multiplicities using current QuEra hardware.phyiscs
