Description
We have developed a hybrid hadronization model with two well-defined limits: string fragmentation for dilute systems, and quark recombination for dense sytems of partons. The model smoothly interpolates in between those limits by evaluating the probability of quark wave packets to coalesce with each other into hadronic wave functions as a deciding factor. We will discuss a new implementation in terms of a Monte Carlo hadronization code that can work with existing Monte Carlo event generators like PYTHIA and the JETSCAPE framework. Its main application is the hadronization of jets in a variety of different systems, with and without a thermal medium present. We will demonstrate the capabilities of our code by, e.g., studying the hadronization of full p+p events, including the underlying event, and by looking at jet and high momentum hadrons in A+A collisions. We will discuss how known medium effects, like an increased baryon/meson ratio, depend on the system size.
