Description
We present the first results from the JETSCAPE multi-stage event generator framework for electron-ion collisions. The use of calibrated modules from the JETSCAPE framework allows common model parameters to remain unchanged between p-A and e-A simulations, thereby introducing novel constraints on these extensive simulations. The e-A event generator within the JETSCAPE framework simulates an incoming virtual photon scattering off a quark, which develops into a parton shower within the extended nucleus described by the 3D-Glauber model [1]. The interacting shower is simulated using the multi-stage, recoil-based formalism of MATTER+LBT, similar to that carried out for A-A and p-A in JETSCAPE [2,3,4]. The distributions of incoming partons are sampled using a Transverse Momentum Dependent Parton Distribution Function (TMDPDF) within each nucleon. Keeping track of the color structure of the shower and recoil partons, as well as the wounded nucleons, allows for the incorporation of extensive string-based hadronization routines inside a nuclear environment. We present preliminary results on the attenuation, dihadron correlation, and transverse broadening of leading hadrons produced in Deep Inelastic Scattering on Neon, Krypton, and Xenon, and compare these with data from the HERMES collaboration.
