Abstract: We present our results for a flavor-dependent European Muon Collaboration (EMC) effect based on the nIMParton nuclear parton distribution functions, in which the x dependence is described with a nucleon swelling model. The nuclear correction from nucleon swelling is considered through a modification of the initial valence quark distributions instead of a dynamical rescaling. To probe the flavor dependence of the model, the experimental observables are calculated by applying nIMParton nuclear modifications for various experiments: parity-violating deep inelastic scattering on nuclear target, pion-induced Drell-Yan, and W-boson production in proton-nucleus collisions. In addition, we present the expected effect for the spectator-tagged deep inelastic scattering process, which will be performed by the CLAS12 collaboration with the ALERT (shorted for A Low Energy Recoil Tracker) detector.
