Effect of color reconnection and rope formation on resonance production in p–p collisions in Pythia 8

Abstract Resonance production in proton–proton collisions at $$\sqrt{s} = 7$$ s = 7 TeV and 13 TeV have been investigated using a Pythia 8 event generator within the framework of microscopic processes including color reconnection and rope hadronization. Specifically, the observable effects of differ...
