Abstract

Jets are commonly used to study Quantum Chromodynamics and search for physics beyond the Standard model. Recent experimental results are analyzed to study hard and soft hadron production mechanisms within and out of the jets. The result of this work is the study of hadron production within and out of the jets produced in proton-proton collisions generated using Pythia 8.3 event generator. We report color reconnection effects on jet multiplicity, multiplicity for identified particles within the jets and transverse momenta distributions at 7 and 13 TeV.
