Abstract
Jet quenching is a significant phenomenon for studying the properties of the Quark-Gluon Plasma (QGP), typically observed in heavy-ion collisions. This phenomenon refers to the substantial energy loss experienced by high-energy jets as they traverse the QGP. This study explores whether a similar effect occurs in proton-proton (pp) collisions. We simulated 10,000 proton-proton collision events using the PYTHIA event generator, with a center-of-mass energy set to 5360 GeV and a minimum transverse momentum threshold (pthatmin) of 500 GeV. Neutrino events were excluded from the simulation to focus on high-energy jets. The jet reconstruction was carried out using FastJet software and the inverse kT algorithm (R = 0.4), followed by fitting the four-momentum of the reconstructed jet using the ATLAS jet energy resolution curve, which helps to approximate the actual detector response more accurately. This study focuses on the correlation between the missing transverse momentum (MET) and the secondary jet volume ratio (pT2/pT1). It is found that the MET value falls below 40 GeV when pT2/pT1 is smaller than 0.4 and, due to the coverage of the detector, when the contribution of W bosons or neutrinos is extremely small. In addition, we study the distributions of the leading and secondary jets in terms of pseudo-combination (η) and polar angle (θ) in this case.
