Elementary Particle Physics Seminar

Wednesday, October 28th 2015
Speaker: Debarati Roy, Saha Institute of Nuclear Physics, Kolkata, India
Subject: Reconstructing Events with Jets at the LHC

Jets are very important tool in studying physics at a hadron collider like the LHC. They are the direct manifestations of quarks and gluons and they constitute the most essential tool to test QCD. In this seminar I will talk about the reconstruction of jets in the LHC. It involves combining the information from several detectors. It also includes the best possible calibration of the detector elements, jet energy correction from information of collision data as well as Monte Carlo, correcting from the effect of pile up events etc. Reconstructed jets are then utilized in computing several variables used in understanding perturbative as well as non-perturbative QCD effects, and also as efficient tools in search of new physics. Some of the tests of the Standard Model will be discussed.
