Jet reconstruction techniques
W, Z and Higgs bosons decay predominantly into quarks which transform into sprays of particles called jets. In high energy proton-proton collisions at the LHC, the W/Z/H bosons can have such a large momentum that their decay products merge into a single particle jet. What is usually done to identify the decay products of the W/Z/H bosons as separate objects no longer works as they are merged in a single jet. It is therefore important to understand the substructure of these jets to identify the W/Z/H bosons by what is called W/Z/H-tagging. Throughout the run time of the LHC and the future collider HL-LHC, the transverse momenta reached will significantly increase, and at the same time the number of interactions (called pileup) happening in the same proton-proton bunch crossing will increase from order of 20 to 200. The focus of our group is to tackle these two challenges by developing new jet reconstruction techniques and by optimizing the relevant components of future detectors.
