Description
At high energy particle colliders like the LHC collimated sprays of particles are frequently produced which are known as jets. Measurements involving jets and their substructure are used as precision probes of the standard model, to study the Quark Gluon Plasma in heavy-ion collisions and for searches of physics beyond the standard model. In the complicated environment at the LHC, jet grooming algorithms are used to reduce the size of nonperturbative corrections. The most frequently technique is the so-called soft drop algorithm. In this talk, I will present first principles calculations in perturbative QCD of different jet substructure observables measured on jets after applying the soft drop algorithm including the jet mass, the jet radius and the momentum sharing fraction.
