Jets are collimated bunches of hadrons, originating from quarks and gluons. They are produced in high energy proton-proton collisions at the Large Hadron Collider (LHC). It has direct manifestations to study different aspects of QCD and thus provide useful inputs to improve Monte Carlo model predictions in order to achieve precise measurements for Standard Model processes. LHC is a jet factory and thus either jets are the most dominating background in almost all new particle searches or it itself can act as a proxy of a new particle decaying hadronically. The higher is the energy of the LHC the more collimated is the hadronic decay products, resulting in the formation of a large radius jet. The internal structure of this jet is pretty much different from the structure of a QCD jet. Therefore this property is extensively utilized for signal background discrimination for a new particle search. Jet study is a wide ranging, a very rapidly developing eld in LHC, widening the scope of its discovery potential at every new energy regime LHC runs. In this presentation I will talk about some distinct features of jets, some recent jet measurements and jet related searches.
