Hello I am new into jetphysics and I read here that 'Hadronic jets are amongst the most striking phenomena in high-energy physics'.
My small understanding of jets is that they are defined by the hadrons that are composed from the decay process. (Jets are shapes starting from a collision point up and the energy/radiation shower of hadrons that we can observer in the detector calorimeters).
I want to know if there are non-hadronic jets, and if so how are they defined. Or if something fundamental I miss. Any introducttonary textbook suggestions on the subject is very welcome. Thank you in advance
