EXCITED FERMIONS


An introduction to excited fermions and an overview of our studies and main recent results on excited fermions is also given in the talk at the H1 Crosstalk'00.


If leptons and quarks are not elementary particles but are composite, excited states of these particles can exist, called excited fermions. HERA, having electron and proton in the initial state, is a good place to search for them. They are sought via the decay into an ordinary fermion and a gauge boson, e.g. e* -> e gamma.
