Description
The Standard Model of particle physics is an incomplete theory and it seems to be an approximation of a deeper and more fundamental theory. The idea that might lead to a better understanding of the universe is that the quarks and leptons, which are now treated as point-like particles are composite in nature having underlying substructure and made up of even smaller particles bound together with some force. This force must be very strong. The underlying substructure implies the existence of stable excited states, which will have higher energy and can decay into lower-energy states. The existence of excited states is a natural consequence of composite models for quarks and leptons. Compositeness models predict the existence of excited states of quarks and leptons at this characteristic scale of the new binding interaction. Considerable efforts have been expended into the search of excited leptons by various collaborations including at the LHC and limits have been set on the masses and coupling of excited leptons.
Keywords: Standard Model, leptons, quarks, excited, Compositeness, LHC.
