Estudio del canal electronico de desintegracion del lepton tau en LEP con el detector DELPHI

Jose Julio Lozano Bahilo

This thesis presents a study of the decays $\tau \to e\nu \overline{\nu }$ identified after a selection of ${\tau }^{+}{\tau }^{-}$ events produced in $e^{+}{e}^{-}$ collisions at LEP. These collisions, pre…
