摘要：

We analyze the potential of the CERN Large Hadron Collider (LHC) to search for excited spin-<fraction shape=1/2 electrons and neutrinos. Assuming an SU(2)(L)circle times U(1)(Y) invariant model, we study in detail the single production of excited electrons and neutrinos and respective backgrounds through the reactions pp -> e(+)e(-)V and e(+/-)nu V with V=gamma, W, or Z. We show that the LHC will be able to tighten considerably the direct constraints on these possible new states, probing excited lepton masses up to 1-2 TeV depending on their couplings to fermions and gauge bosons.
