چکیده
We analyze the potential of the CERN Large Hadron Collider (LHC) to search for excited spin-12 electrons and neutrinos. Assuming a SU(2)L⊗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±νV with V = γ, 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.

Large Hadron Collider (LHC) at CERN will provide excellent opportunity to study the production and decay of heavy mesons and baryons with high statistics. We aim at the heavy mesons in this work and calculate their fragmentation functions consistent with this machine and present their total fragmentation probabilities and average fragmentation parameters.
متن کاملHiggs Decays into Leptons *
We discuss the prospects for the discovery of neutral Higgs bosons (φ 0 = H 0 , h 0 , A 0) in multi-Higgs doublet models via their decays into leptons at hadron colliders. A major focus will be searching for Higgs bosons produced with bottom quarks via Higgs decays into muon pairs (pp → b ¯ bφ 0 → b ¯ bµ¯ µ + X) at the CERN Large Hadron Collider within the framework of the minimal supersymmetri...
متن کاملProduction of Excited Neutrino at LHC
The proliferation of quarks and leptons can be naturally explained by the assumption that they are composite objects. According to models of compositeness[1], known fermions are bound states of more fundamental constituents – preons [2] or a fermion and a boson [3]. In the framework of these models, constituents of known fermions interact by means of new strong gauge interactions. One of the ma...
متن کاملPair production of the T-odd leptons at the LHC
The T-odd leptons predicted by the littlest Higgs model with T-parity can be pair produced via the subprocesses gg → l+Hl − H , qq → l + Hl − H , γγ → l + Hl − H and V V → l+Hl−H (V=W or Z) at the CERN Large Hadron Collider (LHC). We estimate the hadronic production cross sections for all of these processes and give a simply phenomenology analysis. We find that the cross sections for most of th...
متن کاملObserving Strongly Interacting Vector Boson Systems at the CERN Large Hadron Collider
We explore the potential of the CERN Large Hadron Collider to access a strongly interacting electroweak symmetry breaking sector via weak boson scattering with W+W−jj, ZZjj and WZjj final states. As examples of models with scalar or vector resonances we concentrate on a scenario with a heavy Higgs boson and on a Warped Higgsless Kaluza-Klein model of narrow spin-one resonances. The signal and t...
