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 ...

The large rapidity interval available at the Large Hadron Collider (LHC) offers an arena in which the QCD aspects of diffraction may be explored in an environment free of gap survival complications using events with multiple rapidity gaps. Presented at DIS-2005, XIIIth International Workshop on Deep Inelastic Scallering, April 27 May 1 2005, Madison, WI, U.S.A.

Results are presented on the discovery potential for MSSM neutral Higgs bosons in the mh −max scenario. The region of large tanβ, between 15 and 50, and mass between ≈ 95 and 130 GeV is considered in the framework of the ATLAS experiment at the Large Hadron Collider (LHC), for a centre-of-mass energy √ s = 14 TeV. This parameter region is not fully covered by the present data either from LEP or...

We point out that interesting signals of the non-strongly interacting sector of the supersymmetric standard model arise from the production of charginos and neutralinos via vector boson fusion (VBF) at the Large Hadron Collider (LHC). In particular, if R-parity is violated, the hadronically quiet signals of charginos and neutralinos through direct production get considerably suppressed. We show...

The discovery of the Standard Model (SM) or supersymmetric (SUSY) Higgs bosons belongs to the main endeavors of the Large Hadron Collider (LHC). In this article the status of the signal and background calculations for Higgs boson production at the LHC is reviewed.
