Photon and Z induced heavy charged lepton pair production at a hadron supercollider

We investigate the pair production of charged heavy leptons via photon-induced processes at the proposed CERN Large Hadron Collider (LHC). Using effective photon and Z approximations, rates are given for $L^+L^-$ production due to $γγ$ fusion and $Z γ$ fusion for the cases of inelastic, elastic and semi-elastic $pp$ collisions. These are compared with the corresponding rates for production via the gluon fusion and Drell-Yan mechanisms. Various $γγ$ and $Z γ$ differential luminosities for $pp$ collisions are also presented.

Heavy Charged Lepton Pair Production Through Photon Fusion at Hadron Supercolliders

The pair production of charged heavy leptons via two photon fusion is considered for hadron collisions at SSC and LHC energies. Rates for the inelastic process $pp \rightarrow γγX \rightarrow L^+L^-X$ and the elastic process $pp \rightarrow γγpp \rightarrow L^+L^- pp$ are given in a Weizsäcker-Williams approximation and compared with production via the gluon fusion and Drell-Yan mechanisms

Constraints on Anomalous $WWγ$ Couplings From $eγ$\ Collisions

We study the potential for using $eγ$\ collisions produced by backscattered laser photons to investigate WW$γ$\ couplings. We present results for Next Linear Collider energies of 500 GeV and 1 TeV. We find that where statistics allow, off W mass shell results can be quite important, complementing on W mass shell results from this and other studies. It is shown that $eγ$\ colliders would prove quite valuable in the investigations of W-boson physics.

Production of the Lightest Supersymmetric Particle in Electron-Photon Collisions

We present cross sections for the production of the lightest supersymmetric particle as a neutralino state in the minimal supersymmetric standard model at electron-photon colliders. The lightest supersymmetric particle mass is taken at a value of 30 GeV which is slightly higher than its lowest experimental bound of 20 GeV, and the masses of the scalar electron are varied. We show partial cross sections of the energy and angular distribution of the outgoing electron for different values of the centre of mass energy. As a result we show that electron-photon collider experiments could be quite sensitive to the detection of supersymmetric particles.
