چکیده

We have performed a detailed Monte Carlo exploration of the parameter space for a warped Higgsless model of electroweak symmetry breaking in 5 dimensions. This model is based on the SU(2)L×SU(2)R×U(1)B−L gauge group in an AdS5 bulk with arbitrary gauge kinetic terms on both the Planck and TeV branes. Constraints arising from precision electroweak measurements and collider data are found to be relatively easy to satisfy. We show, however, that the additional requirement of perturbative unitarity up to the cut-off, 10 TeV, in W L W− L elastic scattering in the absence of dangerous tachyons eliminates all models. If successful models of this class exist, they must be highly fine-tuned. ∗Work supported in part by the Department of Energy, Contract DE-AC03-76SF00515 †e-mails: [email protected], [email protected], and [email protected]

SLAC -PUB-233 October 1966 THE STANFORD TWO-MILE LINEAR ACCELERATOR*

In April 1957, Stanfc:rd University proposed the construction of a two-mile long linear electron accelerator capable of accelerating electrons to energies of 10 to 20 CeV for use in physics research. Congressional authorization for this machine was given in September 1961, and construction of the Stanford Linear Accelerator Center (SLAC) started in July 1962 on 480 acres of land near Stanford U...
