STRONGLY-INTERACTING ELECTROWEAK SECTOR AT e-e- COLLIDERS

STRONGLY-INTERACTING ELECTROWEAK SECTOR AT e − e − COLLIDERS ∗

It has been pointed out that a TeV e−e− linear collider may be unique in probing new physics in the weak isospin I = 2 channel for the longitudinalWW scattering1,2 W− L W − L → W− L W− L . Even if there is no resonance in this channel, a stronglyinteracting electroweak sector (SEWS) may still yield a sufficiently large signal rate. However, the continuum standard model (SM) backgrounds are subs...

Tests for a Strong Electroweak Sector at Future e+e− High Energy Colliders

The study of the scattering at high energy of the gauge bosons W and Z, in particular longitudinally polarized W and Z, can clarify the mechanism of spontaneous symmetry breaking in the Standard Model of the electroweak interactions. Different models of strong electroweak sector, based on the effective lagrangian approach are briefly reviewed. They include models with no resonance, with scalar ...

Production cross section estimates for strongly-interacting Electroweak Symmetry Breaking Sector resonances at particle colliders

We are exploring a generic strongly-interacting Electroweak Symmetry Breaking Sector (EWSBS) with the low-energy effectie field theory for the four experimentally known particles (W L , ZL, h) and its dispersion-relation based unitary extension. In this contribution we provide simple estimates for the production cross section of pairs of the EWSBS bosons and their resonances at proton-proton co...

PRECISION TESTS OF THE ELECTROWEAK INTERACTIONS AT e + e − COLLIDERS

This paper is an updated version of the lectures given at the XXIX International Meeting on Fundamental Physics in Sitges, Barcelona (February 2001). The measurements performed at LEP and SLC have substantially improved the precision of the test of the Minimal Standard Model. The precision is such that there is sensitivity to pure weak radiative corrections. This allows to indirectly determine ...
