Probing strongly interacting electroweak dynamics through {ital W}{sup +}{ital W}{sup {minus}}/{ital ZZ} ratios at future {ital e}{sup +}{ital e}{sup {minus}} colliders
- Physics Department, University of Wisconsin, Madison, Wisconsin 53706 (United States)
We point out that the ratio of {ital W}{sup +}{ital W}{sup {minus}}{r_arrow}{ital W}{sup +}{ital W}{sup {minus}} and {ital W}{sup +}{ital W}{sup {minus}}{r_arrow}{ital ZZ} cross sections is a sensitive probe of the dynamics of electroweak symmetry breaking, in the c.m. energy region {radical}{ital s}{sub {ital W}{ital W}} {approx_gt}1 TeV where vector boson scattering may well become strong. We suggest ways in which this ratio can be extracted at a 1.5 TeV {ital e}{sup +}{ital e}{sup {minus}} linear collider, using {ital W}{sup {plus_minus}},{ital Z}{r_arrow}{ital jj} hadronic decays and relying on dijet mass resolution to provid statistical discrimination between {ital W}{sup {plus_minus}} and {ital Z}. {ital WW} fusion processes studied here are unique for exploring scalar resonances of mass of about 1 TeV and are complementary to studies via the direct channel {ital e}{sup +}{ital e}{sup {minus}}{r_arrow}{ital W}{sup +}{ital W}{sup {minus}} for the vector and nonresonant cases. With an integrated luminosity of 200 fb{sup {minus}1}, the signals obtained are statistically significant. A comparision with a study of the {ital e}{sup {minus}}{ital e}{sup {minus}}{r_arrow}{nu}{nu}{ital W}{sup {minus}}{ital W}{sup {minus}} process is made. Enhancements of the signal rate from using a polarized electron beam, or at a 2 TeV {ital e}{sup +}{ital e}{sup {minus}} linear colider and possible higher energy {mu}{sup +}{mu}{sup {minus}} colliders, are also presented.
