A MODEL OF LOW-LYING STATES IN STRONGLY INTERACTING ELECTROWEAK SYMMETRY-BREAKING SECTOR

It is proposed that, in a strongly-interacting electroweak sector, bes ides the Goldstone bosons, the coexistence of a scalar state (H) and v ector resonances such as A(1) [I-G(J(P)) = 1-(1(+))], V [1+(1(-))] and omega(H) [0(-)(1(-))] is required by the proper Regge behavior of the forward scattering amplitudes. This is a consequence of the following well-motivated assumptions: (a) Adler-Weisberger-type sum rules and t he superconvergence relations for scattering amplitudes hold in this s trongly interacting sector; (b) the sum rules at t = 0 are saturated b y a minimal set of low-lying states with appropriate quantum numbers. It therefore suggests that a complete description should include all t hese resonances. These states may lead to distinctive experimental sig natures at future colliders.
