Title: Deconstruction and elastic {pi}{pi} scattering in Higgsless models

Abstract

We study elastic pion-pion scattering in global linear moose models and apply the results to a variety of Higgsless models in flat and anti-de Sitter (AdS) space using the equivalence theorem. In order to connect the global moose to Higgsless models, we first introduce a block-spin transformation which corresponds, in the continuum, to the freedom to perform coordinate transformations in the Higgsless model. We show that it is possible to make an 'f-flat' deconstruction in which all of the f-constants f{sub j} of the linear moose model are identical; the phenomenologically relevant f-flat models are those in which the coupling constants of the groups at either end of the moose are small--corresponding to the global linear moose. In studying pion-pion scattering, we derive various sum rules, including one analogous to the Kawarabayashi-Suzuki-Riazuddin-Fayyazuddin (KSRF) relation, and use them in evaluating the low-energy and high-energy forms of the leading elastic partial-wave scattering amplitudes. We obtain elastic unitarity bounds as a function of the mass of the lightest KK mode and discuss their physical significance.

  • We analyze inelastic 2{yields}2 scattering amplitudes for gauge bosons and Nambu-Goldstone bosons in deconstructed Higgsless models. Using the (KK) equivalence theorem in 4D (5D), we derive a set of general sum rules among the boson masses and multiboson couplings that are valid for arbitrary deconstructed models. Taking the continuum limit, our results naturally include the 5D Higgsless model sum rules for arbitrary 5D geometry and boundary conditions; they also reduce to the elastic sum rules when applied to the special case of elastic scattering. For the case of linear deconstructed Higgsless models, we demonstrate that the sum rules can alsomore » be derived from a set of general deconstruction identities and completeness relations. We apply these sum rules to the deconstructed 3-site Higgsless model and its extensions; we show that in 5D ignoring all higher KK modes (n>1) is inconsistent once the inelastic channels become important. Finally, we discuss how our results generalize beyond the case of linear Higgsless models.« less
  • This talk reviews recent progress in Higgsless models of electroweak symmetry breaking, and summarizes relevant points of model-building and phenomenology.
  • The three-site model has been offered as a benchmark for studying the collider phenomenology of Higgsless models. In this paper we analyze how well the three-site model performs as a general exemplar of Higgsless models in describing W{sub L}W{sub L} scattering, and which modifications can make it more representative. We employ general sum rules relating the masses and couplings of the Kaluza-Klein modes of the gauge fields in continuum and deconstructed Higgsless models as a way to compare the different theories. We show that the size of the four-point vertex for the (unphysical) Nambu-Goldstone modes and the degree to whichmore » the sum rules are saturated by contributions from the lowest-lying Kaluza-Klein resonances both provide good measures of the extent to which a highly deconstructed theory can accurately describe the low-energy physics of a continuum 5D Higgsless model. After comparing the three-site model to flat and warped continuum models, we analyze extensions of the three-site model to a longer open linear moose with an additional U(1) group and to a ring ('breaking electroweak symmetry strongly' or 'hidden local symmetry') model with three sites and three links. Both cases may be readily analyzed in the framework of the general sum rules. We demonstrate that W{sub L}W{sub L} scattering in the ring model can very closely approximate scattering in the continuum models, provided that the hidden local symmetry parameter a is chosen to mimic {rho}-meson dominance of {pi}{pi} scattering in QCD. The hadron and lepton collider phenomenology of both extended models is briefly discussed, with a focus on the complementary information to be gained from precision measurements of the Z{sup '} line shape and ZWW coupling at a high-energy lepton collider.« less
  • Within a unitary ..pi..NN theory a set of coupled integral equations defined in the NNdirect-sumN..delta.. direct-sum..pi..NN subspace has been derived for examining the extent to which the NN and ..pi..d elastic scattering data can be both described by a class of meson-exchange ..pi..NN models. The considered models are constructued by using a previously developed subtraction procedure to extend the Paris, Bonn, Argonne-V14, and Reid NN potentials to include the coupling to the ..pi..NN production channel. The pion production through the ..delta.. excitation is described by a ..pi..Nbold-arrow-left-right..delta.. vertex and a V/sub NN//sub bold-arrow-left-right//sub N//sub ..delta../ transition potential, while the productionmore » through nonresonant ..pi..N interactions is described by a transition operator F/sub ..pi..//sub NN//sub bold-arrow-left-right//sub NN/. It is found that none of the constructed models can accurately reproduce all NN and ..pi..d elastic scattering data, in particularly the data of polarization observables. Our results indicate that either the conventional phenomenological parametrizations of baryon-baryon interaction at short distances are not valid in the intermediate energy region, or some genuine quark dynamics has already been revealed in the ..pi..NN data.« less
