We compute their contribution to the electroweak gauge bosons decay width and to the single-photon and single-Z processes. With CERN LEP-I results and assuming nonobservation at LEP-II we present exclusion plots for the brane tension tau=f(4) and the branon mass M. Prospects for the next generation of electron-positron colliders are also considered.engjournal articlehttp://prd.aps.org/abstract/PRD/v67/i7/e075010http://www.aps.orgopen access53Goldstone BosonsExtra DimensionsMillimeterStatesTevFísica (Física)22 Física
