The LHC Pomeron and Unification of the Standard Model - a Bound-State S-Matrix Within a Fixed-Point Field Theory ?

Abstract

The Critical Pomeron solution of high-energy unitarity leads to a unique underlying massless field theory that might be the origin of the Standard Model. A color sextet quark sector - producing both electroweak symmetry breaking and dark matter - is added to QCD to saturate asymptotic freedom. The sextet sector is then embedded uniquely in ``QUD'' - an anomaly free, just asymptotically free, massless SU(5) theory with elementary lepton and triplet quark sectors very close to the Standard Model. A multi-regge bound-state S-Matrix is constructed using infra-red divergent scaling reggeon interactions that couple via massless fermion chiral anomalies. Within the QCD sub-sector there is an ``anomalous wee gluon'' critical phenomenon that produces a spectrum with confinement and chiral symmetry breaking. The exponentiation of left-handed gauge boson divergences implies that the full set of composite interactions and the low-mass spectrum of QUD could be just those of the Standard Model. All particles, including neutrinos, appear as massive, Goldstone boson related, bound-states and there is no Higgs field. The different coupling strengths, multiple mass scales, and multigenerational structure should also appear. The Critical Pomeron may be the S-Matrix manifestation of the underlying fixed-point field theory. If QUD underlies the Standard Model as described, the sextet sector should produce new, unmistakeable, large cross-sections at the LHC, for which the pomeron could be the main diagnostic!
