String from Veneziano model
This article is about my memories from the discovery[1, 2, 3, 4] that the Veneziano model[5] described in fact interacting strings. I came to the understanding that the dual or Veneziano model is really a model of strings independently of Susskind[3] and Nambu[4]. A characteristic feature of my approach [1, 2] was that I used thinking of very high order “fishnet” or planar Feynman diagrams as t...
متن کاملHadron pair photoproduction within the Veneziano model
We first suppose that low-energy hadron pair photoproduction reactions γ(∗)γ(∗) → hh̄ are dominated by s-channel resonance contributions. Their normalization is then calculated by their correspondence with the Reggeon term in the Regge parametrization of the γh total cross sections. For the case of pp̄, we make use of the measured γp total cross section, and for the case of K+K−, we make use of t...
متن کاملnN Backward Scattering
nN backward scattering data above 5 GeV /c are analyzed in terms of the baryon Regge pole exchange and accompanying Regge cut due to the strong absorption. The fit of the cross sections is reasonable. The role of the cut turns out to be very important: (1) The extrapolated magnitude of the L10 residue at a 4 =! is significantly larger than that without the cut. Ll0 residue with or without the w...
متن کاملAnalysis of Meson-baryon Scattering Processes Related by Su(3) in a Unitarized Veneziano Model*
We extend a previously developed eikonal-like model to analyze meson-baryon scattering. Unitarity is partly described by introducing all the coupled two-particle channels which are related to each other by the requirements of SU(3), duality, factorization and absence of exotics 0 The Pomeron is interpreted as the manifestation of multiparticle unitarity rather than as a t-channel Regge exchange...
متن کاملWITTEN–VENEZIANO from GREEN–SCHWARZ
We consider the U(1) problem within the AdS/CFT framework. We explain how the Witten–Veneziano formula for the η mass is related to a generalized Green–Schwarz mechanism. The closed string mode, that cancels the anomaly of the gauged U(1) axial symmetry, is identified with the η meson. In a particular set-up of D3-branes on a C/(Z3 ⊗ Z3) orbifold singularity, the η ′ meson is a twisted-sector R...
