“…Previous arguments either used particular values of the intercept of the Regge trajectories as originally proposed in ref. [15] (see also [16]) along with the Virasoro algebra in the elimination of negative norm states [17][18][19] or employed the solution of the integral corresponding to the four-point function in terms of the Euler Beta function [16,20]. To the best of our knowledge, getting the value of the critical dimension without making explicit reference to the Virasoro algebra (or Lorentz invariance in particular gauges) is a new feature stemming from the chiral bosonic string.…”

Abstract:We compute the scattering amplitudes of four massless states for chiral (closed) bosonic and type II superstrings using the Kawai-Lewellen-Tye (KLT ) factorization method. The amplitude in the chiral bosonic case is identical to a field theory amplitude corresponding to the spin-2 tachyon, massless gravitational sector and massive spin-2 tardyon states of the spectrum. Chiral type II superstrings amplitude only possess poles associated with the massless gravitational sector. We briefly discuss the extension of the calculation to heterotic superstrings.

“…The class of dual models called dual amplitudes with Mandelstam analyticity (DAMA) [3] is a generalization of Veneziano amplitudes [8] to the most general form consistent with Mandelstam analyticity. (DAMA has the Veneziano limit α(t) ∼ t, but the transition to this limit occurs discontinuously [9].)…”

We apply a phenomenological approach based on nonlinear Regge trajectories to glueball states.The parameters, i.e., intercept and threshold, or trajectory termination point beyond which no bound states should exist, are determined from pomeron (scattering) data. Systematic errors inherent to the approach are discussed. We then predict masses of glueballs on the tensor trajectory.For comparison, the approach is applied to available quenched lattice data. We find a discrepancy between the lattice based thresholds and the pomeron threshold that we extract from data.

“…Scattering amplitudes are perhaps the most basic quantities computed in any QFT, and string amplitudes are in fact older than string theory itself [74,75]. In 1968, G. Veneziano constructed a "dual" four point scattering amplitude with particular crossing symmetries in order to describe hadron scattering.…”

This review is concerned with scattering amplitudes in open superstring theories. In particular, we introduce two different formalisms to compute tree level amplitudes – the Ramond Neveu Schwarz‐ (RNS‐) and the Pure Spinor (PS‐) formalism. The RNS approach proves to be flexible in describing compactifications from ten to four flat spacetime dimensions. We solve the technical problems due to the underlying interacting conformal field theory on the worldsheet. This is exploited to extract phenomenologically relevant scattering amplitudes of gluons and quarks as well as production‐ and decay rates of massive vibration modes which have already been identified as virtual exchange particles at the massless level. In case of a TeV string scale, string specific signatures in parton collisions might be observed at the LHC experiment in the near future and constitute the first experimental evidence for string theory. These statements apply to a wide class of string vacua and therefore bypass the so‐called landscape problem of string theory. The PS formalism allows for a manifestly supersymmetric treatment of scattering amplitudes in ten spacetime dimensions with sixteen supercharges. We introduce a family of superfields which arises in tree amplitudes of massless open string states and can be naturally identified with diagrams made of cubic vertices. We firstly achieve a compact superspace representation of multiparticle field theory amplitudes and moreover express the complete n point superstring amplitude as a minimal linear combination of partial field theory amplitudes and hypergeometric functions. The latter carry the stringy effects and are analyzed from different perspectives.
