Super - Poincaré Covariant Two - Loop Superstring Amplitudes
The super-Poincaré covariant formalism for the superstring is used to compute mass-less four-point two-loop amplitudes in ten-dimensional superspace. The computations are much simpler than in the RNS formalism and include both external bosons and fermions.
متن کاملUnitarity constraints on chiral perturbative amplitudes
Low lying scalar resonances emerge as a necessary part to adjust chiral perturbation theory to experimental data once unitarity constraint is taken into consideration. I review recent progress made in this direction in a model independent approach. Also I briefly review studies on the odd physical properties of these low lying scalar resonances, including in the γγ → π+π−, π0π0 processes. Low l...
متن کاملConsistency of Super - Poincaré Covariant Superstring Tree Amplitudes Nathan Berkovits
Using pure spinors, the superstring was recently quantized in a manifestly tendimensional super-Poincaré covariant manner and a covariant prescription was given for tree-level scattering amplitudes. In this paper, we prove that this prescription is cyclically symmetric and, for the scattering of an arbitrary number of massless bosons and up to four massless fermions, it agrees with the standard...
متن کاملTheoretical Constraints on Interaction Amplitudes of Light Mesons
We impose unitarity constraints on the S–wave isoscalar ππ amplitudes extracted from the analysis of the π−p → ππn data which have been measured by the CERN–Cracow–Munich collaboration on a transversely polarized target at 17.2 GeV/c π− momentum. Two ”steep” solutions contain a narrow S–wave f0(750) resonance under the ρ(770) and exhibit a considerable inelasticity η which is in disagreement wi...
