Pion scattering: from Lovelace-Shapiro to Neveu-Schwarz and beyond
<!--HTML-->We show how to embed the Lovelace-Shapiro model for pion scattering in the Neveu-Schwarz fermionic string. In particular we relate the 4-point pion amplitude exposing Adler’s zero to a peculiar 4-point tachyon amplitude. We then show how to compute higher point amplitudes involving...
