Superstring amplitudes, unitarily, and Hankel determinants of multiple zeta values
Abstract The interplay of unitarity and analyticity has long been known to impose strong constraints on scattering amplitudes in quantum field theory and string theory. This has been highlighted in recent times in a number of papers and lecture notes. Here we examine such conditions in the context o...
