Multiparticle one-loop amplitudes and S-duality in closed superstring theory
Michael B. Green, Carlos R. Mafra, Oliver Schlotterer
Explicit expressions for one-loop five supergraviton scattering amplitudes in both type II superstring theories are determined by making use of the pure spinor formalism. The type…
All order alpha'-expansion of superstring trees from the Drinfeld associator
Johannes Broedel, Oliver Schlotterer, Stephan Stieberger +1
We derive a recursive formula for the alpha'-expansion of superstring tree amplitudes involving any number N of massless open string states. String corrections to Yang-Mills field…
Polylogarithms, Multiple Zeta Values and Superstring Amplitudes
Johannes Broedel, Oliver Schlotterer, Stephan Stieberger
A formalism is provided to calculate tree amplitudes in open superstring theory for any multiplicity at any order in the inverse string tension. We point out that the underlying wo…
