Pinching rules in the chiral-splitting description of one-loop string amplitudes
Filippo Maria Balli, Alex Edison, Oliver Schlotterer
Loop amplitudes in string theories reduce to those of gauge theories and (super)gravity in their worldline description as the inverse string tension tends to zero. The appeara…
Basis decompositions of genus-one string integrals
Carlos Rodriguez, Oliver Schlotterer, Yong Zhang
One-loop scattering amplitudes in string theories involve configuration-space integrals over genus-one surfaces with coefficients of Kronecker-Eisenstein series in the integrand. A…
Cyclic products of higher-genus Szegö kernels, modular tensors and polylogarithms
Eric D'Hoker, Martijn Hidding, Oliver Schlotterer
A wealth of information on multiloop string amplitudes is encoded in fermionic two-point functions known as Szegö kernels. In this paper we show that cyclic products of any number…
Constructing polylogarithms on higher-genus Riemann surfaces
Eric D'Hoker, Martijn Hidding, Oliver Schlotterer
An explicit construction is presented of homotopy-invariant iterated integrals on a Riemann surface of arbitrary genus in terms of a flat connection valued in a freely generated Li…
Cyclic products of Szegö kernels and spin structure sums I: hyper-elliptic formulation
Eric D'Hoker, Martijn Hidding, Oliver Schlotterer
The summation over spin structures, which is required to implement the GSO projection in the RNS formulation of superstring theories, often presents a significant impediment to the…
Perfecting one-loop BCJ numerators in SYM and supergravity
Alex Edison, Song He, Henrik Johansson +3
We take a major step towards computing -dimensional one-loop amplitudes in general gauge theories, compatible with the principles of unitarity and the color-kinematics duality.…
