Datasets and notebooks for "Precision asymptotics of string amplitudes"

Data and computational notebooks (Mathematica) for the preprint ``Precision asymptotics of string amplitudes’’ by M. M. Baccianti, L. Eberhardt and S. Mizera. The submission contains numerical data of the one-loop four-point scattering of gravitons in type II string theory. The respository contains the following notebooks and data: For X \in \{ImA, ImDResA, ReDResA\}, the file code/X.nb produces the data stored in data/X that computes the one-loop four-graviton string amplitude in type II string theory as described in the paper. The data data/ReA was computed using the C++ program StringQMC available as an ancillary file in https://arxiv.org/abs/2507.22105. Let us describe the data formats: - data/ImA contains files of the format poq_s0-smax.txt where smax indicate the maximum value of smax and p/q is the fixed ratio -t/s. As described in the paper, it is convenient for the numerical analysis to have data for rational ratios. These files contain a list whose first entry is the value of s and the second entry is the value of the imaginary part of the amplitude. - data/ImDResA contains files of the format simn.m where n is a number giving the value of s. They contain the decay width of the s-th mass level, which is a polynomial in t of degree 2s-2. Each decay width is further subdivided into the contributions from different internal mass-levels mD and mU. For mD
