Our results are in perfect agreement with the predictions based on S-duality, mirror symmetry and supersymmetry. %G English %2 https://hal.science/hal-03394606/document %2 https://hal.science/hal-03394606/file/Alexandrov2021_Article_EuclideanD-branesInTypeIIBStri.pdf %L hal-03394606 %U https://hal.science/hal-03394606 %~ CNRS %~ L2C %~ MIPS %~ UNIV-MONTPELLIER %~ TEST-HALCNRS %~ UM-2015-2021
