Phys.) as part of AnLy Strings and Fields online s eminars\n\n\nAbstract\nWe present a numerical computation\, based on neura l network techniques\, of the physical Yukawa couplings in a heterotic str ing theory model obtained by compactifying on a smooth Calabi-Yau threefol d. The model in question is one of a large class of heterotic line bundle models with precisely the MSSM low-energy spectrum plus fields uncharged u nder the standard-model group. The relevant quantities\, that is\, the Ric ci-flat Calabi-Yau metric\, the Hermitian Yang-Mills bundle metrics and th e harmonic bundle-valued forms\, are all computed by training suitable neu ral networks. The calculation is carried out at several points along one-p arameter family in complex structure moduli space\, and each complete calc ulation takes about half a day on a laptop. The methods presented here gen eralise to other string models and constructions\, including to F-theory m odels.\n LOCATION:https://researchseminars.org/talk/AnLy/40/ END:VEVENT END:VCALENDAR
