Title: Physical Yukawa Couplings in Heterotic String Compactifications

Abstract: Calabi-Yau compactifications of the $E_8\times E_8$ heterotic string provide a promising route to recovering the four-dimensional particle physics described by the Standard Model. While the topology of the Calabi-Yau space determines the overall matter content in the low-energy effective field theory, further details of the compactification geometry are needed to calculate the normalized physical couplings and masses of elementary particles. In this talk, we present novel numerical techniques for computing physically normalized Yukawa couplings in a number of heterotic models in the standard embedding using machine learning. We observe that the results produced using these techniques are in excellent agreement with the expected values.
