Abstract
We develop techniques based on differential geometry to compute holomorphic Yukawa couplings for heterotic line bundle models on CalabiYau manifolds defined as complete intersections in projective spaces It is shown explicitly how these techniques relate to algebraic methods for computing holomorphic Yukawa couplings We apply our methods to various examples and evaluate the holomorphic Yukawa couplings explicitly as functions of the complex structure moduli It is shown that the rank of the Yukawa matrix can decrease at specific loci in complex structure moduli space In particular we compute the up Yukawa coupling and the singletHiggslepton trilinear coupling in the heterotic standard model described in ref 32This article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
