Hi all,

I was thinking about doing my project on ways to get (close to) real world physics from string theory. Starting from the 10D E8xE8 Heterotic string theory and compactifying the extra dimensions onto a Calabi-Yau 3-fold you can 4D spacetime physics in the string theory framework. In my project I was going to look at how this massive gauge bundle is broken and how the geometry determines the particle physics spectra in some, hopefully, “simple” examples.
