An involuted orbifold MSSM

Abstract

A compactification of the E_8 x E_8 heterotic string on a Z_2 x Z_2 orbifold equipped with an additional freely acting involution is presented. This model reproduces the exact chiral MSSM spectrum with matter parity and a non-trivial Yukawa structure. The key ingredient is a freely acting Wilson line associated to the involution, breaking SU(5) to SU(3) x SU(2) x U(1)_Y. This work is based on a talk given at the "9th Hellenic School and Workshop on Elementary Particle Physics and Gravity" and reviews the results of a collaboration with M. Blaszczyk, S. Groot Nibbelink, M. Ratz, F. Ruehle and M. Trapletti.

To appear in the proceedings of 9th Hellenic School and Workshops on Elementary Particle Physics and Gravity (CORFU 2009), Corfu, Greece, 30 Aug - 20 Sep 2009.
