一种对合的眶状MSSM

An involuted orbifold MSSM

Patrick K. S. Vaudrevange

摘要:

本文给出了Z_2 × Z_2轨道上E_8 × E_8杂种优势串的一个紧化。该模型再现了具有物质宇称和非平凡Yukawa结构的精确手征MSSM谱。关键成分是与对合相关联的自由作用的威尔逊线,将SU(5)分裂为SU(3)x SU(2)x U(1)_Y。这项工作是基于在“第九届希腊学校和基本粒子物理学和引力研讨会”上的演讲,并回顾了与M。布拉什奇克Groot Nibbelink,M. Ratz,F. Ruehle和M.特拉普莱蒂

英文摘要:

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.
