Phenomenological constraints on grand unification in superstring-inspired models

  • 1. School of Physics, University of Melbourne, Parkville 3052, Victoria, Australia

Description

From the viewpoint of unification we investigate various superstring-inspired E6 models which feature no intermediate symmetry-breaking scale, and which contain only one extra U(1) low-energy gauge group. Inputting the current experimentally allowed ranges for the coupling constants at the W scale, we show that unification is achieved most readily when the so-called ''survivors'' (particles which do not belong to an ordinary E6 generation) are SU(2) doublets, and is difficult to achieve without them
