| Abstract: | We construct new three-family N = 1 supersymmetric Pati–Salam models from intersecting D6-branes with original gauge group U (4) C × USp (2) L × U (2) R on a Type IIA T 6 / (Z 2 × Z 2) orientifold. We find that replacing a U (2) with a USp (2) group severely restricts the number of three-generation supersymmetric models such that there are only five inequivalent models. Exchanging the left and right sectors, we obtain five dual models with gauge group U (4) C × U (2) L × USp (2) R . These ten models have different gauge coupling relations at string scale. The highest wrapping number is 4, and one of the models contains no filler O6-planes. Moreover, we discuss in detail the particle spectra, the composite particles through strong coupling dynamics, and the exotic particle decouplings. Also, we study how to realize the string-scale gauge coupling relations in some models. [ABSTRACT FROM AUTHOR] |
