SupersymmetricSU(5) model with four light Higgs doublets

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

We show that a supersymmetricSU(5) grand unified model with four light Higgs doublets, a light colour octet, an electroweak triplet and two singlets predicts the correct value of sin2θw. Moreover it is possible to obtain the ratios mb (mb)/mΤ and ms(l GeV)/mΜ in agreement with experiments provided the Yukawa coupling constants for the second generations are relatively big.
