General analysis of corrections to the standard seesaw formula in grand unified models

  • 1. Bartol Research Institute, University of Delaware, Newark, Delaware 19716 (United States)

Description

In realistic grand unified models there are typically extra vectorlike matter multiplets at the GUT-scale that are needed to explain the family hierarchy. These contain neutrinos that, when integrated out, can modify the usual neutrino seesaw formula. A general analysis is given. It is noted that such modifications can explain why the neutrinos do not exhibit a strong family hierarchy like the other types of fermions
