Abstract

We investigate gravitational wave signals in a non-supersymmetric grand unified model where the group SO(10) is broken in two steps to the Standard Model gauge group. We calculate the analytical form of the one-loop effective potential responsible for the first step of symmetry breaking and show that it can lead to a first-order phase transition with gravitational wave production. We also determine the gravitational wave background produced by the primordial plasma of relativistic particles. The present experimental sensitivity is still far from the expected signals, but could be in reach of novel detector concepts.
