Non-minimal quartic inflation in supersymmetric \(\mathrm {SO}(10)\). (English) Zbl 1369.83111
Summary: We describe how quartic \((\lambda \phi^4)\) inflation with non-minimal coupling to gravity is realized in realistic supersymmetric \(\mathrm{SO}(10)\) models. In a well-motivated example the \(16 - \overline{16}\) Higgs multiplets, which break \(\mathrm{SO}(10)\) to \(\mathrm{SU}(5)\) and yield masses for the right-handed neutrinos, provide the inflaton field \(\phi\). Thus, leptogenesis is a natural outcome in this class of \(\mathrm{SO}(10)\) models. Moreover, the adjoint (45-plet) Higgs also acquires a GUT scale value during inflation so that the monopole problem is evaded. The scalar spectral index \(n_s\) is in good agreement with the observations and \(r\), the tensor to scalar ratio, is predicted for realistic values of GUT parameters to be of order \(10^{-3} - 10^{-2}\).
