By making the inflaton field the phase of a baryon of SU(N_c) supersymmetric Yang-Mills theory we show that all operators that usually spoil the flatness of the inflationary potential are absent. Our solution naturally generalizes to non-supersymmetric theories.Cosmology of theories beyond the SM | Supersymmetric effective theories; High Energy Physics - Theory; High Energy Physics - Theory; astro-ph.CO; High Energy Physics - Phenomenology[SDGs]SDG8journal article10.1007/JHEP04(2011)0712-s2.0-80053165409http://arxiv.org/abs/1009.3032v1
