Dynamically induced topological inflation

We propose an inflation model in which the inflationary era is driven by strong dynamics of $Sp(2)$ gauge theory. The quark condensation confined phase theory generates inflaton potential comparable to energy thermal bath at time transition. Afterwards, with a super-Planckian field value global minimum, commences false vacuum region lying between true regions and hence name ``topological inflation.'' Featured huge separation scale ($V(0{)}^{1/4}\ensuremath{\sim}{10}^{15}\text{ }\text{ }\mathrm{GeV}$) minimum (${\ensuremath{\phi}}_{\mathrm{min}}\ensuremath{\sim}{M}_{P}$), can be consistent cosmic microwave background (CMB) observables without suffering from initial condition problems. Crucially, this achieved only some mild tuning parameters $V(\ensuremath{\phi})$. In addition $Sp(2)$, based on anomaly free ${Z}_{6R}$ discrete $R$ symmetry. Remarkably, while all are fixed CMB observations, predicts hierarchy scales including scale, supersymmetry-breaking R-symmetry breaking Higgsino mass right-handed neutrino given terms dynamical $Sp(2)$.
