Thermal inflation and the moduli problem
Thermal inflation and the moduli problem
In supersymmetric theories a field can develop a vacuum expectation value M\ensuremath{\gg}${10}^{3}$ GeV, even though its mass m is of order ${10}^{2}$ to ${10}^{3}$ GeV. The finite temperature in the early Universe can hold such a field at zero, corresponding to a false vacuum with an energy density ${\mathit{V}}_{0}$\ensuremath{\sim}${\mathit{m}}^{2}$${\mathit{M}}^{2}$.
