Can thermal inflation solve the monopole problem ?
R. Jeannerot
Abstract
It is shown that thermal inflation arises naturally in rank greater than five unified theories when non-renormalisable terms are introduced. Thermal inflation is driven by two Higgs fields ΦB-L and ΦB-L which also break U(1)B-L when acquiring vevs at the end of inflation. The inflationary period provides enough e-foldings to solve the monopole problem for MB-L ≥ 1012 GeV. We point out that observations suggest that MB-L 1014 GeV.
