Hybrid Inflation in Supergravity with $(SU(1,1)/U(1))^{m}$ Kähler Manifolds
In the presence of fields without superpotential but with large vevs through D-terms the mass-squared of the inflaton in the context of supergravity hybrid inflation receives positive contributions which could cancel the possibly negative K{ä}hler potential ones. The mechanism is demonstrated using...
