This `inverted' hybrid inflation has a spectral index $ n < 1 $, in contrast with ordinary hybrid inflation which has $ n \gtrsim 1 $, so a measured value of $n$ substantially different from 1 would distinguish the two. Other generalisations of hybrid inflation are also considered.9 pagesHigh Energy Physics - PhenomenologyAstrophysicsGeneral Relativity and Quantum Cosmologytext
