What's the best model of inflation? Give me your vote, please

Click For Summary
The discussion centers on the preference for hybrid inflation as the best model of inflation. Hybrid inflation involves the interaction between two scalar fields, the inflaton and the Higgs field, leading to a first-order phase transition. Variants of this model include polynomial, tilted, and supersymmetric hybrid inflation. The original poster acknowledges an oversight in not including chaotic inflation in the poll options. Additionally, the concept of a "firework universe" is introduced as a potential inflation model that could explain dark matter.

how about describing hybrid inflation for us?
BTW in This Week's Finds #202 that just came out (you may have seen it on SPR) John Baez puts this riddle (about halfway down the post)
What is this sequence?
un, dos, tres, quatre, cinc, seis, set, vuit, nou, deu,...
You should know since you come from Barcelona

Is inflation driven by two real scalar fields (the inflaton and the Higgs field). They interact between them, so first the inflaton is slowly rolling through its potential, and then triggers the rolling of the Higgs field, that undergoes a fast rolling. Inflation ends in a first order phase transition.
It was proposed by D.Linde in 1991, though the paper is not online
Some variants of the model are polynomial hybrid inflation, tilted hybrid inflation, and supersymmetric hybrid inflation
Soon after I sent the poll, I realized my great mistake of not including chaotic inflation in the options. I tried to edit the poll, but was impossible. bad luck. It can go in "Other", jointly with other models such Q-ball inflation, extranatural inflation,
D-term inflation or brane-antibrane inflation
Ah, the sequence...It is easy since I speak catalan!But note that Eugene Catalan was not catalan at all, he was belgian!

Firework Universe
The firework universe beginning is one yet to be explored inflation possibility that accounts for the dark matter in the simplest way.

almost missed it due to cloud, didnt see max at 0710 NZST as it went back into cloud.
