Inflationary scenario in the supersymmetric economical 3-3-1 model

Understand

We construct the supersymmetric economical 3-3-1 model which contains inflationary scenario and avoids the monopole puzzle.

• Based on the spontaneous symmetry breaking pattern (with three steps), the $F$-term inflation is derived.
• The slow-roll parameters $\ep$ and $\eta$ are calculated.
• By imposing as experimental five-year WMAP data on the spectral index $n$, we have derived a constraint on the number of e-folding $N_Q$ to be in the range from 25 to 50.
