Understand

We consider a class of multi-component hybrid inflation models whose evolution may be analytically solved under the slow-roll approximation.

We call it multi-brid inflation (or $n$-brid inflation where $n$ stands for the number of inflaton fields).
As an explicit example, we consider a two-brid inflation model, in which the inflaton potentials are of exponential type and a waterfall field that terminates inflation has the standard quartic potential with two minima.
Using the $\delta N$ formalism, we derive an expression for the curvature perturbation valid to full nonlinear order.
