Understand

We study the possible range of the tilt $n_s$ and the tensor-to-scalar ratio $r$ in multifield versions of a class of inflationary models from string theory.

We show that $r$ is the same between the single field models and multifield models while $n_s$ is bounded above by the results of single field models.
Below its maximum value, $n_s$ depends on the specific distributions of parameters in the model.
The general trend is that the wider the distributions are, the smaller $n_s$ is.
