On the change of root numbers under twisting and applications

The purpose of this article is to show how the root number of a modular form changes by twisting in terms of the local Weil-Deligne representation at each prime ideal. As an application, we show how one can, for each odd prime p, determine whether a modular form (or a Hilbert modular form) with triv...
