Abstract: We study the continuous principal series representations of split connected reductive $ p$-adic groups over $ p$-adic fields. We show that such representations are irreducible when the inducing character lies in a certain cone. This is consistent with a conjecture of Schneider regarding reducibility in the semisimple case.
