Abstract
Let be a quadratic extension of non-Archimedean local fields with odd residual characteristic. In this paper, we give equivalent conditions for a simple supercuspidal representation of to be distinguished by in terms of its defining maximal simple type and twisted gamma factors. Furthermore, we prove that the collection of twisted gamma factors evaluated at between and all unitary, tamely ramified quasi-characters of that are trivial on is sufficient to determine whether is distinguished by .
