Let π be a simple supercuspidal representation of the symplectic group Sp 2 l(F) , over a p-adic field F. In this work, we explicitly compute the Rankin–Selberg γ-factor of rank-1 twists of π. We then completely determine the Langlands parameter of π, if p≠ 2. In the case that F= Q2, we give a conjectural description of the functorial lift of π, with which, using a recent work of Bushnell and Henniart, one can obtain its Langlands parameter.
