The main purpose of this paper is to modify the orbit method for the
Baum-Connes conjecture as developed by Chabert, Echterhoff and Nest in their
proof of the Connes-Kasparov conjecture for almost connected groups
\cite{MR2010742} in order to deal with linear algebraic groups over local
function fields (i.e., non-archimedean local fields of positive
characteristic). As a consequence, we verify the Baum-Connes conjecture for
certain Levi-decomposable linear algebraic groups over local function fields.
One of these is the Jacobi group, which is the semidirect product of the
symplectic group and the Heisenberg group
