Query: Radiative corrections to the Casimir effect for the massive scalar field   We compute the $O(\lambda)$ correction to the Casimir energy for the massive
$\lambda\phi^4$ model confined between a pair of parallel plates. The
calculations are made with Dirichlet and Neumann boundary conditions. The
correction is shown to be sensitive to the boundary conditions, except in the
zero mass limit, in which case our results agree with those found in the
literature.
