Abstract.
Let X be a smooth complete curve, G be a reductive group and \( P \subset G \) a parabolic. Following Drinfeld, one defines a (relative) compactification \( \widetilde{\hbox{\rm Bun}\,}_P \) of the moduli stack of P-bundles on X. The present paper is concerned with the explicit description of the Intersection Cohomology sheaf of \( \widetilde{\hbox{\rm Bun}\,}_P \). The description is given in terms of the combinatorics of the Langlands dual Lie algebra \( \check{\mathfrak g} \).
