Multiscalar p-brane solitons

In a previous paper,(10) supersymmetric p-brane solutions involving one dilatonic scalar field in maximal supergravity theories were classified. Although these solutions involve a number of participating field strengths, they are all equal and thus they carry equal electric or magnetic charges. In this paper, we generalize all these solutions to multiscalar solutions in which the charges become independent free parameters. The mass per unit p volume is equal to the sum of these Page charges. We find that for generic values of the Page charges, they preserve the same fraction of the supersymmetry as in their single scalar limits.
