Using an exact supergravity solution representing the Dp− D̄p system, it is demonstrated that one can construct a supergravity analogue of the tachyon potential. Remarkably, the (regularized) minimum value of the potential turns out to be V (T0) = −2m with m denoting the ADM mass of a single Dp-brane. This result, in a sense, appears to confirm that Sen’s… (More)
