“…Consider first the case of fundamental strings intersecting R-R branes. Here, we are stymied by our lack of understanding of fundamental strings in R-R backgrounds 8 . However, in the supergravity regime, either the curvature in string units or the dilaton becomes large near the core of the R-R branes.…”

The search for intersecting brane solutions in supergravity is a large and profitable industry. Recently, attention has focused on finding localized forms of known 'delocalized' solutions. However, in some cases, a localized version of the delocalized solution simply does not exist. Instead, localized separated branes necessarily delocalize as the separation is removed. This phenomenon is related to black hole no-hair theorems, i.e. 'baldness.' We continue the discussion of this effect and describe how it can be understood, in the case of Dirichlet branes, in terms of the corresponding intersection field theory. When it occurs, it is associated with the quantum mixing of phases and lack of superselection sectors in low dimensional field theories. We find surprisingly wide agreement between the field theory and supergravity both with respect to which examples delocalize and with respect to the rate at which this occurs. March, 19991

“…Cosmological constants can also be obtained directly in supergravity theories by suitably chosen gaugings of its global symmetries [25]. In fact, it turns out that the results of the Scherk-Schwarz reduction can be recaptured by such gaugings in lower dimensions [26].…”

We show that a class of extremal four-dimensional supersymmetric "highbranes", i.e. string and domain wall solutions, can be interpreted as intersections of four ten-dimensional Dirichlet branes. These d = 4 solutions are related, via T -duality in ten dimensions, to the four-dimensional extremal Maxwell/scalar black holes that are characterized by a scalar coupling parameter a with a = 0, 1/ √ 3, 1, √ 3.

“…The possibility of a 9-brane in M-theory has also been discussed in [24,54]. In section 8, the effective world-volume theories describing the collective coordinates for all branes, including G-branes, are found, with supersymmetry implying that the KK monopole has less translational zero-modes than might have been expected naively.…”

It is argued that D = 10 type II strings and M-theory in D = 11 have D − 5 branes and 9-branes that are not standard p-branes coupled to anti-symmetric tensors. The global charges in a D-dimensional theory of gravity consist of a momentum P M and a dual D − 5 form charge K M1...MD−5 , which is related to the NUT charge. On dimensional reduction, P gives the electric charge and K the magnetic charge of the graviphoton. The charge K is constructed and shown to occur in the superalgebra and BPS bounds in D ≥ 5, and leads to a NUT-charge modification of the BPS bound in D = 4. K is carried by Kaluza-Klein monopoles, which can be regarded as D − 5 branes. Supersymmetry and U-duality imply that the type IIB theory has (p, q) 9-branes. Orientifolding with 32 (0,1) 9-branes gives the type I string, while modding out by a related discrete symmetry with 32 (1,0) 9-branes gives the SO(32) heterotic string. Symmetry enhancement, the effective world-volume theories and the possibility of a twelve dimensional origin are discussed.
