Liouville/Toda central charges from M5-branes
We show that the central charge of the Liouville and ADE Toda theories can be reproduced by equivariantly integrating the anomaly eight-form of the corresponding six-dimensional N = (0, 2) theories, which describe the low-energy dynamics of M5-branes.
متن کاملBranes, central charges and U-duality invariant BPS conditions
In extended supergravity theories there are p-brane solutions preserving different numbers of supersymmetries, depending on the charges, the spacetime dimension and the number of original supersymmetries (8, 16 or 32). We find U-duality invariant conditions on the quantized charges which specify the number of supersymmetries preserved with a particular charge configuration. These conditions rel...
متن کاملPara-Liouville/Toda central charges from M5-branes
We propose that N M5-branes, put on R/Zm with deformation parameters ǫ1,2, realize two-dimensional theory with ŜU(m)N symmetry and m-th para-WN symmetry. This includes the standard WN symmetry for m = 1 and super-Viraroro symmetry for m = N = 2. We provide a small check of this proposal by calculating the central charge of the 2d theory from the anomaly polynomial of the 6d theory. ∗on leave fr...
متن کاملGravitational Duality , Branes and Charges
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 ch...
متن کاملCharges of Exceptionally Twisted Branes
The charges of the exceptionally twisted (D4 with triality and E6 with charge conjugation) D-branes of WZW models are determined from the microscopic/CFT point of view. The branes are labelled by twisted representations of the affine algebra, and their charge is determined to be the ground state multiplicity of the twisted representation. It is explicitly shown using Lie theory that the charge ...
