Quantization of P-branes, D-p-branes and M-branes *
Killing spinors of space-time BPS configurations play an important role in quantization of theories with the fermionic worldvolume local symmetry. We show here how it works for the GS superstring, BST supermembrane and M-5-brane. We show that the non-linear generalization of the (2,0) d=6 tensor supermultiplet action is the M-5-brane action in a Killing gauge. For D-p-branes the novel feature o...
متن کاملp–BRANES, D–BRANES AND M–BRANES
We consider solutions to the string effective action corresponding to p–Branes, D–Branes and M –Branes and discuss some of their properties.
متن کاملMatroids and P-branes
A link between matroid theory and p-branes is discussed. The Schild type action for p-branes and matroid bundle notion provide the two central structures for such a link. We use such a connection to bring the duality concept in matroid theory to p-branes physics. Our analysis may be of particular interest in M-theory and in matroid bundle theory.
متن کاملDyonic P-branes from Self-dual (p+1)-branes
The 'electromagnetic' Sl(2; Z) duality group in spacetime dimension D = 4k can be given a Kaluza-Klein interpretation in D = 4k + 2 as the modular group of a compactifying torus. We show how dyonic 2(k − 1)-branes in D = 4k can be interpreted as self-dual (2k − 1)-branes in D = 4k + 2 wound around the homology cycles of the torus. In particular, dyons of the D=4 N=4 heterotic string theory are ...
متن کاملThe Size of p-Branes
We obtain form factors for scattering of gravitons and anti-symmetric tensor particles off Dirichlet p-branes in Type II superstring theory. As expected, the form factor of the −1brane (the D-instanton) exhibits point-like behavior: in fact it is saturated by the dilaton tadpole graph. In contrast, p-branes with p > −1 acquire size of order the string scale due to quantum effects and exhibit Re...
