Kaluza-Klein and H-Dyons in String Theory
نویسنده
چکیده
Kaluza-Klein monopole and H-monopole solutions, which are T-dual to each other, are the well-known solutions of string theory compactified on T . Since string theory in this case has an S-duality symmetry, we explicitly construct the corresponding dyonic solutions by expressing the D = 4 string effective action in a manifestly SL(2, R) invariant form with an SL(2, R) invariant constraint. The Schwarz-Sen charge spectrum, the BPS saturated mass formula as well as the stability of these states are discussed briefly. ∗E-mail address: [email protected]

Kaluza-Klein Dyons in String Theory
S-duality of hetertotic / type II string theory compactified on a six dimensional torus requires the existence of Kaluza-Klein dyons, carrying winding charge. We identify the zero modes of the Kaluza-Klein monopole solution which are responsible for these dyonic excitations, and show that we get the correct degeneracy of dyons as predicted by Sduality. The self-dual harmonic two form on the Euc...
متن کاملDivergences in Kaluza – Klein Models and their String
Effective field theories with (large) extra dimensions are studied within a physical regularization scheme provided by string theory. Explicit string calculations then allow us to consistently analyze the ultraviolet sensitivity of Kaluza–Klein theories in the presence or absence of low energy supersymmetry.
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 ...

We study the dyonic charge of type IIA D6-branes interpreted as M-theory Kaluza-Klein monopoles. The connection between the dyonic properties of type IIA D6-branes and the existence of eleven dimensions is discussed. We also study dyonic properties of noncommutative monopoles. Variations of the external antisymmetric B-field generate the electric charge of non-commutative dyons. E-mail: cesar.g...
متن کاملUnwinding Strings and T-duality of Kaluza-Klein and H-Monopoles
A fundamental string with non-zero winding number can unwind in the presence of a Kaluza-Klein monopole. We use this fact to deduce the presence of a zero mode for the Kaluza-Klein monopole corresponding to excitations carrying H-electric charge and we study the coupling of this zero mode to fundamental strings. We also a describe a T-dual process in which the momentum of a fundamental string “...
