A One-Loop Test of String Duality
We test type IIA-heterotic string duality in six dimensions by showing that the sigma model anomaly of the heterotic string is generated by a combination of a tree level and a string one-loop correction on the type IIA side.
متن کاملEleven Dimensional Origin of String/string Duality: a One Loop Test
Membrane/fivebrane duality in D = 11 implies Type IIA string/Type IIA fivebrane duality in D = 10, which in turn implies Type IIA string/heterotic string duality in D = 6. To test the conjecture, we reproduce the corrections to the 3-form field equations of the D = 10 Type IIA string (a mixture of tree-level and one-loop effects) starting from the Chern-Simons corrections to the 7-form Bianchi ...
متن کاملPutting String/string Duality to the Test
After simultaneous compactification of spacetime and worldvolume onK3, theD = 10 heterotic fivebrane with gauge group SO(32) behaves like a D = 6 heterotic string with gauge group SO(28)× SU(2), but with Kac–Moody levels different from those of the fundamental string. Thus the string/fivebrane duality conjecture in D = 10 gets replaced by a string/string duality conjecture in D = 6. Since D = 6...
متن کاملDuality-Invariant Gaugino Condensation and One-loop Corrected Kähler Potentials in String Theory
The duality-invariant gaugino condensation with or without massive matter fields is re-analysed, taking into account the dependence of the string threshold corrections on the moduli fields and recent results concerning one-loop corrected Kähler potentials. The scalar potential of the theory for a generic superpotential is also calculated.
متن کاملA Two-loop Test of Buscher’s T-duality I
We study the two loop quantum equivalence of sigma models related by Buscher’s T-duality transformation. The computation of the two loop perturbative free energy density is performed in the case of a certain deformation of the SU(2) principal sigma model, and its T-dual, using dimensional regularization and the geometric sigma model perturbation theory. We obtain agreement between the free ener...
