Genus Two Surface and Quarter BPS Dyons: The Contour Prescription
Shamik Banerjee, Ashoke Sen, Yogesh K. Srivastava
Following the suggestion of hep-th/0506249 and hep-th/0612011, we represent quarter BPS dyons in N=4 supersymmetric string theories as string network configuration and explore the…
Interpreting the M2-brane Action
Shamik Banerjee, Ashoke Sen
The world-volume theory of multiple M2-branes proposed recently has a free scalar field. For large vev of this scalar field the world-volume action reduces to that of multiple D2-b…
Partition Functions of Torsion >1 Dyons in Heterotic String Theory on T^6
Shamik Banerjee, Ashoke Sen, Yogesh K. Srivastava
The original proposal of Dijkgraaf, Verlinde and Verlinde for the quarter BPS dyon partition function in heterotic string theory on T^6 is known to correctly produce the degeneracy…
Generalities of Quarter BPS Dyon Partition Function and Dyons of Torsion Two
Shamik Banerjee, Ashoke Sen, Yogesh K. Srivastava
We propose a general set of constraints on the partition function of quarter BPS dyons in any N=4 supersymmetric string theory by drawing insight from known examples, and study the…
S-duality Action on Discrete T-duality Invariants
Shamik Banerjee, Ashoke Sen
In heterotic string theory compactified on T^6, the T-duality orbits of dyons of charge (Q,P) are characterized by O(6,22;R) invariants Q^2, P^2 and Q.P together with a set of inva…
Duality Orbits, Dyon Spectrum and Gauge Theory Limit of Heterotic String Theory on T^6
Shamik Banerjee, Ashoke Sen
For heterotic string theory compactified on T^6, we derive the complete set of T-duality invariants which characterize a pair of charge vectors (Q,P) labelling the electric and mag…
