Effective Gravitational Couplings of Kaluza-Klein Gauge Theories
Sujay K. Ashok, Renjan Rajan John, T. J. Layon +2
We study the effective gravitational couplings of four-dimensional Kaluza-Klein compactified gauge theories with eight supercharges. The class of theories we consider are the pure…
Effective Gravitational Couplings of Higher-Rank Supersymmetric Gauge Theories
Renjan Rajan John, Sujoy Mahato, Madhusudhan Raman
When placed on four-manifolds, gauge theories couple to topological invariants of the background via two functions and . General considerations allow…
Renormalisation in -Deformed (Non-)Integrable Theories
Subhroneel Chakrabarti, Arkajyoti Manna, Madhusudhan Raman
That the exact quantum S-matrix of -deformed field theories is known has interesting consequences for their perturbative renormalisation. Recent investigati…
Replicas for Random Matrices
Madhusudhan Raman
We discuss the use of the replica ansatz in computing free energies in random matrix theory, and confirm a conjectured condition on analytic continuation in the replica index at la…
Irrelevant Deformations of Chiral Bosons
Subhroneel Chakrabarti, Divyanshu Gupta, Arkajyoti Manna +1
We study deformations of chiral bosons using the formalism due to Sen. For arbitrary numbers of left- and right-chiral bosons, we find that the $ \t…
Virasoro blocks and quasimodular forms
Diptarka Das, Shouvik Datta, Madhusudhan Raman
We analyse Virasoro conformal blocks in the regime of heavy intermediate exchange . For the 1-point block on the torus and the 4-point block on the sphere…
