On-Shell Action for Type IIB Supergravity and Superstrings on
Subhroneel Chakrabarti, Divyanshu Gupta, Arkajyoti Manna
AdS/CFT predicts that the value of the on-shell action for type IIB Supergravity (SUGRA) on background must be a non-zero number completely determined from the b…
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…
Chiral Decoupling from Irrelevant Deformations
Subhroneel Chakrabarti, Madhusudhan Raman
We show that at the level of the equations of motion (i.e. classically), in the limit in which the deformation parameter is sent to infinity, the le…
Generalised Garfinkle-Vachaspati Transform With Dilaton
Subhroneel Chakrabarti, Deepali Mishra, Yogesh K. Srivastava +1
The generalised Garfinkle-Vachaspati transform (GGV) introduced in our previous work (arXiv:1808.04981) is a powerful technique to add hair modes to a class of known D1-D5 solution…
Amplitudes Involving Massive States Using Pure Spinor Formalism
Subhroneel Chakrabarti, Sitender Pratap Kashyap, Mritunjay Verma
Same amplitudes evaluated independently using RNS and pure spinor formalism are expected to agree. While for massless states, this fact has been firmly established, for massive sta…
Integrated Massive Vertex Operator in Pure Spinor Formalism
Subhroneel Chakrabarti, Sitender Pratap Kashyap, Mritunjay Verma
We construct the integrated vertex operator for the first massive states of open superstrings with in the pure spinor formalism of the superstring theory. This vert…
