Background Independence of Closed Superstring Field Theory
Ashoke Sen
Given a family of world-sheet superconformal field theories related by marginal deformation, we can formulate superstring field theory based on any of these world-sheet theories. B…
Testing Subleading Multiple Soft Graviton Theorem for CHY Prescription
Subhroneel Chakrabarti, Sitender Pratap Kashyap, Biswajit Sahoo +2
In arXiv:1707.06803 we derived the subleading multiple soft graviton theorem in a generic quantum theory of gravity for arbitrary number of soft external gravitons and arbitrary nu…
Subleading Soft Theorem for Multiple Soft Gravitons
Subhroneel Chakrabarti, Sitender Pratap Kashyap, Biswajit Sahoo +2
We derive the subleading soft graviton theorem in a generic quantum theory of gravity for arbitrary number of soft external gravitons and arbitrary number of finite energy external…
Sub-subleading Soft Graviton Theorem in Generic Theories of Quantum Gravity
Alok Laddha, Ashoke Sen
We analyze scattering amplitudes with one soft external graviton and arbitrary number of other finite energy external states carrying arbitrary mass and spin to sub-subleading orde…
Subleading Soft Graviton Theorem for Loop Amplitudes
Ashoke Sen
Superstring field theory gives expressions for heterotic and type II string loop amplitudes that are free from ultraviolet and infrared divergences when the number of non-compact s…
Closed Superstring Field Theory and its Applications
Corinne de Lacroix, Harold Erbin, Sitender Pratap Kashyap +2
We review recent developments in the construction of heterotic and type II string field theories and their various applications. These include systematic procedures for determining…
