All-Orders Classical Soft Graviton Theorems in the Newtonian Limit and Beyond
Debanjan Karan, Babli Khatun, Raghu Mahajan +2
The classical soft graviton theorem aims to determine certain terms in the early- and late-time tails of the gravitational waveform produced in a scattering process, using only the…
All Order Classical Electromagnetic Soft Theorems
Debanjan Karan, Babli Khatun, Biswajit Sahoo +1
If a set of charged objects collide in space and the fragments disperse, then this process will emit electromagnetic waves. Classical soft photon theorem determines the constant te…
Universality of Loop Corrected Soft Theorems in 4d
Hare Krishna, Biswajit Sahoo
In \cite{1808.03288}, logarithmic correction to subleading soft photon and soft graviton theorems have been derived in four spacetime dimensions from the ratio of IR-finite S-matri…
Bootstrapping the -anomaly in QFTs
Denis Karateev, Jan Marucha, João Penedones +1
We study gapped 4d quantum field theories (QFTs) obtained from a relevant deformation of a UV conformal field theory (CFT). For simplicity, we assume the existence of a $\mathbb{Z}…
Spin Dependent Gravitational Tail Memory in
Debodirna Ghosh, Biswajit Sahoo
We derive the leading spin-dependent gravitational tail memory, which appears at the second post-Minkowskian (2 PM) order and behaves as for large retarded time . This…
Classical Soft Graviton Theorem Rewritten
Biswajit Sahoo, Ashoke Sen
Classical soft graviton theorem gives the gravitational wave-form at future null infinity at late retarded time for a general classical scattering. The large expansion has…
Classical Sub-subleading Soft Photon and Soft Graviton Theorems in Four Spacetime Dimensions
Biswajit Sahoo
Classical soft photon and soft graviton theorems determine long wavelength electromagnetic and gravitational waveforms for a general classical scattering process in terms of the el…
Subleading Soft Theorem for arbitrary number of external soft photons and gravitons
Sayali Atul Bhatkar, Biswajit Sahoo
We obtain the subleading soft theorem for a generic theory of quantum gravity, for arbitrary number of soft photons and gravitons and for arbitrary number of finite energy particle…
Classical and Quantum Results on Logarithmic Terms in the Soft Theorem in Four Dimensions
Biswajit Sahoo, Ashoke Sen
We explore the logarithmic terms in the soft theorem in four dimensions by analyzing classical scattering with generic incoming and outgoing states and one loop quantum scattering…
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…
