Soft and Collinear Limits in $N = 8$ Supergravity using Double Copy Formalism

Nabamita Banerjee, Tabasum Rahnuma, Ranveer Kumar Singh

It is known that $N = 8$ supergravity is dual to $N = 4$ super Yang-Mills (SYM) via the double copy relation. Using the explicit relation between scattering amplitu…

JT gravity from holographic reduction of 3D asymptotically flat spacetime

Arindam Bhattacharjee, Muktajyoti Saha

We attempt to understand the CFT $_{1}$ structure underlying (2+1)D gravity in flat spacetime via dimensional reduction. We observe that under superrotation, the hyperbolic (and dS$_2…

Gravitational Quadratic-in-Spin Hamiltonian at NNNLO in the post-Newtonian framework

Manoj K. Mandal, Pierpaolo Mastrolia, Raj Patil +1

We present the result of the quadratic-in-spin interaction Hamiltonian for binary systems of rotating compact objects with generic spins, up to NNNLO corrections within the post-Ne…

Logarithmic correction to black hole entropy in universal low-energy string theory models

Sudip Karan, Gurmeet Singh Punia

We calculate the logarithmic correction to the entropy of asymptotically flat and AdS black holes (rotating, non-rotating, charged, and uncharged) embedded in Einstein-Maxwell-dila…

$1/ L^{2}$ corrected soft photon theorem from a CFT $_{3}$ Ward identity

Nabamita Banerjee, Karan Fernandes, Arpita Mitra

Classical soft theorems applied to probe scattering processes on AdS $_{4}$ spacetimes predict the existence of $1/ L^{2}$ corrections to the soft photon and soft graviton factors of asy…

On-shell Supersymmetry and higher-spin amplitudes

Mahesh K. N. Balasubramanian, Kushal Chakraborty, Arnab Rudra +1

We use on-shell Supersymmetry to constrain the three-point function of two massless particles and one massive particle in 3+1 dimensions. We use this information to write down the…

Gravitational Spin-Orbit Hamiltonian at NNNLO in the post-Newtonian framework

Manoj K. Mandal, Pierpaolo Mastrolia, Raj Patil +1

We present the result of the spin-orbit interaction Hamiltonian for binary systems of rotating compact objects with generic spins, up to NNNLO corrections within the post-Newtonian…

String Theory Corrections to Holographic Black Hole Chemistry

Suvankar Dutta, Gurmeet Singh Punia

The connection between the bulk and the boundary first law of thermodynamics in adS space has been discussed in generic higher derivative gravity. String theory corrections to the…

Local momentum space: Scalar field and gravity

Sukanta Panda, Abbas Altafhussain Tinwala, Archit Vidyarthi

We use the local momentum space technique to obtain an expansion of the Feynman propagators for scalar field and graviton up to first order in the background curvature. The express…

Scattering Amplitudes and BCFW in $N = 2^{*}$ Theory

Md. Abhishek, Subramanya Hegde, Dileep P. Jatkar +1

We use massive spinor helicity formalism to study scattering amplitudes in $N = 2^{*}$ super-Yang-Mills theory in four dimensions. We compute the amplitudes at an arbitrary p…

Supersymmetrization of deformed BMS algebras

Nabamita Banerjee, Arpita Mitra, Debangshu Mukherjee +1

$W (a, b)$ and $W (a, b; a ˉ, b ˉ)$ algebras are deformations of $bms_{3}$ and $bms_{4}$ algebra respectively. We present an $N = 2$ supersymmetric…
