Massive Scattering Amplitudes in Six Dimensions

Rishabh Jha, Chethan Krishnan, K. V. Pavan Kumar

We show that a natural spinor-helicity formalism that can describe massive scattering amplitudes exists in dimensions. This is arranged by having helicity spinors carry an in…

Bounds on Slow Roll at the Boundary of the Landscape

Sumit K. Garg, Chethan Krishnan, M. Zaid Zaz

We present strong evidence that the tree level slow roll bounds of arXiv:1807.05193 and arXiv:1810.05506 are valid, even when the tachyon has overlap with the volume of the cycle w…

Dark Matter from a Dark Connection

Ranit Das, Chethan Krishnan

In the first part of this note, we observe that a non-Riemannian piece in the affine connection (a "dark connection") leads to an algebraically determined, conserved, symmetric 2-t…

Bounds on Slow Roll and the de Sitter Swampland

Sumit K. Garg, Chethan Krishnan

The recently introduced swampland criterion for de Sitter (arXiv:1806.08362) can be viewed as a (hierarchically large) bound on the smallness of the slow roll parameter . This…

Complete Solution of a Gauged Tensor Model

Chethan Krishnan, K. V. Pavan Kumar

Building on a strategy introduced in arXiv:1706.05364, we present exact analytic expressions for all the singlet eigenstates and eigenvalues of the simplest non-linear ()…

On the KKLT Goldstino

Chethan Krishnan, Himanshu Raj, P. N. Bala Subramanian

We construct general asymptotically Klebanov-Strassler solutions of a five dimensional truncation of IIB supergravity…
