Cancellation of Conformal and Chiral Anomalies in supergravities
Renata Kallosh
A cancellation of conformal anomalies in d=4 for the and of chiral anomalies for the is known in N-extended supergravities with . We propose…
More on DBI action in 4D supergravity
Shuntaro Aoki, Yusuke Yamada
We construct a Dirac-Born-Infeld (DBI) action coupled to a two-form field in four dimensional supergravity. Our superconformal formulation of the action shows a uni…
Multi-Loop Positivity of the Planar SYM Six-Point Amplitude
Lance J. Dixon, Matt von Hippel, Andrew J. McLeod +1
We study the six-point NMHV ratio function in planar SYM theory in the context of positive geometry. The Amplituhedron construction of the integrand for the amplitudes…
de Sitter Harmonies: Cosmological Spacetimes as Resonances
Jonathan Maltz
The aim of this work is to provided the details of a calculation summarized in the recent paper by Maltz and Susskind which conjectured a potentially rigorous framework where the s…
de Sitter as a Resonance
Jonathan Maltz, Leonard Susskind
A quantum mechanical formulation of de Sitter cosmological spacetimes still eludes string theory. In this paper we conjecture a potentially rigorous framework in which the status o…
Seven-Disk Manifold, alpha-attractors and B-modes
Sergio Ferrara, Renata Kallosh
Cosmological alpha-attractor models in \cN=1 supergravity are based on hyperbolic geometry of a Poincaré disk with the radius square {\cal R}^2=3α. The predictions for the B-modes,…
