Spinor-Helicity Formalism for Massless Fields in AdS III: Contact Four-Point Amplitudes
Balakrishnan Nagaraj, Dmitry Ponomarev
We study contact four-point amplitudes in the spinor-helicity formalism in anti-de Sitter space. We find that these amplitudes can be brought to an especially simple form, which we…
Spinor-Helicity Formalism for Massless Fields in AdS II: Potentials
Balakrishnan Nagaraj, Dmitry Ponomarev
In a recent letter we suggested a natural generalization of the flat-space spinor-helicity formalism in four dimensions to anti-de Sitter space. In the present paper we give some t…
From Minkowski to de Sitter in Multifield No-Scale Models
John Ellis, Balakrishnan Nagaraj, Dimitri V. Nanopoulos +2
We show the uniqueness of superpotentials leading to Minkowski vacua of single-field no-scale supergravity models, and the construction of dS/AdS solutions using pairs of these sin…
Spinor-Helicity Formalism for Massless Fields in AdS
Balakrishnan Nagaraj, Dmitry Ponomarev
In this letter we suggest a natural spinor-helicity formalism for massless fields in AdS. It is based on the standard realization of the AdS isometry algebra …
De Sitter Vacua in No-Scale Supergravity
John Ellis, Balakrishnan Nagaraj, Dimitri V. Nanopoulos +1
No-scale supergravity is the appropriate general framework for low-energy effective field theories derived from string theory. The simplest no-scale Kähler potential with a single…
Correlators of Mixed Symmetry Operators in Defect CFTs
Sunny Guha, Balakrishnan Nagaraj
We use the embedding formalism to study correlation functions of a d-dimensional Euclidean CFT in the presence of a co-dimensional defect. The defect breaks the global conforma…
