Published in 2020 at "Journal of High Energy Physics"

DOI: 10.1007/jhep06(2020)068

Abstract: 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 technical details that were left implicit previously.… read more here.

Published in 2021 at "Journal of High Energy Physics"

DOI: 10.1007/jhep09(2021)041

Abstract: Abstract In this paper we use the spinor-helicity formalism to calculate 3-point functions involving scalar operators and spin-s conserved currents in general 3d CFTs. In spinor-helicity variables we notice that the parity-even and the parity-odd… read more here.

Published in 2019 at "Physical Review D"

DOI: 10.1103/physrevd.100.045005

Abstract: We consider massless fields of arbitrary spin in de Sitter space. We introduce a spinor-helicity formalism, which encodes the field data on a cosmological horizon. These variables reduce the free S-matrix in an observer's causal… read more here.
