Celestial amplitudes in an ambidextrous basis by Carmen Jorge-Diaz, Sabrina Pasterski, Atul Sharma

“…Finally, we focus on the tree level 4-gluon amplitude where we present a streamlined route to the ambidextrous correlator based on Grassmannian formulae and examine its alpha space representation. …”

Ambidextrous light transforms for celestial amplitudes by Atul Sharma

“…We also study such amplitudes at higher multiplicity by constructing the Grassmannian representation of tree-level gluon celestial amplitudes as well as their light transforms. …”
