The paper “Scattering amplitude recursion relations in BV quantisable theories“, co-authored by Tommaso Macrelli, Christian Saemann (Heriot-Watt University), and Martin Wolf, has been published in Physical Review D.  Tree-level scattering amplitudes in Yang-Mills theory satisfy a recursion relation due to Berends and Giele which yields the famous Parke-Taylor formula for MHV amplitudes. The paper shows that the origin of this recursion relation becomes clear in the BV formalism, which encodes a field theory in an L-infinity algebra.
