Efficient calculation of crossing symmetric BCJ tree numerators

Efficient calculation of crossing symmetric BCJ tree numerators

Abstract In this paper, we develop an improved method for directly calculating double-copy-compatible tree numerators in (super-)Yang-Mills and Yang-Mills-scalar theories. Our new scheme gets rid of any explicit dependence on reference orderings, restoring a form of crossing symmetry to the numerato...
