The Double Copy & Lie polynomials

By Hadleigh Frost

The 'field theory KLT' or 'double copy' relations express gravity amplitudes in terms of gauge theory partial amplitudes. I present an elementary proof of these identities, using only the properties of Lie polynomials and the shuffle algebra. The work completes a project sketched by M Kapranov in 2012, and is joint with C Mafra.
