SUMMARY:Color-kinematics duality for QCD and pure gravities - Alexander Oc
 hirov (University of Edinburgh)

DESCRIPTION:Color-kinematics duality has been shown to be present in QCD s
 cattering  amplitudes with massive quarks. More generally\, the duality wa
 s extended  to gauge theories with flavored massive matter in any Lie-alge
 bra  representation\, with the resulting double copy for gravitational  am
 plitudes. In this talk\, I will discuss the details of the extension\,  in
 cluding a new decomposition of QCD amplitudes into independent  color-orde
 red primitives\, and how the duality imposes new relations  between the pr
 imitives. Furthermore\, I will discuss how the extension of  the duality c
 an be used to compute gravitational amplitudes with matter  and how this c
 an be used to obtain amplitudes in pure gravity theories.<br><br>Associate
