摘      要：We study the duality between color and kinematics for the Sudakov form factors of tr(F~2)in non-supersymmetric pure Yang-Mills *** construct the integrands that manifest the color-kinematics duality up to two *** resulting numerators are given in terms of Lorentz products of momenta and polarization vectors,which have the same powers of loop momenta as that from the Feynman *** integrands are checked by d-dimensional unitarity cuts and are valid in any *** find that massless-bubble and tadpole topologies are needed at two loops to realize the color-kinematics ***,the two-loop solution contains a large number of free parameters suggesting the duality may hold at higher loop orders.
