SUMMARY:Color-kinematics duality in Yang-Mills theory from string amplitud
 es - Oliver Schlotterer (AEI)

CONTACT:Dr Dorigoni
DESCRIPTION:I will review the duality between color and kinematics in gaug
 e theories -- a striking resemblance between the color- and polarization- 
 or momenta dependent parts of Yang Mills (YM) amplitudes. As a key benefit
 \, it severely facilitates the construction of gravity amplitudes from gau
 ge theory. However\, manifestation of the duality requires a very particul
 ar arrangement of quartic vertices among cubic diagrams which could not ye
 t be systematized within the field theory setup. In this talk\, I will pro
 vide examples at tree level (based on 1104.5224) and at one-loop (work in 
 progress) how the field theory limit of superstring amplitudes naturally l
 eads to duality-satisfying representations of YM amplitudes.\n
