SUMMARY:Roberto Bonezzi: Worldlines\, gluons and (hopefully) color-kinemati
 cs duality - 
DESCRIPTION:Speaker: Roberto Bonezzi (HU Berlin)\n\nTitle: Worldlines\, gl
 uons and (hopefully) color-kinematics duality\n\nAbstract:\nThe double cop
 y construction of gravitational amplitudes relies on a hidden property of 
 gauge theories\, known as color-kinematics duality. Despite a lot of exper
 imental evidence and some partial proofs\, its origin remains somewhat mys
 terious. Recent progress in the double copy of Yang-Mills theory suggests 
 that gauge theories possess an off-shell hidden kinematic algebra\, which 
 ought to be responsible for the duality at the level of amplitudes. At the
  field theory level\, this hidden algebra is quite convoluted and hard to 
 describe. Inspired by string theory\, where the double copy was first disc
 overed\, I will present a worldline model which describes full Yang-Mills 
 theory at the perturbative level. I will show how the worldline carries th
 e gluon degrees of freedom\, and how its interactions are described by the
  insertion of vertex operators. This is a first step in view of deriving t
 he kinematic algebra from string-inspired techniques\, such as the OPE of 
 vertex operators.
