 ">On-shell Correlators and Color-Kinematics Duality in Curved Spacetimes</
 a>\nby Allic Sivaramakrishnan (Caltech) as part of Theoretical Physics Sem
 inars (Kentucky)\n\n\nAbstract\nIn this talk\, we present progress towards
  generalizing on-shell kinematics and color-kinematics duality to curved s
 pacetimes. First\, we define a perturbatively calculable quantity—the on
 -shell correlator—which furnishes a unified description of particle dyna
 mics in curved spacetime. Specializing to the cases of flat and anti-de Si
 tter space\, on-shell correlators coincide precisely with on-shell scatter
 ing amplitudes and boundary correlators respectively. We then introduce a 
 notion of on-shell kinematics for symmetric spaces in which the correspond
 ing on-shell momenta are built from isometry generators. Using this isomet
 ric language in AdS\, we compute scalar correlators and give a field-theor
 etic derivation of color-kinematics duality for the nonlinear sigma model.
  Finally\, we comment on possible extensions to spacetimes without symmetr
 y.\n\nZoom: https://uky.zoom.us/j/86707156638?pwd=VUNFUUl0cmxGMVArNXpVTTV1
