This enabl es a classical double-copy construction that generates corresponding class ical solutions in string gravity (axion-dilaton gravity). While the origin al double copy of scattering amplitudes traces back to results in perturba tive string theories\, we find that classical open and closed strings are possible “UV completions” to these worldline effective field theories of the sources by comparing to the low energy radiation from these rotatin g strings. Moreover\, we show that the higher dimensional operators encodi ng tidal deformation can also be added to this construction\, provided tha t the Wilson coefficients of the dilatonic and axionic operators are fixed with respect to the gravitational ones.\n LOCATION:https://researchseminars.org/talk/CMU-TP/20/ END:VEVENT END:VCALENDAR
