The double copy: from BRST ghosts to classical fields
  OKC/Nordita High-Energy Physics Theory seminar

Monday 05 March 2018
from 13:15 to 14:15
at Nordita East Building ( 132:028 )
Speaker : Silvia Nagy (University of Nottingham)
Abstract : We present a procedure for perturbatively constructing the field content of gravitational theories from a convolutive product of two Yang-Mills theories. A dictionary "gravity=YM X YM" is developed, reproducing the symmetries and dynamics of the gravity theory from those of the YM theories. We explain the unexpected, yet crucial role played by the BRST ghosts of the YM system in the construction of gravitational fields. The dictionary is expected to develop into a solution-generating technique for gravity.
