Double Copy of 3D Chern-Simons Theory and 6D Kodaira-Spencer Gravity
Roberto Bonezzi, Felipe Diaz-Jaramillo, Olaf Hohm
We apply an algebraic double copy construction of gravity from gauge theory to three-dimensional (3D) Chern-Simons theory. The kinematic algebra is the 3D de Rham comple…
Tree-level Scattering Amplitudes via Homotopy Transfer
Roberto Bonezzi, Christoph Chiaffrino, Felipe Diaz-Jaramillo +1
We formalize the computation of tree-level scattering amplitudes in terms of the homotopy transfer of homotopy algebras, illustrating it with scalar and Yang-Mills theory. Th…
Weakly Constrained Double Field Theory as the Double Copy of Yang-Mills Theory
Roberto Bonezzi, Christoph Chiaffrino, Felipe Diaz-Jaramillo +1
Weakly constrained double field theory, in the sense of Hull and Zwiebach, captures the subsector of string theory on toroidal backgrounds that includes gravity, -field and dila…
Old Dualities and New Anomalies
Roberto Bonezzi, Felipe Diaz-Jaramillo, Olaf Hohm
We revisit the question whether the worldsheet theory of a string admits a global O(d,d) symmetry. We consider the truncation of the target space theory in which fields are indepen…
