Color-kinematics duality from an algebra of superforms
Roberto Bonezzi, Christoph Chiaffrino, Olaf Hohm +1
Color-kinematics duality states that the kinematic numerators of the cubic tree-level Yang-Mills scattering amplitudes obey the same symmetry properties that the color factors obey…
Yang-Mills kinematic algebra via homotopy transfer from a worldline operator algebra
Roberto Bonezzi, Christoph Chiaffrino, Olaf Hohm +1
The homotopy Lie or algebra encoding Yang-Mills theory is the tensor product of a color Lie algebra with the kinematic algebra. We derive this $C_{\infty}…
The Double Copy of Maximal Supersymmetry in
Roberto Bonezzi, Giuseppe Casale, Olaf Hohm
We continue the program of using homotopy algebras to obtain off-shell, local and gauge redundant derivations of the double copy relations between gauge theory and gravity. We appl…
Gluon amplitudes in first quantization
Fiorenzo Bastianelli, Roberto Bonezzi, Olindo Corradini +1
We compute tree-level gluon amplitudes as worldline correlators of vertex operators in a bosonic spinning particle model. In this framework, the particle's position degrees of free…
Worldline geometries for scattering amplitudes
Roberto Bonezzi, Maria Foteini Kallimani
In this paper, we construct the path integral for infinite and semi-infinite scalar worldlines. We show that, at the asymptotic endpoints, on-shell physical states can be generated…
The Double Copy of Maximal Supersymmetry in
Roberto Bonezzi, Giuseppe Casale, Olaf Hohm
We realize off-shell, local and gauge invariant supergravity in , to cubic order in fields, as the double copy of super Yang-Mills theory (SYM). Employing the homo…
