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…
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…
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…
