A topological quantum field theory for -instantons
Rafael Herrera, Sergio A. Holguin Cardona, Alexander Quintero Velez
We construct a topological quantum field theory based on the moduli space of -instantons on 8-dimensional manifolds. Using the Mathai-Quillen formalism, we derive…

Tree- and one-loop-level double copy for the (anti)self-dual sectors of Yang-Mills and gravity
Daniel Herrera Correa, Cristhiam Lopez-Arcos, Alexander Quintero Velez
By employing the perturbiner method we study the tree- and one-loop-level amplitudes in (anti)self-dual Yang-Mills, focusing on color-kinematics duality and double copy features; t…
