Homotopy Double Copy of Noncommutative Gauge Theories

  • Richard J. Szabo and
  • Guillaume Trojani

4 August 2023

We discuss the double-copy formulation of Moyal–Weyl-type noncommutative gauge theories from the homotopy algebraic perspective of factorisations of L∞-algebras. We define new noncommutative scalar field theories with rigid colour symmetr...
