BV quantization of braided scalar field theory

Abstract: We address the problem of UV/IR mixing in noncommutative quantum field theories from the perspective of braided $L_\infty$-structures and the Batalin-Vilkovisky formalism. We describe the example of braided noncommutative scalar field theory and its quantization using braided homological perturbation theory. The formalism is illustrated through one-loop calculations of the two-point functions for $\phi^4$-theory in four dimensions and $\phi^3$-theory in six dimensions. In both cases we find that there are no non-planar diagrams and no UV/IR mixing.
