Descrição: dc.descriptionIn this paper, we consider the evaluation of the effective action for photons coupled to charged scalar fields in the framework of a ( 2 + 1 )-dimensional noncommutative spacetime. In order to determine the noncommutative Maxwell Lagrangian density, we follow a perturbative approach, by integrating out the charged scalar fields, to compute the respective graphs for the vev’s ⟨ A A ⟩ , ⟨ A A A ⟩ , and ⟨ A A A A ⟩ . Surprisingly, it is shown that these contributions are planar and that, in the highly noncommutative limit, correspond to the Maxwell effective action and its higher-derivative corrections. It is explicitly verified that the one-loop effective action is gauge invariant, as well as under discrete symmetries: parity, time reversal, and charge conjugation. Moreover, a comparison of the main results with the noncommutative QED 3 is established. In particular, the main difference is the absence of parity violating terms in the photon’s effective action coming from integrating out the charged scalar fields.-
