(Extended) Proca-Nuevo under the two-dimensional loupe

High Energy Physics - Theory 2022-12-07 v1

Abstract

Recently, two new families of non-linear massive electrodynamics have been proposed: Proca-Nuevo and Extended Proca-Nuevo. We explicitly show that both families are irremediably ghostful in two dimensions. Our calculations indicate the need to revisit the classical consistency of (Extended) Proca-Nuevo in higher dimensions before these settings can be regarded as ghostfree.
