摘要：In this work, we propose the N =2 and N =4 supersymmetric extensions of the Lorentz-breaking
Abelian Chern-Simons term. We formulate the question of the Lorentz violation in 6 and 10
dimensions to obtain the bosonic sectors of N = 2− and N = 4− supersymmetries, respectively.
From this, we carry out an analysis in N = 1− D = 4 superspace and, in terms of N = 1−
superfields, we are able to write down the N = 2 and N = 4 supersymmetric extensions of the
Lorentz-violating action term.
