Abstract

We derive an explicit expression for the star product reproducing the κ\kappa-Minkowski Lie algebra in any dimension nn. The result is obtained by suitably reducing the Wick-Voros star product defined on Cθd\mathbb{C}^{d}_\theta with n=d+1n=d+1. It is thus shown that the new star product can be obtained from a Jordanian twist.
