Phenomenology of the Minimal Noncommutative Standard Model in the Process qq→ZZ→4l
САЖЕТАК:
In this presentation we consider the process qq→ZZ, within the framework of the noncommutative Standard Model. After a brief motivation and a review of the basic characteristics of the Standard Model, we introduce the noncommutative star product. We follow the basic consequences of the Moyal–Weyl product and the Seiberg–Witten mappings on the form of the action, after which we restrict ourselves exclusively to the framework of the minimal noncommutative Standard Model. In the given model we examine from which parts of the action new terms relevant to our process are obtained. We focus on the newly arising vertex corrections, contact contributions, and contributions of the ZZZ vertex, where we go through the main differences in the calculation of Feynman amplitudes compared to the uncorrected Standard Model. We present the results of the calculation, and discuss potential further steps.
