[phys4phys] Group for Gravitation, Particles and Fields seminar, Friday, 24th of April, 2026

[prlina]

Dear colleagues,

You are cordially invited to the seminar of the Group for Gravitation, 
Particles and Fields, which will be held on Friday, 24th of April, 2026, 
at 11:00 at the Institute of Physics Belgrade, lecture hall 360.

The talk entitled:

Phenomenology of the Minimal Noncommutative Standard Model in the 
Process qq→ZZ→4l

will be given by Matej Maleš (Institute of Physics Belgrade).

Abstract: 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.
