Impact of a Nonuniversal Z' on the B*>K&sup((* ))l*+l*- and B*>K&sup((* ))*n*n^- Processes / A.V.Bednyakov, A.I.Mukhaeva // Physical Review D [Electronic resource]. – 2023. – Vol.107, No.11. – P.115033. – URL: https://doi.org/10.1103/PhysRevD.107.115033. – Bibliogr.:62.
We perform a study of the new physics effects in semileptonic flavour changing neutral current (FCNC) processes within a low-energy approximation of the anomaly-free supersymmetic extension of the standard model (SM) with additional Z0 vector field. The key feature of the model is the nondiagonal structure of Z0 couplings to fermions, which is parametrized by few new-physics parameters in addition to well-known mixing matrices for quarks and leptons in the SM. We not only consider CP-conserving scenarios with real parameters, but also account for possible CP violation due to new physical weak phases. We analyze the dependence of the b → s observables on the parameters together with correlations between the observables predicted in the model. Special attention is paid to possible enhancement of B → Kð Þν¯ν rates and to CP-odd angular observables in B → K ll decays.
