Investigation of the FCNC Processes in the 3-4-1-1 Model

We study the FCNC problems in 3-4-1-1 model a way different from previous work. The sources of at tree-level come both gauge and scalar sectors. show that most stringently bound on interactions comes meson oscillations. lower new physics scale is imposed more tightly than work, \(M_{new} > 22\) TeV. On allowed value domain physical scale, we contribution to BrB\(_s \rightarrow \mu^+ \mu^-)\) negligible.
