Abstract: The calculation results of widths of the decays (Formula presented.), and (Formula presented.) and of the cross sections of the processes (Formula presented.) and (Formula presented.) carried out as part of the extended Nambu–Jona-Lasinio (NJL) model are presented. Due to the absence of the appropriate experimental values, the results should be considered predictions. A comparison of the calculated widths of these tau decays to the results of other authors is carried out.
