The decays τ→ (η,η') K⁻ ντ in the extended Nambu-Jona-Lasinio model

الأصل · EN

The decays τ→ (η,η') K⁻ ντ are described in the framework of the extended Nambu-Jona-Lasinio model. Both full and differential widths of these decays are calculated. The vector and scalar channels are considered. In the vector channels, the subprocesses with intermediate K*(892) and K*(1410) mesons play the main role. In the scalar channels, the subprocesses with intermediate K₀*(800) and K₀*(1430) mesons are taken into account. Scalar channels play a less important role in calculation of the full width of the decay τ→ (η,η') K⁻ ντ. The obtained results are in satisfactory agreement with the experimental data.
