Decays of τ → ρ(770)(ρ′(1450))ντ and τ → K∗(892)(K∗′(1410))ντ in the extended Nambu–Jona-Lasinio model

Abstract

In the extended Nambu–Jona-Lasinio model the decay widths [Formula: see text] and [Formula: see text] are studied in the quark one-loop approximation. Our estimations of the decay widths [Formula: see text] are in satisfactory agreement with experimental data. In the paper, the decay widths [Formula: see text] are also calculated.
