Seminar of Hadron Physics

On 5 February 2016, at 11.00 am in Blokhintsev Hall (4 floor) a seminar “The decays τ → (η,η’) K- ντ in the extended Nambu-Jona-Lasinio model” will be held. Authors: M.K.Volkov and A.A.Pivovarov (BLTP, JINR).

Speaker: A.A.Pivovarov

Abstract:

The decays τ→(η,η′)K−νττ→(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)K∗(892) and K∗′(1410)K∗′(1410) mesons play the main role. In the scalar channels, the subprocesses with intermediate K0∗(800)K0∗(800) and K0∗′(1430)K0∗′(1430) mesons are considered. Scalar channels play a less important role in calculation of the full width of the ττ-decay. The results are in satisfactory agreement with the experimental data.
