Decays $I ¨ \to f_{0} (I ¨ , K) I^½_{I ¨} $ and $I ¨ \to 3 I ¨ I^½_{I ¨} $ accounting for the contribution of $f_{0} (500)$

M. K. Volkov, A. A. Pivovarov, K. Nurlan

In the $U (3) \times U (3)$ quark NJL model, $I ¨ $ lepton decays with the production of scalar mesons $f_{0} (I ¨ , K])$ and neutrinos are studied, where $f_{0} = f_{0} (500), f_{0} (980)$ . It is sho…

Description of the processes $e^{+} e^{-} \to I ¨ ^{+} I ¨ ^{-}$ and $I ¨ ^{-} \to I ¨ ^{-} I ¨ ^{0} I^½_{I ¨} $ in the NJL model with value of the vector coupling constant $g_{I ¨} = 6$

M. K. Volkov, A. A. Pivovarov, K. Nurlan

It is shown that the processes $e^{+} e^{-} \to I ¨ ^{+} I ¨ ^{-}$ and $I ¨ ^{-} \to I ¨ ^{-} I ¨ ^{0} I^½_{I ¨} $ can be described in a unified approach in satisfactory agreement with experiment using the vec…

Description of the processes $e^{+} e^{-} \to K^{+} K^{-} I ¨ ^{0}$ and $e^{+} e^{-} \to K^{+} K^{-} I^\cdot$ within the extended NJL model

M. K. Volkov, A. A. Pivovarov, K. Nurlan

In the framework of the $U (3) \times U (3)$ extended Nambu-Jona-Lasinio model, the processes $e^{+} e^{-} \to K^{+} K^{-} I ¨ ^{0}$ and $e^{+} e^{-} \to K^{+} K^{-} I^\cdot$ are described taking into account both…
