Revisiting radiative transitions of charmonium states in covariant confined quark model
Aidos Issadykov, Mikhail A. Ivanov, Dang-Khoa N. Nguyen +3
We calculate the amplitudes and branching fractions of , , , and radiative decays in the framework of the covariant confined quark model. First, we explic…
Analyzing leptonic decays of heavy quarkonia in covariant confined quark model
Stanislav Dubnička, Anna Zuzana Dubničková, Mikhail A. Ivanov +3
The leptonic decay widths of heavy quarkonia are complementary observables to the semileptonic decays of heavy mesons and provide additional insight into the possible lepton flavor…
Weak nonleptonic decays of vector B-mesons
Mikhail A. Ivanov, Zhomart Tyulemissov, Akmaral Tyulemissova
We study the radiative and weak nonleptonic decays of vector B-mesons within the covariant confined quark model (CCQM) developed in our previous papers. First, we calculate the mat…
