We investigate the structure of the Ds1(2460, 2536)(J P = 1+) mesons via analyzing the semileptonic Bc → Ds1ll, l = τ, μ, e and Bc → Ds1νν̄ transitions in the framework of the three–point QCD sum rules. We consider the Ds1 meson in two ways, the pure |cs̄〉 state and then as a mixture of two |P1〉 and |P1〉 states. Such type rare transitions take place at loop… CONTINUE READING
