Abstract: The values of the masses of the particles involved in the decay of Tcc+→D∗+D0→π+D0D0 suggest that due to the final state interactions in the transition vertex Tcc+→D∗+D0 there may be triangle logarithmic singularities. We discuss their possible role and show that the tree approximation for calculating the decay widths Tcc+→(D∗+D0+D∗0D+)→π+D0D0, π0D0D+, γD0D+ is quite sufficient at the current level of measurement accuracy.
