The masses of the tensor mesons are comparable to that of the charm quark mass $m_c$; therefore all terms including powers of $m_T/m_c$ are kept out in the expansion of the two-particle distribution amplitude $\\langle T|\\bar q_{1\\alpha}(x) \\, q_{2\\delta}(0)|0\\rangle$. Branching ratios of the semileptonic $D \\to T\\,\\mu \\,\\bar{\\nu}_{\\mu}$ decays and nonleptonic $D\\to T~ P ~(P=K, \\pi)$ decays are taken into consideration.
