Abstract: (Oxford Journals)
We study the P-wave charmed meson spectroscopy. We analyze the mixing of two 1^+ states, the masses and decay widths of the P-wave charmed mesons by use of the Breit-Fermi Hamiltonian to account for the 1/m_Q effects. Though the possibility of the case that D_1(2420) observed by experiments belongs to the s_l^P = (3/2)^+ dominant multiplet is high but not yet decisive. Therefore we also examine the case where the D_1(2420) belongs to the s_l^P = (1/2)^+ dominant multiplet. For these two cases the relation between the masses and decay widths of the P-wave charmed mesons is obtained. When D_1(2420) is assigned into the member of the s_l^P = (3/2)^+ dominant multiplet, the decay widths of unfound D_1 and D_0* become very large, which is consistent to the fact that these states are not found yet by the experiments.- charmed meson: hadron spectroscopy
