Abstract

We present results of a 2+1+1 flavor twisted mass lattice QCD computation of the spectrum of D mesons and D_s mesons and of charmonium. Particular focus is put on the positive parity D states (so-called D^{∗ ∗} mesons) with quantum numbers J^P = 0⁺, 1⁺ and 2⁺. Besides computing their masses we are also separating and classifying the two J^P = 1⁺ states according to the angular momentum/spin of their light degrees of freedom (light quarks and gluons) j =1/2, 3/2.
