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

I review lattice QCD calculations that compute the masses of the flavour singlet pseudoscalar mesons. I describe the progress in computing the mass spectrum of light 0 ++ mesons using lattice QCD. I also compare the results for basic quantities such as f π and m ρ , from various different formalisms of lattice QCD. I discuss the physical value of r 0 .

We present some early results from a high statistics study of the scalar and pseudoscalar singlet sectors of lattice QCD using 2 + 1 flavours of Asqtad improved staggered fermions. The use of the Asqtad action has allowed us to generate an unprecedented number of configurations at 2 lattice spacings which on completion we hope will give us a significantly improved view of both the scalar and ps...

It is a long discussed issue whether light scalar mesons have sizeable four-quark components. We present an exploratory study of this question using N f = 2+ 1+ 1 twisted mass lattice QCD. A mixed action approach ignoring disconnected contributions is used to calculate correlator matrices consisting of mesonic molecule, diquark-antidiquark and two-meson interpolating operators with quantum numb...

Accurately calculating the mass of flavor-singlet meson states from numerical lattice simulations is an important milestone for lattice QCD. Careful measurement of the full pseudoscalar flavorsinglet propagator is also a crucial step in understanding the dynamics of the fermion sea on the lattice, in particular for potentially non-trivial formulations such as with 2+1-flavor staggered fermions....
