We review the most recent results from experiments studying systems containing charmed quarks. The selection reflects the presenter’s bias, and there is an emphasis on decays of open charm. We discuss precision measurements of various sorts, various new states in the charmonium system, measurements aimed at testing Lattice QCD, and the latest searches for charm mixing. We conclude with a discus...

The spectrum of excitations of triply-charmed baryons is computed using lattice QCD including dynamical light quark fields. The spectrum obtained has baryonic states with well-defined total spin up to 7 2 and the low-lying states closely resemble the expectation from models with an SU(6)×O(3) symmetry. Energy splittings between extracted states, including those due to spin-orbit coupling in the...

Nucleon matrix elements of various four-quark operators are evaluated in quenched lattice QCD using Wilson fermions. Some of these operators give rise to twist-four contributions to nucleon structure functions. Furthermore, they bear valuable information about the diquark structure of the nucleon. Mixing with lower-dimensional operators is avoided by considering appropriate representations of t...

Results are presented on inclusive measurements of the spin structure function g 1 (x). The world's data on spin–dependent deep inelastic scattering are summarized. Results from recent Next–to–Leading Order (NLO) QCD analyses are given. They provide another successful test of QCD. The uncertainties arising from the low–x extrapolation of the inclusive data in absence of any measurement prevent ...

We review the calculation of moments of both the polarized and unpolarized parton distribution functions of the nucleon in lattice QCD, and in particular their extrapolation to the physical region. We also discuss the reconstruction of the x dependence of the valence quark distributions in the nucleon from a finite number of lattice moments.

We study Λ QCD /m B corrections to factorization in B → Kπ decays. First, we analyze these decay channels within factorization, showing that, irrespectively of the value of γ, it is not possible to reproduce the experimental data. Then, we discuss Λ QCD /m B corrections to these processes, and argue that there is a class of doubly Cabibbo enhanced non-factorizable contributions, usually called ...

I review recent Lattice results. In particular, the confinement mechanism and string breaking, glueballs and hybrid mesons as well as light hadron spectroscopy are discussed.

We test the quark mass dependence implemented in the quasiparticle dispersion relations of our quasiparticle model for the QCD equation of state by comparing with recently available lattice QCD data near Tc employing almost physical quark masses. In addition, we emphasize the capability of our model to successfully describe lattice QCD results for imaginary chemical potential and to analyticall...

The H-dibaryon, a J = 0 state with the valence quark content udsuds, has long been hypothesised to exist because of the attractive nature of colour magnetic gluon exchange in the flavoursinglet channel. Using lattice QCD the NPLQCD collaboration have investigated this system and evidence is presented for the existence of a stable H-dibaryon, albeit at a quark mass somewhat larger than that in n...

Parity and avor symmetry is not broken in QCD. Using this fact, we propose a new method to measure the chiral condensate in lattice QCD using Wilson fermions with an operator that breaks parity and avor in addition to the chiral symmetry.
