TL;DR: In this paper, the generalized Cabibbo mixing angle connecting two types of quarks is predicted to be given order of magnitude wise by the square root of the corresponding quark mass ratio.

TL;DR: In this paper, the consequences of an effective lagrangian for quarks, gluons and goldstone bosons in the region between the chiral symmetry breaking and confinement scales were studied.

TL;DR: In this article, a gauge-invariant decomposition of the nucleon spin into quark helicity, quark orbital, and gluon contributions is proposed, and the total quark contribution is measured through virtual Compton scattering in a special kinematic region where single quark scattering dominates.
Abstract: I introduce a gauge-invariant decomposition of the nucleon spin into quark helicity, quark orbital, and gluon contributions. The total quark (and hence the quark orbital) contribution is shown to be measurable through virtual Compton scattering in a special kinematic region where single quark scattering dominates. This deeply virtual Compton scattering has much potential to unravel the quark and gluon structure of the nucleon.

TL;DR: In this paper, the authors consider propagation of heavy quarks in QCD matter and show that the radiative quark energy loss appears to be qualitatively different from that of light quarks at all energies of practical importance.

TL;DR: In this paper, it was shown that at some temperature quark releasing occurs due to string condensation, and the properties of the arising phase were investigated, and it was also shown that quark release occurs at certain temperature.
