TL;DR: In this paper, the authors review the theory and present status of the proton spin problem with emphasis on the transition between current quarks and constituent quarks in QCD, and propose a solution to the problem.

TL;DR: A review of the experimental and theoretical progress in the field of charmed meson discovery can be found in this article, where two narrow charm-strange states $D{s0}^*(2317)$ and $D_{s1}(2460)$ were discovered by the BaBar and CLEO Collaborations, respectively.
Abstract: Since the discovery of the first charmed meson in 1976, many open-charm and open-bottom hadrons were observed. In 2003 two narrow charm-strange states $D_{s0}^*(2317)$ and $D_{s1}(2460)$ were discovered by the BaBar and CLEO Collaborations, respectively. After that, more excited heavy hadrons were reported. In this work, we review the experimental and theoretical progress in this field.

TL;DR: In this paper, the s-wave amplitudes of the SU(3) chiral meson-baryon Lagrangian with a coupled channel potential were identified in a Lippmann-Schwinger equation, and the strangeness S = −1 resonance Λ(1405) and the S 11(1535) nucleon resonance emerged as quasi-bound states of anti-kaon/nucleon and kaon/Σ-hyperon.
