TL;DR: In this paper, the authors measured the branching ratio of the Cabibbo-favored decays Ξ c + → Σ + K − π +, and set 90% confidence level upper limits for the branching ratios with respect to Ξc + →Ξ− π−π + π+ π −π + to be 0.16±0.06, and 0.28± 0.12, respectively, and determined the 90% C.L.

Abstract: This report summarizes progress during the past year in the following areas of research: Pion double charge exchange, including studies of the contribution of meson exchange currents and the roles of chiral symmetry and of vector mesons. The possibility of bound states of two hyperons and the H dibaryon. Many body theory, including studies of nuclear scattering in a quark cluster model, nuclear structure calculations, and a one-dimensional model with charged'' bosons. Statistical nuclear spectroscopy, including formalism and programs for state densities and partition functions, single-state occupancies and spin-cut off factors, measures for symmetry breaking, and the relationship between statistical and shell-model spectroscopy.

TL;DR: Cheng et al. as discussed by the authors presented a review of charmed baryon physics, including spectroscopy, strong decays, lifetimes, non-leptonic and semileptonic weak decays and electromagnetic decays.
Abstract: This is essentially an update of Ref. [1] [H. Y. Cheng, Int. J. Mod. Phys. A 24 (Suppl. 1), 593 (2009)], a review of charmed baryon physics around 2007. Topics covered in this review include the spectroscopy, strong decays, lifetimes, nonleptonic and semileptonic weak decays, and electromagnetic decays of charmed baryons.

TL;DR: In this article, the authors evaluated the long-distance contributions of two-body intermediate states to the D 0 - ¯ D 0 mixing parameters x and y using latest data on hadronic D 0 decays and found that y is of order a few � 10 − 3 and x of order 10 −3 from hadronic PP and V P modes.
Abstract: Long-distance contributions to the D 0 - ¯ D 0 mixing parameters x and y are evaluated using latest data on hadronic D 0 decays. In particular, we take on two-body D ! PP and V P decays to evaluate the contributions of two-body intermediate states because they account for � 50% of hadronic D 0 decays. Use of the diagrammatic approach has been made to estimate yet-observed decay modes. We find that y is of order a few � 10 −3 and x of order 10 −3 from hadronic PP and V P modes. These are in good agreement with the latest direct measurement of D 0 - ¯ D 0 mixing parameters using the D 0 ! KS� + � − and KSK + K − decays by BaBar. We estimate the contribution to y from the V V modes using the factorization model and comment on the single-particle resonance effects and contributions from other two-body modes involving even-parity states.

TL;DR: Cheng et al. as mentioned in this paper reviewed the experimental progress and theoretical development of charmed baryon physics since 2007 and 2015, respectively, focusing on the theoretical development since 2015.
Abstract: This is an update of the two articles [H.Y. Cheng, Int. J. Mod. Phys. A {\bf 24} (Suppl. 1), 593 (2009); Front. Phys. {\bf 10}, 101406 (2015)] in which charmed baryon physics around 2007 and 2015, respectively, were reviewed. In this review we emphasize the experimental progress and the theoretical development since 2015.
