The electromagnetic form factors of the spin-3/2 $\Omega$ baryons, namely $\Omega$, $\Omega_c^\ast$, $\Omega_{cc}^\ast$ and $\Omega_{ccc}$, are calculated in full QCD on $32^3\times 64$ PACS-CS lattices with a pion mass of 156(9) MeV. The…

The hadronic two-body weak decays of the doubly charmed baryons $\Xi_{cc}^{++}, \Xi_{cc}^+$ and $\Omega_{cc}^+$ are studied in this work. To estimate the nonfactorizable contributions, we work in the pole model for the $P$-wave amplitudes…

We report the first observation of two charmed strange baryons that decay into $\Lambda_c^+ K^-\pi^+$. The broader of the two states is measured to have a mass of $2978.5\pm 2.1\pm 2.0$ MeV/$c^2$ and a width of $43.5\pm 7.5\pm 7.0$…

We study the singly charmed baryon two-body decays of $\mathbf{B}_c \rightarrow \mathbf{B}_D P$ under $SU(3)_{F}$ flavor symmetry, where ${\bf B}_{c}$ refers to anti-triplet singly charmed baryons, and ${\bf B}_{D}$ and $P$ denote decuplet…

We evaluate exclusive semileptonic decays of ground-state spin-1/2 doubly heavy charmed baryons driven by a $c\to s,d$ transition at the quark level. Our results for the form factors are consistent with heavy quark spin symmetry constraints…
