Very recently, the LHCb collaboration has observed in the final state Λ _c^+ K^-π^+ π^+ Λ c+ K-π+ π+ a resonant structure that is identified as the doubly charmed baryon Ξ _ cc^++ Ξ …

We present a study of mass spectra and electromagnetic couplings of S-and P-wave baryons containing one, two or three heavy quarks, either charm (c) or bottom (b), in the …
We study charmed and strange baryon resonances that are generated dynamically by a unitary baryon-meson coupled-channel model which incorporates heavy-quark spin …

The constituent quark model is used to compute the ground and excited state masses of QQQbaryons containing either c or bquarks. The quark model parameters previously used to …
We extend the chromomagnetic model by further considering the effect of color interaction. The effective mass parameters between quark pairs (mqq or mqq¯) are introduced to …

The s-wave interaction of ̄D\Lambda_c, ̄D\Sigma_c, ̄D^∗\Lambda_c, ̄D^∗\Sigma_c and ̄D\Sigma_c^∗, ̄D^∗\Sigma_c^∗, is studied within a unitary coupled channels …
Until now, the first reported doubly charmed baryon Ξ cc+(3520) is still a puzzle. It was discovered and confirmed by SELEX collaboration, but not confirmed by LHCb, BABAR …

Approximate heavy-quark spin and flavor symmetry and chiral symmetry play an important role in our understanding of the nonperturbative regime of strong interactions. In this work …
We analyze weak decays of triply heavy baryon Ω cc c++ and calculate the form factors for Ω cc c++→ Ξ c c++/Ω c c+ transitions in a light front quark model. The momentum distributions …
