Abstract: The Ξ_{b}^{-}π^{+}π^{-} invariant mass spectrum is investigated with an event sample of proton-proton collisions at sqrt[s]=13 TeV, collected by the CMS experiment at the LHC in 2016-2018 and corresponding to an integrated luminosity of 140 fb^{-1}. The… read more here.

Abstract: We present the study of B[over ¯]^{0}→Σ_{c}(2455)^{0,++}π^{±}p[over ¯] decays based on 772×10^{6} BB[over ¯] events collected with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider. The Σ_{c}(2455)^{0,++} candidates are reconstructed via their decay to Λ_{c}^{+}π^{∓}… read more here.

DOI: 10.1142/s0217732319503449
Abstract: We calculate the mass and residue of the newly observed [Formula: see text] and [Formula: see text] states with quantum numbers [Formula: see text] and [Formula: see text] within QCD sum rules. The calculation is… read more here.
