Prediction of five-flavored pentaquarks

We analyze the possibility of the existence of a fully exotic pentaquark state udscb, which is made from the five different flavors participating in the strong interactions. We investigate the coupled channel effects of the B-(*())Xi(('))(c) system through t-channel vector meson exchange to search for such states. A B Xi(c) and a B Xi(c)', bound state are found to have binding energies of about 10 - 30 MeV with B-s Lambda(c) and B-c Lambda being the possible decay channels. Similarly, a bound state is formed in the B*Xi(c) and B*Xi(')(c) channels, respectively. The properties of these states including pole positions, decay widths and couplings to other channels are extracted. These states could be searched for through the pp -> B-c Lambda X or pp -> B-s(()*()) Lambda X-c processes by the LHCb collaboration. (C) 2022 The Author(s). Published by Elsevier B.V.
