New baryons discovered by LHCb as the members of and states
Inspired by the newly observed states at LHCb, we decode their
properties by performing an analysis of mass spectrum and decay behavior. Our
studies show that the five narrow states, i.e., ,
, , , and
, could be grouped into the states with negative parity.
Among them, the and states could be the
candidates, while and are
suggested as the states. could be regarded as a
state. Since the the spin-parity, the electromagnetic transitions,
and the possible hadronic decay channels have not been
measured yet, other explanations are also probable for these narrow
states. Additionally, we discuss the possibility of the broad
structure as a state with or .
In our scheme, cannot be a candidate.Comment: 10 pages, 3 figures, 5 tables, typos corrected. Published in Phys.
