Investigation of the strange pentaquark candidate P?s ? (4338)0 recently observed by LHCb
No full textThe recently observed strange pentaquark candidate, P?s?(4338)0, is investigated to provide information about its nature and substructure. To this end, its mass and width through the decay channels P?s?(4338)0?J/?? and P?s?(4338)0??c? are calculated by applying two- and three-point QCD sum rules, respectively. The state is considered as a ?cD¯ meson-baryon molecular structure with spin-parity quantum numbers JP=12-. The obtained mass, mP?s?(4338)0=4338±130 MeV, and width, ?P?s?(4338)0=10.40±1.93 MeV, are consistent with the experimental data within the presented uncertainties. This allows us to assign a ?cD¯ molecular structure of JP=12- for the P?s?(4338)0 state. © 2023 authors. Published by the American Physical Society.

Production of from decay
Get PDFIn the present work, we investigate the production of the newly observed
state in decay, where the is assigned as a molecular state. By using an
effective Lagrangian approach, we evaluate the branching fractions of
via the triangle loop
mechanism. The branching fractions of are in the order of ; the result is compared with our
previous work of . We also
predict the ratio of and
productions in the decay . The predicted branching fractions and their ratios could be tested
experimentally, which may be helpful for understanding the molecular picture of
as well as other hidden-charm pentaquark states with
strangeness. Moreover, the experimental potential of observing in the is discussed.Comment: 7 pages, 5 figure

The LHCb state as a triangle singularity
No full textWe present a model for the J/ψΛ spectrum in B−→J/ψΛp¯ decays, including the PψsΛ(4338) baryon recently observed by the LHCb collaboration. We assume production via triangle diagrams which couple to the final state via non-perturbative interactions which are constrained by heavy-quark and SU3-flavor symmetry. The bulk of the distribution is described by a triangle diagram with a color-favored electroweak vertex, while the sharp PψsΛ(4338) enhancement is due to the triangle singularity in another diagram featuring a 1/2− baryon consistent with Σc(2800). We predict a comparable PψsΛ(4338) signal in ηcΛ, and anticipate possible large isospin mixing effects through decays to J/ψΣ0 and ηcΣ0.We present a model for the spectrum in decays, including the baryon recently observed by the LHCb collaboration.
