Title: Some decay properties of hidden-charm pentaquarks as baryon-meson molecules

Abstract

It is pointed out that the previously suggested interpretation of the hidden-charm pentaquarks P_c(4312), P_c(4440), and P_c(4457) as molecular bound states of Σ_cD¯ and Σ_cD¯* baryon-meson pairs gives rise to specific relations for their decays. In particular, the heavy-quark spin symmetry predicts ratios of rates of decays of each of the molecules to J/ψp and to η_cp as well as of the decays to Λ_cD¯ and to Λ_cD¯*. Experimental studies of these relations would thus provide an indicative probe of the molecular structure.

Hidden-charm pentaquark formation in antiproton-deuterium collisions

Journal Article Voloshin, M. B. - Physical Review D

The possibility of observing formation of hidden-charm pentaquarks as s-channel resonances in antiproton-deuteron collisions is discussed. It is pointed out that the masses of the reported by LHCb pentaquark resonances in the J/ψp channel are very close to a special value of the mass at which formation of a pentaquark by antiproton incident on a deuteron at rest requires exactly the same momentum of the p¯ as needed for the formation in the s channel of the charmonium resonance in p¯p collisions with the proton being at rest. For this reason the former process can be rather completely described withinmore »« less

Production of $P_{c}$ states in $Λ_{b}$ decays

Journal Article Burns, T. J. ; Swanson, E. S. - Physical Review D

We develop a model for the production of the P_c states observed at LHCb in Λ_b → J/ψpK^– decays. With fewer parameters than other approaches, we obtain excellent fits to the J/ψp invariant mass spectrum, capturing both the prominent peaks, and broader features over the full range of invariant mass. A distinguishing feature of our model is that whereas P_c(4312), P_c(4380) and P_c(4440) are resonances withmore »« less

Formation of hidden-charm pentaquarks in photon-nucleon collisions

Journal Article Kubarovsky, Valery P. ; Voloshin, M. B. - Physical Review. D, Particles, Fields, Gravitation and Cosmology

The cross section for formation in γ + ρ collisions of the recently found hidden-charm pentaquark states Ρ_c(4380) and Ρ_c(4450) is discussed and estimated. The studies of these resonances in photon beam experiments can be complementary to those in the LHCb experiment setting, and may be more advantageous for measurement of their additional decay channels. It is pointed out that both the relative importance of such decays and the yield of the resonances in the γ + ρ collisions are sensitive to the internal dynamics of the pentaquarks and can resolve between theoretical models. Specific numerical estimates are discussed withinmore »« less

Study of B-Meson Decays to Final States with a Single Charm Baryon

Thesis/Dissertation Majewski, Stephanie A.

A study of B-meson decays to final states with a single charm baryon is presented based on data recorded by the BABAR detector at the Stanford Linear Accelerator Center. Although the B meson is the lightest bottom-flavored meson, it is heavy enough to decay to a baryon made of three quarks and an antibaryon made of three antiquarks. By studying the baryonic weak decays of the B meson, we can investigate baryon production mechanisms in heavy meson decays. In particular, we measure the rates of the decays B^- → Λ⁺_cmore »« less
