Title: $Z_{c} (4100)$ and $Z_{c} (4200)$ as hadrocharmonium

Abstract

It is suggested that the recently reported charged charmoniumlike resonance Z_c(4100) and the previously observed Z_c(4200) are two states of hadrocharmonium, related by the charm quark spin symmetry in the same way as the lowest charmonium states η_c and J/ψ. Namely, the Z_c(4100) is (dominantly) the η_c embedded in a light-quark excitation with quantum numbers of a pion, while the Z_c(4200) is a similar four quark state containing J/ψ instead of η_c. It is argued that this picture suggests certain relations between the properties of the two exotic resonances and a distinctive pattern of their decays that can be tested experimentally. It is also pointed out that due to the presence of a spatially compact cc¯ charmonium the discussed exotic Z_c states may be produced as resonances in the s channel in p¯p annihilation.

We study η_c production at center-of-mass energies √s from 4.18 to 4.60 GeV in e⁺e^– annihilation data collected with the BESIII detector operating at the BEPCII storage ring, corresponding to 7.3 fb^–1 of integrated luminosity. We measure the cross sections of the three different exclusive reactions e⁺e^– → η_cπ⁺π^–π⁰, e⁺e^– → η_cπ⁺π^–, and e⁺e^– → η_cπ⁰γ. We find significant η_c production in e⁺e^– → η_cπ⁺π^–π⁰ at √s of 4.23 GeV and 4.26 GeV and observe a significant energy-dependent Born cross section that we measure to be consistent with the production via the intermediate Y(4260) resonance. In addition, we perform a search for a charmoniumlike Z_c state close to themore »« less

Radiative and pionic transitions $Z_{c} (4020)^{0} \to X (3872) γ$ and $Z_{c} (4020)^{\pm} \to X (3872) π^{\pm}$

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

The radiative transitions from the neutral exotic Z_c(4020)⁰ resonance to X(3872) with emission of a photon and the pionic transitions from the charged Z_c(4020)± to X(3872) and a charged pion π^± are considered for both charmoniumlike states being charmed meson-antimeson molecules. The underlying processes for these transitions are the decays of the charmed vector meson to pseudoscalar plus a photon or a pion. It is found that the discussed transition rates typically amount to a branching fraction of several permil with a peak at the vector meson pair threshold.

Measurements of the absolute branching fractions of $B^{+} \to X_{c \bar{c}} K^{+}$ and $B^{+} \to {\bar{D}}^{(*) 0} π^{+}$ at Belle

Journal Article Kato, Y. ; Iijima, T. ; Adachi, I. ; ... - Physical Review D

We present the measurement of the absolute branching fractions of B⁺ → X_cc¯K⁺ and B⁺ → D¯^(*)0π₊ decays, using a data sample of 772 × 10⁶ BB¯ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e⁺e^– collider. Here, X_cc¯ denotes η_c, J/ψ, χ_c0, χ_c1, η_c(2S), ψ(2S), ψ(3770), X(3872), and X(3915). We do not observe significant signals for X(3872) or X(3915) and set the 90% confidence level upper limits at B(B⁺ → X(3872)K⁺) < 2.6 × 10^–4and B(B⁺ → X(3915)K⁺) < 2.8 × 10^–4. These represent the most stringent upper limit for B(B⁺ → X(3872)K⁺)more »« less
