Title: Observation of χ_c1 Decays into Vector Meson Pairs ΦΦ, ωω and, ωΦ

Abstract

Using (106±4)×10⁶ ψ(3686) events accumulated with the BESIII detector at the BEPCII e⁺e⁻ collider, we present the first measurement of decays of χ_c1 to vector meson pairs ΦΦ, ωω, and ωΦ. The branching fractions are measured to be (4.4±0.3±0.5)×10⁻⁴, (6.0±0.3±0.7)×10⁻⁴, and (2.2±0.6±0.2)×10⁻⁵, for χ_c1 →ΦΦ, ωω, and ωΦ, respectively, which indicates that the hadron helicity selection rule is significantly violated in χ_cJ decays. In addition, the measurement of χ_cJ→ωΦ provides the first indication of the rate of doubly OZI-suppressed χ_cJ decay. Finally, we present improved measurements for the branching fractions of χ_c0 and χ_c2 to vector meson pairs.

  abstractNote = {Using (106±4)×10⁶ ψ(3686) events accumulated with the BESIII detector at the BEPCII e⁺e⁻ collider, we present the first measurement of decays of χc1 to vector meson pairs ΦΦ, ωω, and ωΦ. The branching fractions are measured to be (4.4±0.3±0.5)×10⁻⁴, (6.0±0.3±0.7)×10⁻⁴, and (2.2±0.6±0.2)×10⁻⁵, for χc1 →ΦΦ, ωω, and ωΦ, respectively, which indicates that the hadron helicity selection rule is significantly violated in χcJ decays. In addition, the measurement of χcJ→ωΦ provides the first indication of the rate of doubly OZI-suppressed χcJ decay. Finally, we present improved measurements for the branching fractions of χc0 and χc2 to vector meson pairs.},

Observation of {chi}{sub c1} Decays into Vector Meson Pairs {phi}{phi}, {omega}{omega}, and {omega}{phi}

Journal Article Ablikim, M ; An, Z H ; Bai, J Z ; ... - Physical Review Letters

Using (106{+-}4)x10{sup 6} {psi}(3686) events accumulated with the BESIII detector at the BEPCII e{sup +}e{sup -} collider, we present the first measurement of decays of {chi}{sub c1} to vector meson pairs {phi}{phi}, {omega}{omega}, and {omega}{phi}. The branching fractions are measured to be (4.4{+-}0.3{+-}0.5)x10{sup -4}, (6.0{+-}0.3{+-}0.7)x10{sup -4}, and (2.2{+-}0.6{+-}0.2)x10{sup -5}, for {chi}{sub c1}{yields}{phi}{phi}, {omega}{omega}, and {omega}{phi}, respectively, which indicates that the hadron helicity selection rule is significantly violated in {chi}{sub cJ} decays.

Observation of New Resonant Structures in $γ γ \to ω Φ$ , $Φ Φ$ , and $ω ω$

Journal Article Liu, Z. Q. ; Shen, C. P. ; Yuan, C. Z. ; ... - Physical Review Letters

The processes γγ --> ωΦ, ΦΦ, and ωω are measured using an 870 fb^-1 data sample collected with the Belle detector at the KEKB asymmetric-energy e⁺e^- collider. Production of vector meson pairs is clearly observed and their cross sections are measured for masses that range from threshold to 4.0 GeV. In addition to signals from well established spin-zero and spin-two charmonium states, there are resonant structures below charmonium threshold, which have not been previously observed. We report a spin-parity analysis for the new structures and determine the products of the η_c, χ_c0, and χ_c2 two-photon decay widths and branchingmore » fractions to ωΦ, ΦΦ, and ωω.« less

Improved measurements of two-photon widths of the $χ_{c J}$ states and helicity analysis for $χ_{c 2} \to γ γ$

Journal Article Ablikim, M. ; Achasov, M. N. ; Ahmed, S. ; ... - Physical Review D

Based on 448.1 x 10⁶ ψ(3686) events collected with the BESIII detector, the decays ψ(3686) → γχ_cJ,χ_cJ → γγ(J = 0,1,2) are studied in this paper. The decay branching fractions of χ_c0,2 → γγ are measured to be β(χ_c0 → γγ) = (1.93 ± 0.08 ± 0.05 ± 0.05) x 10^-4 and β(χ_c2 → γγ) = (3.10 ± 0.09 ± 0.07 ± 0.11) x 10^-4, which correspond to two-photon decay widths of Γ_γγ(χ_c0) = 2.03 ± 0.08 ± 0.06 ± 0.13 keV and Γ_γγ(χ_c2) = 0.60 ± 0.02 ± 0.01 ± 0.04 keV with a ratio of R = Γ_γγ(χ_c2)/Γ_γγ(χ_c0)more »« less

Study of electromagnetic Dalitz decays $χ_{c J} \to μ^{+} μ^{-} J / ψ$

Journal Article Ablikim, M. ; Achasov, M. N. ; Ahmed, S. ; ... - Physical Review D

Using 4.48 × 10⁸ ψ (3686) events collected with the BESIII detector, we search for the decays χ_cJ → μ⁺μ^– J/ψ through the radiative decays ψ(3686) → γχ_cJ, where J = 0,1,2. The decays χ_c1,2 → μ⁺μ^–J/ψ are observed, and the corresponding branching fractions are measured to be B(χ_c1 → μ⁺μ^–J/ψ) = (2.51 ± 0.18 ± 0.20) × 10^–4 and B(χ_c2 → μ⁺μ^–J/ψ) = (2.33 ± 0.18 ± 0.29) × 10^–4, where the first uncertainty is statistical and the second one systematic. No significant χ_c0 → μ⁺μ^–J/ψ decay is observed, and the upper limit on the branching fraction is determinedmore »« less
