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

Two-photon width of the charmonium state {chi}{sub c2}

Journal Article Dobbs, S ; Metreveli, Z ; Seth, K K ; ... - Physical Review. D, Particles Fields

The two-photon width of {chi}{sub c2}({sup 3}P{sub 2}) state of charmonium has been measured using 14.4 fb{sup -1} of e{sup +}e{sup -} data taken at {radical}(s)=9.46-11.30 GeV with the CLEO III detector. The {gamma}{gamma}-fusion reaction studied is e{sup +}e{sup -}{yields}e{sup +}e{sup -}{gamma}{gamma}, {gamma}{gamma}{yields}{chi}{sub c2}{yields}{gamma}J/{psi}{yields}{gamma}e{sup +}e{sup -}({mu}{sup +}{mu}{sup -}). We measure {gamma}{sub {gamma}}{sub {gamma}}({chi}{sub c2})B({chi}{sub c2}{yields}{gamma}J/{psi})B(J/{psi}{yields}e= {sup +}e{sup -}+{mu}{sup +}{mu}{sup -})=13.2{+-}1.4(stat){+-}1.1(syst) eV, and obtain {gamma}{sub {gamma}}{sub {gamma}}({chi}{sub c2})=559{+-}57(stat){+-}48(syst){+-}36(br) eV. This result is in excellent agreement with the result of {gamma}{gamma}-fusion measurement by Belle and is consistent with that of the pp{yields}{chi}{sub c2}{yields}{gamma}{gamma} measurement, when they are both reevaluated using the recentmore »« less

Effective Lagrangian for two-photon and two-gluon decays of P-wave heavy quarkonium {chi}{sub c0,2} and {chi}{sub b0,2} states

Journal Article Lansberg, J P ; Pham, T N - Physical Review. D, Particles Fields

In the traditional nonrelativistic bound state calculation, the two-photon decay amplitudes of the P-wave {chi}{sub c0,2} and {chi}{sub b0,2} states depend on the derivative of the wave function at the origin, which can only be obtained from potential models. However, by neglecting the relative quark momenta, the decay amplitude can be written as the matrix element of a local heavy quark field operator which could be obtained from other processes or computed with the QCD sum rules technique or lattice simulation. Following the same lines as in recent work for the two-photon decays of the S-wave {eta}{sub c} and {eta}{submore »« less

Experimental Investigation of the Two-Photon Widths of the {chi}{sub c0} and the {chi}{sub c2} Mesons

Journal Article Eisenstein, B I ; Ernst, J ; Gladding, G E ; ... - Physical Review Letters

Using 12.7 fb{sup -1} of data collected with the CLEO detector at CESR, we observed two-photon production of the c{bar c} states {chi}{sub c0} and {chi}{sub c2} in their decay to {pi}{sup +}{pi}{sup -}{pi}{sup +}{pi}{sup -} . We measured {Gamma}{sub {gamma}{gamma}}({chi}{sub c}) x B({chi}{sub c}{yields}{pi}{sup +}{pi}{sup -}{pi}{sup +}{pi}{sup - }) to be 75{+-}13(stat){+-}8(syst) eV for the {chi}{sub c0} and 6.4{+-}1.8(stat){+-}0.8( syst) eV for the {chi}{sub c2} , implying {Gamma}{sub {gamma}{gamma}}({chi}{sub c0})=3.76{+-}0.65(stat){+-} 0.41(syst){+-}1.69(br) keV and {Gamma}{sub {gamma}{gamma}}({chi}{sub c2})=0.53{+-}0.15(stat){+-} 0.06(syst){+-}0.22(br) keV . Also, cancellation of dominant experimental and theoretical uncertainties permits a precise comparison of {Gamma}{sub {gamma}{gamma}}({chi}{sub c0})/{Gamma}{sub {gamma}{gamma}}({chi}{sub c2}) , evaluatedmore »« less

Two-photon helicity selection rules and widths for positronium and quarkonium states with arbitrary angular momenta

Journal Article Ackleh, E S ; Barnes, T ; Close, F E - Physical Review, D (Particles Fields); (United States)

The observation of a large {gamma}{gamma} width for the {sup 1}{ital D}{sub 2} {ital q{bar q}} state {pi}{sub 2}(1670) suggests that the {gamma}{gamma} couplings of many orbitally excited light-quark {ital q{bar q}} states may be experimentally accessible. In this paper we present {gamma}{gamma} helicity amplitudes for nonrelativistic fermion-antifermion states with general angular-momentum quantum numbers {sup 1}{ital l}{sub {ital j}} and {sup 3}{ital l}{sub {ital j}}, and note some relations and selection rules that may be useful in the spectroscopic classification of orbital excitations.
