“…In experiments, the higher order amplitudes for the transitions χ c1,2 (1P) → J/ψγ and/or ψ(2S ) → χ c1,2 (1P)γ have been measured in different experiments [110][111][112][113][114][115]. Our predictions with both the linear and screened potential models compared with the data have been listed in Tab.…”

Charmonium spectrum and electromagnetic transitions with higher multipole contributions

The charmonium spectrum is calculated with two nonrelativistic quark models, the linear potential model and the screened potential model. Using the obtained wavefunctions, we evaluate the electromagnetic transitions of charmonium states up to 4S multiplet. The higher multipole contributions are included by a multipole expansion of the electromagnetic interactions. Our results are in reasonable agreement with the measurements. As conventional charmonium states, the radiative decay properties of the newly observed charmonium-like states, such as X(3823), X(3872), X(4140/4274), are discussed. The X(3823) as ψ 2 (1D), its radiative decay properties well agree with the observations. From the radiative decay properties of X(3872), one can not exclude it as a χ c1 (2P) dominant state. We also give discussions of possibly observing the missing charmonium states in radiative transitions, which might provide some useful references to look for them in forthcoming experiments. The higher multipole contributions to the electromagnetic transitions are analyzed as well. It is found that the higher contribution from the magnetic part could give notable corrections to some E1 dominant processes by interfering with the E1 amplitudes. Our predictions for the normalized magnetic quadrupole amplitudes M 2 of the χ c1,2 (1P) → J/ψγ processes are in good agreement with the recent CLEO measurements.

“…This program of BESIII resulted so far in a variety of papers that can be found in Refs. [3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29]. The bulk of the activities below the open-charm threshold focuses on precision measurements of the properties of charmonium states, such as their masses, total widths, line shapes, and partial decay rates.…”

Despite the successes of the standard model, the non-perturbative dynamics of the strong interaction are not fully understood yet. Charmonium spectroscopy serves as an ideal tool to shed light on the dynamics of the strong interaction such as quark confinement and the generation of hadron masses. The BESIII collaboration studies extensively the strong interaction and various aspects that could shed light on physics beyond the standard model via copious e + e − collisions at the BESIII/BEPCII facility in Beijing, China, in the charmonium mass regime. I present a few of the recent results with the emphasis on charmonium spectroscopy and decay studies using 106×10 6 ψ(3686) events.International Winter Meeting on Nuclear Physics, 21-25 January 2013 Bormio, Italy * Speaker.

Towards larger distances, QCD becomes non-perturbative, and gives rise to spectacular phenomena such as the generation of hadron masses and quark confinement.
