“…The sum of those channels, however, is far from clarifying the mysterious situation of the ψ(3770) non-DD decays. It hence stimulates intensive experimental and theoretical efforts [16][17][18][19][20][21][22][23][24][25][26] on understanding the nature of ψ(3770) and its strong and radiative transition mechanisms.…”

We provide details of the study of ψ(3770) non-DD decays into V P , where V and P denote light vector meson and pseudoscalar meson, respectively. We find that the electromagnetic (EM) interaction plays little role in these processes, while the strong interaction dominates. The strong interaction can be separated into two parts, i.e. the short-distance part probing the wave function at origin and the long-distance part reflecting the soft gluon exchanged dynamics. The long-distance part is thus described by the intermediate charmed meson loops. We show that the transition of ψ(3770) → V P can be related to ψ(3686) → V P such that the parameters in our model can be constrained by comparing the different parts in ψ(3770) → V P to those in ψ(3686) → V P . Our quantitative results confirm the findings of [Zhang et al., Phys. Rev. Lett. 102, 172001 (2009)] that the OZI-rule-evading long-distance strong interaction via the IML plays an important role in ψ(3770) decays, and could be a key towards a full understanding of the mysterious ψ(3770) non-DD decay mechanism.

“…The ratio of the different isospin components of the virtual photon is for example discussed in [25,26]. The basic idea is the dominance of single states in the virtual intermediate state, which can be for example (excited) ρ * or ω * mesons or coherent pion configurations with I = 0 and I = 1, resulting in a ratio of (I=0) : (I=1) = 1 : 9.…”

Study of e + e − → ppπ 0 in the Vicinity of the ψ(3770) The process e + e − → ppπ 0 has been studied by analyzing data collected at √ s = 3.773 GeV, at √ s = 3.650 GeV, and during a ψ(3770) line shape scan with the BESIII detector at the BEPCII 3 collider. The Born cross section of ppπ 0 in the vicinity of the ψ(3770) is measured and the Born cross section of ψ(3770) → ppπ 0 is extracted considering interference between resonant and continuum production amplitudes. Two solutions with the same probability and a significance of 1.5σ are found. The solutions for the Born cross section of ψ(3770) → ppπ 0 are 33.8 ± 1.8 ± 2.1 pb and 0.06 +0.10+0.01 −0.04−0.01 pb (< 0.22 pb at a 90% confidence level). Using the estimated cross section and a constant decay amplitude approximation, the cross section σ(pp → ψ(3770)π 0 ) is calculated for the kinematic situation of the planned PANDA experiment. The maximum cross section corresponding to the two solutions is expected to be less than 0.79 nb at 90% confidence level and 122 ± 10 nb at a center of mass energy of 5.26 GeV.

Abstract. Some recent discoveries in the spectroscopy of hadrons containing heavy quarks, and some of their theoretical interpretations, are reviewed. IntroductionThe spectroscopy of states containing heavy quarks Q has undergone a great renaissance in recent years, providing an exceptional window into tests of QCD. Quarkonium systems QQ are amenable to perturbative descriptions of their decays. One can study Qq and Qqq hadrons (q = light quark u, d, s) in which the heavy quarks play the role of "nuclei," expanding observables in inverse powers of m Q . Many heavy-quark hadrons have masses and couplings strongly affected by nearby thresholds, as has been known for many years in the physics of atoms and nuclei [1,2,3]. Hadron spectra often are crucial in separating electroweak physics from strong-interaction effects. More broadly, QCD may not be the only instance of important nonperturbative effects. Understanding how such effects are manifested in hadrons may help prepare us for surprises at the CERN Large Hadron Collider (LHC). Finally, at the quark and lepton level there exists an intricate level structure and a set of transitions calling for fundamental understanding; spectroscopic methods may help.We begin this brief review by outlining some theoretical spectroscopic methods. We then discuss charmed and beauty hadrons, heavy quarkonium (cc, bb), and future prospects.
