“…To prepare experiments with PANDA, estimates for the production cross sections are required. They can be estimated by models relying on constant amplitude approximations and crossing symmetries requiring the a priori unknown ppπ 0 partial decay width of the states as an input parameter [2]. ppπ 0 decay widths for charmonium states below the open charm threshold have been reported by various experiments and are relatively well known [3].…”

“…In this paper, the Born cross section of e + e − → ppπ 0 in the vicinity of the ψ(3770) resonance is studied using data taken by the Beijing Spectrometer III (BESIII) experiment. The cross section of the decay ψ(3770) → ppπ 0 is measured taking into account the interference between the continuum and resonant production amplitudes and the cross section of pp → ψ(3770)π 0 , which is an estimate for open charm production in pp annihilations, for the kinematic situation at the PANDA experiment is evaluated using a model based on a constant amplitude approximation [2].…”

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.

A golden age for heavy quarkonium physics dawned a decade ago, initiated by the confluence of exciting advances in quantum chromodynamics (QCD) and an explosion of related experimental activity. The early years of this period were chronicled in the Quarkonium Working Group (QWG) CERN Yellow Report (YR) in 2004, which presented a comprehensive review of the status of the field at that time and provided specific recommendations for further progress. However, the broad spectrum of subsequent breakthroughs, surprises, and continuing puzzles could only be partially anticipated. Since the release of the YR, the BESII program concluded only to give birth to BESIII; the B-factories and CLEO-c flourished; quarkonium production and polarization measurements at HERA and the Tevatron matured; and heavy-ion collisions at RHIC have opened a window on the deconfinement regime. All these experiments leave legacies of quality, precision, and unsolved mysteries for quarkonium physics, and therefore beg for continuing investigations at BESIII, the LHC, RHIC, FAIR, the Super Flavor and/or Tau-Charm factories, JLab, the ILC, and beyond. The list of newly-found conventional states expanded to include hc(1P ), χc2(2P ), B + c , and η b (1S). In addition, the unexpected and still-fascinating X(3872) has been joined by * Editors † Section coordinators ‡ Corresponding author: bkh2@cornell.edu more than a dozen other charmonium-and bottomonium-like "XY Z" states that appear to lie outside the quark model. Many of these still need experimental confirmation. The plethora of new states unleashed a flood of theoretical investigations into new forms of matter such as quark-gluon hybrids, mesonic molecules, and tetraquarks. Measurements of the spectroscopy, decays, production, and in-medium behavior of cc, bb, and bc bound states have been shown to validate some theoretical approaches to QCD and highlight lack of quantitative success for others. Lattice QCD has grown from a tool with computational possibilities to an industrialstrength effort now dependent more on insight and innovation than pure computational power. New effective field theories for the description of quarkonium in different regimes have been developed and brought to a high degree of sophistication, thus enabling precise and solid theoretical predictions. Many expected decays and transitions have either been measured with precision or for the first time, but the confusing patterns of decays, both above and below open-flavor thresholds, endure and have deepened. The intriguing details of quarkonium suppression in heavy-ion collisions that have emerged from RHIC have elevated the importance of separating hotand cold-nuclear-matter effects in quark-gluon plasma studies. This review systematically addresses all these matters and concludes by prioritizing directions for ongoing and future efforts.

Decays of charmonia(-like) particles with definite JPC (e.g. χc1(3872)) to a $$ {D}^0{\overline{D}}^0 $$ D 0 D ¯ 0 system and any combination of C-definite decay particles, are sources of quantum-correlated $$ {D}^0{\overline{D}}^0 $$ D 0 D ¯ 0 systems with C = P = ±1. Several b-hadron decays also produce quantum-correlated $$ {D}^0{\overline{D}}^0 $$ D 0 D ¯ 0 systems. Advantages of isolating these systems in their C = +1 components for amplitude analyses and studies of lineshapes are discussed. Methods to separate the C = ±1 $$ {D}^0{\overline{D}}^0 $$ D 0 D ¯ 0 components from χc1(3872) decay samples are presented. Studies of T and CPT conservation in C = +1 $$ {D}^0{\overline{D}}^0 $$ D 0 D ¯ 0 systems can be performed with more easily reconstructible final states, when compared to C = −1 $$ {D}^0{\overline{D}}^0 $$ D 0 D ¯ 0 systems. Experimental mechanisms that can produce C = ±1 $$ {D}^0{\overline{D}}^0 $$ D 0 D ¯ 0 systems are described in an appendix.
