Analysis of e+e− → pp + (η, ω, η′, f1) at BESIII — •Marcel Rump, Johannes Bloms, Nils Hüsken, Johannes Kellers, Alfons Khoukaz, and Frederik Weidner — Westfälische Wilhelms-Universität Münster, Münster, Germany
Since the discovery of the χc1(3872) state by the BELLE experiment in 2003, a large number of new states were found in the mass region around 4 GeV/c2, which apparently do not fit into the scheme of conventional charmonium states. The possibility that some of these states could be of exotic nature has raised interest on charmonium physics to a new level. Using data collected with the Beijing Spectrometer III (BESIII) in positron-electron annihilations at the Beijing Electron-Positron Collider (BEPCII) above 4 GeV allows studying final states including a pp pair and different light mesons. Systematic searches for heavy resonances as well as their decays via nucleon resonances are performed analysing e+e− → pp + (η, ω, η′, f1). In this talk, the current status of the analysis will be discussed.
