Recent highlights from BESIII: XYZ states
نویسنده
چکیده
In this contribution we review recent results from the BESIII experiment. We focus on the investigation of XYZ states and the discovery of new charged charmonium like structures. Two isospin triplets Z(3900) and Z(4020) have been discovered, decaying into π±J/ψ and π±hc, respectively. Structures with compatible parameters have been found decaying to DD̄∗ and D∗D̄∗, respectively, suggesting that these structures might be of the same origin. Furthermore, we have investigated the transition Y(4260) → γX(3872). This is the first observation of a radiative transition between XYZ states.

Heavy quarkonium: progress, puzzles, and opportunities
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 p...
متن کاملRequest for funds for a high accuracy beam energy measurement system for BESIII
The precise determination of the beam energy at BESIII is extremely important for many physics analyses, in particular, for the precise measurement of the τ mass. Fortunately, a method has been developed by physicists from the Budker Institute of Nuclear Physics (BINP) using back scattered Compton photons produced by CO2 laser beams on both the electron and positron beams in BESIII. This method...
متن کاملCosmic ray test results on resistive plate chamber for the BESIII experiments
A cosmic ray test system has been built to fully qualify the resistive plate chambers for the MUON system of the BESIII experiment. The setup has been designed to measure detector’s performance and to verify the stability and reliability of the MUON system. The same electronics, similar readout method and data analysis for BESIII MUON system have been used for this station. With this station, t...
متن کاملBEPCII and BESIII
The Beijing Electron Collider is being upgraded (BEPCII) to a two-ring collider with a design luminosity of 1 × 10cm s at a center-of-mass energy of 3.89 GeV. It will operate between 2 and 4.2 GeV in the center of mass. With this luminosity, the BESIII detector will be able to collect, for example, 10 billion J/ψ events in one year of running. This will be a unique facility in the world opening...
متن کاملComment on " the Massive Thirring Model from Xyz Spin Chain " by Kolanovic Et Al
It is shown that the continuum limit of the spin 1/2 Heisenberg XYZ model is far from sufficient for the site number of 16. Therefore, the energy spectrum of the XYZ model obtained by Kolanovic et al. has nothing to do with the massive Thirring model, but it shows only the spectrum of the finite size effects. The spin 1/2 Heisenberg model is a rich theory, which contains a variety of field theo...
