There has recently been a dramatic renewal of interest in hadron spectroscopy and charm physics.This renaissance has been driven in part by the discovery of a plethora of charmonium-like XYZ states at BESⅢand B factories,and the observation of an intriguing proton-antiproton threshold enhancement and the possibly related X(1835)meson state at BESⅢ,as well as the threshold measurements of charm mesons and charm baryons.We present a detailed survey of the important topics in tau-charm physics and hadron physics that can be further explored at BESⅢduring the remaining operation period of BEPCⅡ.This survey will help in the optimization of the data-taking plan over the coming years,and provides physics motivation for the possible upgrade of BEPCⅡto higher luminosity. 展开更多

Studies of e^+e~→D_s^+■(*0)K^-and the P-wave charmed-strange mesons are performed based on an e^+e^-collision data sample corresponding to an integrated luminosity of 567 pb-1 collected with the BESIII detector at s1/2=4.600 GeV. The processes of e^+e^-→D_s^+■*0K^- and D_s^+■~0K^- are observed for the first time and are found to be dominated by the modes D_s^+Ds1(2536)^-and D_s^+Ds2~*(2573)^-, respectively. The Born cross sections are measured to be σ~B(e^+e^-→D_s^+■*0K^-) =(10.1±2.3±0.8) pb and σ~B(e^+e^-→D_s^+■~0K^-) =(19.4±2.3± 1.6) pb, and the products of Born cross section and the decay branching fraction are measured to be σ~B(e^+e^-→D_s^+Ds1(2536)^-+c.c.)·B(Ds1(2536)^-→■*0K^-)=(7.5±1.8±0.7) pb and σ~B(e^+e^-→D_s^+Ds2~*(2573)^-+ c.c.)·B(Ds2~*(2573)^-→■~0 K^-)=(19.7 ± 2.9 ±2.0) pb. For the Ds1(2536)^-and Ds2~*(2573)^-mesons, the masses and widths are measured to be M(Ds1(2536)^-)=(2537.7±0.5 ±3.1) MeV/c2, Γ(Ds1(2536)^-) =(1.7 ±1.2 ±0.6)MeV, and M(Ds2~*(2573)^-)=(2570.7±2.0 ±1.7) MeV/c^2, Γ(Ds2~*(2573)^-)=(17.2 ±3.6 ±1.1) MeV. The spin-parity of the Ds2~*(2573)^-meson is determined to be J^p= 2^+. In addition, the processes e^+e^-→D_s^+■(*0)K^-are searched for using the data samples taken at four(two) center-of-mass energies between 4.416(4.527) and 4.575 GeV, and upper limits at the 90% confidence level on the cross sections are determined. 展开更多

To investigate the nature of theΨ(3770)resonance and to measure the cross section for e^+e^-→DD,a cross-section scan data sample,distributed among 41 center-of-mass energy points from 3.73 to 3.89 GeV,was taken with the BESIII detector operated at the BEPCII collider in the year 2010.By analyzing the large angle Bhabha scattering events,we measure the integrated luminosity of the data sample at each center-of-mass energy point.The total integrated luminosity of the data sample is 76.16±0.04±0.61 pb^-1,where the first uncertainty is statistical and the second systematic. 展开更多

- 摘要 There has recently been a dramatic renewal of interest in hadron spectroscopy and charm physics.This renaissance has been driven in part by the discovery of a plethora of charmonium-like XYZ states at BESⅢand B factories,and the observation of an intriguing proton-antiproton threshold enhancement and the possibly related X(1835)meson state at BESⅢ,as well as the threshold measurements of charm mesons and charm baryons.We present a detailed survey of the important topics in tau-charm physics and hadron physics that can be further explored at BESⅢduring the remaining operation period of BEPCⅡ.This survey will help in the optimization of the data-taking plan over the coming years,and provides physics motivation for the possible upgrade of BEPCⅡto higher luminosity.

- 摘要 Studies of e^+e~→D_s^+■(*0)K^-and the P-wave charmed-strange mesons are performed based on an e^+e^-collision data sample corresponding to an integrated luminosity of 567 pb-1 collected with the BESIII detector at s1/2=4.600 GeV. The processes of e^+e^-→D_s^+■*0K^- and D_s^+■~0K^- are observed for the first time and are found to be dominated by the modes D_s^+Ds1(2536)^-and D_s^+Ds2~*(2573)^-, respectively. The Born cross sections are measured to be σ~B(e^+e^-→D_s^+■*0K^-) =(10.1±2.3±0.8) pb and σ~B(e^+e^-→D_s^+■~0K^-) =(19.4±2.3± 1.6) pb, and the products of Born cross section and the decay branching fraction are measured to be σ~B(e^+e^-→D_s^+Ds1(2536)^-+c.c.)·B(Ds1(2536)^-→■*0K^-)=(7.5±1.8±0.7) pb and σ~B(e^+e^-→D_s^+Ds2~*(2573)^-+ c.c.)·B(Ds2~*(2573)^-→■~0 K^-)=(19.7 ± 2.9 ±2.0) pb. For the Ds1(2536)^-and Ds2~*(2573)^-mesons, the masses and widths are measured to be M(Ds1(2536)^-)=(2537.7±0.5 ±3.1) MeV/c2, Γ(Ds1(2536)^-) =(1.7 ±1.2 ±0.6)MeV, and M(Ds2~*(2573)^-)=(2570.7±2.0 ±1.7) MeV/c^2, Γ(Ds2~*(2573)^-)=(17.2 ±3.6 ±1.1) MeV. The spin-parity of the Ds2~*(2573)^-meson is determined to be J^p= 2^+. In addition, the processes e^+e^-→D_s^+■(*0)K^-are searched for using the data samples taken at four(two) center-of-mass energies between 4.416(4.527) and 4.575 GeV, and upper limits at the 90% confidence level on the cross sections are determined.

- 摘要 We study the hadronic decays of∧c+to the final states∑+ηand∑+η’,using an e+e-annihilation data sample of 567 pb-1 taken at a center-of-mass energy of 4.6 GeV with the BESIII detector at the BEPCⅡcollider.We find evidence for the decays∧c+→∑+ηand∑+η’with statistical significance of 2.5σand 3.2σ,respectively.Normalizing to the reference decays∧c+→∑+π0 and∑+ω,we obtain the ratios of the branching fractions■and■to be 0.35±0.16±0.02 and 0.86±0.34±0.04,respectively.The upper limits at the 90%confidence level are set to be■and■.Using BESIII measurements of the branching fractions of the reference decays,we determine B(∧c+→∑+η)=(0.41±0.19±0.05)%(<0.68%)and B(∧c+→∑+η’)=(1.34±0.53±0.19)%(<1.9%).Here,the first uncertainties are statistical and the second systematic.The obtained branching fraction of∧c+→∑+ηis consistent with the previous measurement,and the branching fraction of∧c+→∑+η’is measured for the first time.

- 摘要 To investigate the nature of theΨ(3770)resonance and to measure the cross section for e^+e^-→DD,a cross-section scan data sample,distributed among 41 center-of-mass energy points from 3.73 to 3.89 GeV,was taken with the BESIII detector operated at the BEPCII collider in the year 2010.By analyzing the large angle Bhabha scattering events,we measure the integrated luminosity of the data sample at each center-of-mass energy point.The total integrated luminosity of the data sample is 76.16±0.04±0.61 pb^-1,where the first uncertainty is statistical and the second systematic.
