Abstract: Using data taken at 29 center-of-mass energies between 4.16 and 4.70 GeV with the BESIII detector at the Beijing Electron Positron Collider corresponding to a total integrated luminosity of approximately 18.8 , the process is observed for the first time with a statistical significance of . The average Born cross sections in the energy ranges of (4.160, 4.380) GeV, (4.400, 4.600) GeV and (4.610, 4.700) GeV are measured to be fb, fb and fb, respectively, where the first uncertainties are statistical and the second are systematic. The line shapes of the and invariant mass spectra are consistent with phase space distributions, indicating that no hexaquark or di-baryon state is observed.

Abstract: Using electron-positron annihilation data samples corresponding to an integrated luminosity of 4.5 fb , collected by the BESIII detector in the energy region between and , we report the first observations of the Cabibbo-suppressed decays , , and the Cabibbo-favored decay with statistical significances of , , and 10\sigma $?> , respectively. The branching fractions of these decays are measured to be %, %, and %, where the first uncertainties are statistical and the second are systematic. We find that the branching fraction of the decay is about one order of magnitude higher than that of .

Abstract: The cross sections of at center-of-mass energies from 4.127 to 4.600 GeV are measured based on 15.6 fb data collected with the BESIII detector operating at the BEPCII storage ring. Two resonant structures are observed in the line shape of the cross sections. The mass and width of the first structure are measured to be ( ) MeV and ( ) MeV, respectively. They are consistent with those of the established . The second structure is observed for the first time with a statistical significance greater than 8σ, denoted as . Its mass and width are determined to be ( ) MeV and ( ) MeV, respectively. The first presented uncertainties are statistical and the second ones are systematic. The product of the electronic partial width with the decay branching fraction is reported.

Abstract: We report new measurements of the cross sections for the production of DD̄ final states at the ψ(3770) resonance. Our data sample consists of an integrated luminosity of 2.93 fb−1 of e+e− annihilation data produced by the BEPCII collider and collected and analyzed with the BESIII detector. We exclusively reconstruct three D0 and six D+ hadronic decay modes and use the ratio of the yield of fully reconstructed DD̄ events (“double tags”) to the yield of all reconstructed D or D̄ mesons (“single tags”) to determine the number of D0D̄0 and D+D− events, benefiting from the cancellation of many systematic uncertainties. Combining these yields with an independent determination of the integrated luminosity of the data sample, we find the cross sections to be σ(e+e− → D0D̄0) nb and σ(e+e− → D+D−) = (2.830 ± 0.011 ± 0.026) nb, where the uncertainties are statistical and systematic, respectively.

Abstract: To investigate the nature of the (3770) resonance and to measure the cross section for , 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 , where the first uncertainty is statistical and the second systematic.

Abstract: To study the nature of the state Y (2175), a dedicated data set of e+eâ collision data was collected at the center-of-mass energy of 2.125 GeV with the BESIII detector at the BEPCII collider. By analyzing large-angle Bhabha scattering events, the integrated luminosity of this data set is determined to be 108.49Â±0.02Â±0.85Â pbâ1, where the first uncertainty is statistical and the second one is systematic. In addition, the center-of-mass energy of the data set is determined with radiative dimuon events to be 2126.55Â±0.03Â±0.85Â MeV, where the first uncertainty is statistical and the second one is systematic.

Abstract: A measurement of the number of J/ψ events collected with the BESIII detector in 2009 and 2012 is performed using inclusive decays of the J/ψ. The number of J/ψ events taken in 2009 is recalculated to be (223.7 ± 1.4) × 106, which is in good agreement with the previous measurement, but with significantly improved precision due to improvements in the BESIII software. The number of J/ψ events taken in 2012 is determined to be (1086.9 ± 6.0) × 106. In total, the number of J/ψ events collected with the BESIII detector is measured to be (1310.6 ± 7.0) × 106, where the uncertainty is dominated by systematic effects and the statistical uncertainty is negligible.

Abstract: From 2011 to 2014, the BESIII experiment collected about 5 fb−1 data at center-of-mass energies around 4 GeV for the studies of the charmonium-like and higher excited charmonium states. By analyzing the di-muon process e+e− → γISR/FSRμ+μ−, the center-of-mass energies of the data samples are measured with a precision of 0.8 MeV. The center-of-mass energy is found to be stable for most of the time during data taking.

Abstract: The numbers of ?(3686) events accumulated by the BESIII detector for the data taken during 2009 and 2012 are determined to be (107:0±0:8) ×106 and (341:1±2:1)×106 , respectively, by counting inclusive hadronic events, where the uncertainties are systematic and the statistical uncertainties are negligible. The number of events for the sample taken in 2009 is consistent with that of the previous measurement. The total number of ?(3686) events for the two data taking periods is (448:1±2:9)×106 . © Article funded by SCOAP3 and published under licence by Chinese Physical Society and the Institute of High Energy Physics of the Chinese Academy of Sciences and the Institute of Modern Physics of the Chinese Academy of Sciences and IOP Publishing Ltd., DPT2006K-120470, 11205082 CRC 1044 11235011, 11425524, 11335008, 11322544, 11475207 530-4CDP03 DE-FG02-05ER41374, DE-SC-0010118, DE-SC-0010504 2009CB825200 GSI: GSI SCOAP3 KJCX2-YW-N29, U1532258, KJCX2-YW-N45, 11179007, U1232201, U1532257, 11079008, 11179014 NRF: R32-2008-000-10155-0, Received 13 September 2017, Revised 2 December 2017, Published online 5 January 2018 ?
