Several intermediate states of the reaction channels e+e– → π+π– D0¯D0 and e+e– → π+π–D+D– are studied using the data samples collected with the BESIII detector at center-of-mass energies above 4.08 GeV. For the first time in this final state, a ψ(3770) signal is seen in the D¯D invariant mass spect...

description Several intermediate states of the reaction channels e+e– → π+π– D0¯D0 and e+e– → π+π–D+D– are studied using the data samples collected with the BESIII detector at center-of-mass energies above 4.08 GeV. For the first time in this final state, a ψ(3770) signal is seen in the D¯D invariant mass spectrum, with a statistical significance of 5.2σ at √s = 4.42 GeV. There is also evidence for this resonance at √s = 4.26 and 4.36 GeV with statistical significance of 3.2σ and 3.3σ, respectively. In addition, the Born cross section of e+e– → π+π– ψ(3770) is measured.

For the first time in this final state, a ψ(3770) signal is seen in the D¯D invariant mass spectrum, with a statistical significance of 5.2σ at √s = 4.42 GeV. There is also evidence for this resonance at √s = 4.26 and 4.36 GeV with statistical significance of 3.2σ and 3.3σ, respectively. In addition, the Born cross section of e+e– → π+π– ψ(3770) is measured.</abstract><cop>United States</cop><pub>American Physical Society (APS)</pub><doi>10.1103/PhysRevD.100.032005</doi></addata></record>
