Using 𝑒+𝑒- collision data, corresponding to an integrated luminosity of 892 pb^-1 collected at center-of-mass energies from 4.84 to 4.95 GeV with the BESIII detector, we search for the process 𝑒+𝑒-→𝐾+𝐾-𝜓(3770) by reconstructing two charged kaons and one 𝐷 meson from 𝜓(3770). No significant signal of 𝑒+𝑒−→𝐾+𝐾-𝜓(3770) is found and the upper limits of the Born cross sections are reported at 90% confidence level.

Abstract
Using 𝑒+𝑒- collision data, corresponding to an integrated luminosity of 892 pb^-1 collected at center-of-mass energies from 4.84 to 4.95 GeV with the BESIII detector, we search for the process 𝑒+𝑒-→𝐾+𝐾-𝜓(3770) by reconstructing two charged kaons and one 𝐷 meson from 𝜓(3770). No significant signal of 𝑒+𝑒−→𝐾+𝐾-𝜓(3770) is found and the upper limits of the Born cross sections are reported at 90% confidence level.File in questo prodotto:
