On November 19th, the collision luminosity of the upgraded Beijing Electron Positron Collider (BEPCII) hit another new record, achieving 8.04×10³²cm^-2s^-1 at an energy of 1.89 GeV.

This smashes the record made just a day earlier, when in the latest round of BEPCII commissioning, the collision luminosity reached 7.15×10³²cm^-2s^-1 on Nov.18, breaking the earlier record of 7.08×10³²cm^-2s^-1 made in March, 2013.

With the excellent performance of BEPCII in this round, we believe there is more exciting news from BEPCII yet to come.
