Measurement of coherent exclusive $J/\ddot{I}ˆ\to \hat{I}{¼}^{+}\hat{I}{¼}^{-}$ production in ultraperipheral Pb+Pb collisions at $\sqrt{s_{\text{NN}}}=5.36$ TeV with the ATLAS detector

ATLAS Collaboration

The ATLAS experiment has performed a measurement of coherent exclusive $J/\ddot{I}ˆ\to \hat{I}{¼}^{+}\hat{I}{¼}^{-}$ production in ultraperipheral Pb+Pb collisions at $\sqrt{s_{\text{NN}}}=5.36$ TeV. The da…
