Study of the electromagnetic Dalitz decay $J / I ¨ \to e^{+} e^{-} I ¨ ^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +640

We report the first measurement of the di-electron invariant mass dependent transition form factor in the electromagnetic Dalitz decay $J / I ¨ \to e^{+} e^{-} I ¨ ^{0}$ using $(10087 \pm 44) \…

Observation of strong nuclear suppression in exclusive $J / I ¨ $ photoproduction in Au $+$ Au ultra-peripheral collisions at RHIC

STAR Collaboration

We report a measurement of exclusive $J / I ¨ $ photoproduction in Au $+$ Au ultra-peripheral collisions at $s_{_{NN}} = 200$ GeV using the STAR detector. For the first time,…
