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) \…

A search for $R$ -parity violating supersymmetric decays of the top squark to a $b$ -jet and a lepton in $s$ = 13 TeV $pp$ collisions with the ATLAS detector

ATLAS Collaboration

A search is presented for direct pair production of the stop, the supersymmetric partner of the top quark, in a decay through an $R$ -parity violating coupling to a charged lepton a…
