Precise measurements of and decays
BESIII Collaboration, M. Ablikim, M. N. Achasov +758
Using collision data corresponding to an integrated luminosity of 20.3 fb, collected at the center-of-mass energy of 3.773 GeV with the BESIII detector, we present…
First Experimental Constraint on the Scalar Current in the Transition
BESIII Collaboration, M. Ablikim, M. N. Achasov +758
Using 20.3 fb of collision data taken at the center-of-mass energy of GeV, we report the first experimental constraint on the scalar current in the…
First observation of the decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +761
Using events collected with the BESIII detector at the BEPCII collider, we report the first observation of the decay $η_{c} \to Î^{0} \barÎ^{0}…
