Mass creation by the strong interaction: Glueballs -- status and perspectives
Ulrich Wiedner
Glueballs represent a fascinating aspect of the strong interaction in nature. Gluons that serve as the mediators of the strong interaction are massless particles, but they possess…
First measurement of and cross sections via -nucleus scattering at an electron-positron collider
BESIII Collaboration, M. Ablikim, M. N. Achasov +678
Using events collected with the BESIII detector at the BEPCII storage ring, the reactions and $Σ^{+}n\rightarrowΣ^…
Observation of
BESIII Collaboration, M. Ablikim, M. N. Achasov +677
Using events collected by the BESIII detector operating at the BEPCII storage ring, the decays are…
Study of and in the decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +666
We perform an amplitude analysis of the decay and measure its absolute branching fraction to be $(1.016 \pm 0.013_{\text {stat.}} \pm 0.014_{\text {syst.}})…
Evidence for the semileptonic decays
BESIII Collaboration, M. Ablikim, M. N. Achasov +680
Using of collision data collected by the BESIII detector at center-of-mass energies between and , we search for the semileptonic decays…
Measurement of branching fractions of decays to and
BESIII Collaboration, M. Ablikim, M. N. Achasov +650
By analyzing collision data taken at center-of-mass energies between 4.600 and 4.699 GeV with the BESIII detector at the BEPCII collider, corresponding to an in…
