Amplitude Analysis and Branching-Fraction Measurement of D-s(+) -> pi(+)pi(0)eta '
Using data collected with the BESIII detector in e(+)e(-) collisions at center-of-mass energies between 4.178 and 4.226 GeV and corresponding to 6.32 fb(-1) of integrated luminosity, we report the amplitude analysis and ...
Measurement of e(+)e(-)-> K+K-pi(0) Cross Section and Observation of a Resonant Structure
Based on e(+)e(-) collision data collected by the BESIII detector at the BEPCII collider at center-of-mass energies from 2.000 to 3.080 GeV, a partial-wave analysis is performed for the process e(+)e(-)-> K+K-pi(0). The ...
Observation of e(+)e(-)-> eta psi(2S) at Center-of-Mass Energies from 4.236 to 4.600 GeV
Using a total of 5.25 fb(-1) of e(+)e(-) collision data with center-of-mass energies from 4.236 to 4.600 GeV, we report the first observation of the process e(+)e(-)-> eta psi(2S) with a statistical significance of 4.9 ...
