Observation of e(+)e(-) -> omega chi(c1,2) near root s=4.42 and 4.6 GeV
(2016)BEPC-BES. Based on data samples collected with the BESIII detector operating at the BEPCII storage ring at center-of-mass energies s?>s> 4.4 GeV, the processes e+e-›??c1,2e+e-›??c1,2 are observed for the first time. With ... -
Measurement of azimuthal asymmetries in inclusive charged dipion production in e + e - annihilations at ? s = 3.65 GeV
(APS Physics, 2016)We present a measurement of the azimuthal asymmetries of two charged pions in the inclusive process e(+) e(-) -> pi pi X based on a data set of 62 pb(-1) at the center-of-mass energy of 3.65 GeV collected with the SESIII ... -
Measurement of the e+e- › ?+?- cross section between 600 and 900 MeV using initial state radiation
(Elsevier, 2016)We extract the e+e-›?+?- cross section in the energy range between 600 and 900 MeV, exploiting the method of initial state radiation. A data set with an integrated luminosity of 2.93 fb-1 taken at a center-of-mass energy ... -
