Measurement of e(+)e(-) -> pi(0)pi(0)psi(3686) at root s from 4.009 to 4.600 GeV and observation of a neutral charmoniumlike structure
(Amer Physical Soc., 2018)
Using ethorne-collision data collected with the BESIII detector at the BEPCII collider corresponding to an integrated luminosity of 5.2 fb(-1) at center-of-mass energies (root s) from 4.009 to 4.600 GeV, the process e(+)e(-) ...
Measurements of the branching fractions for D+ -> (KSKSK+)-K-0-K-0+, (KSKS0)-K-0 pi + and D-0 -> (KSKS0)-K-0, (KSKSKS0)-K-0-K-0
(Elsevier Science, 2017)
By analyzing 2.93 fb(-1) of data taken at the psi(3770) resonance peak with the BESIII detector, we measure the branching fractions for the hadronic decays D+ -> (KSKSK+)-K-0-K-0, D+ -> (KSKS0)-K-0 pi(+), D-0 -> (KSKS0)-K-0 ...
Evidence for e(+)e(-)->gamma chi c1,2 at center-of-mass energies from 4.009 to 4.360 GeV
(IOP PUBLISHING LTD, 2015)
Using data samples collected at center-of-mass energies of root s=4.009, 4.230, 4.260, and 4.360 GeV with the BESIII detector operating at the BEPCII collider, we perform a search for the process e(+)e(-)->gamma chi(cJ) ...

Study of e+e- ???cJ at center of mass energies from 4.21 to 4.42 GeV
(American Physical Society, 2015)
Based on data samples collected with the BESIII detector at the BEPCII collider at nine center of mass energies from 4.21 to 4.42 GeV, we search for the production of e+e-???cJ (J=0, 1, 2). The process e+e-???c0 is observed ...
Amplitude analysis of the chi(c1) -> eta pi(+)pi(-) decays
(Amer Physical Soc., 2017)
Using 448.0 x 10(6) psi(3686) events collected with the BESIII detector, an amplitude analysis is performed for psi(3686) -> gamma chi(c1), chi(c1) ->eta pi(+)pi(-) decays. The most dominant two- body structure observed ...
An improved limit for ?ee of X(3872) and ?ee measurement of ?(3686)
(Elsevier, 2015)
Using the data sets taken at center-of-mass energies above 4 GeV by the BESIII detector at the BEPCII storage ring, we search for the reaction e+e-??ISRX(3872)??ISR?+?-J/? via the Initial State Radiation technique. The ...
Measurement of B(psi(3770) -> gamma chi(c1)) and search for psi(3770) -> gamma chi(c2)
(American Physical Society, 2015)
We report a measurement of the branching fraction for ?(3770)???c1 and search for the transition ?(3770)???c2 based on 2.92 fb-1 of e+e- data accumulated at s=3.773 GeV with the BESIII detector at the BEPCII collider. We ...
Measurement of the matrix elements for the decays eta -> pi(+)pi(-)pi(0) and eta/eta ' -> pi(0)pi(0)pi(0)
(American Physical Society, 2015)
Based on a sample of 1.31×109 J/? events collected with the BESIII detector at the BEPCII collider, Dalitz plot analyses of selected 79,625 ???+?-?0 events, 33,908 ???0?0?0 events, and 1,888 ????0?0?0 events are performed. ...
