Amplitude Analysis of the Decays eta ' -> pi(+)pi(-)pi(0) and eta' -> pi(0)pi(0)pi(0)
(Amer Physic Soc., 2017)
Based on a sample of 1.31 x 10(9) J/Psi events collected with the BESIII detector, an amplitude analysis of the isospin-violating decays eta' -> pi(+)pi(-)pi(0) and eta' -> pi(0)pi(0)pi(0) is performed. A significant P-wave ...
Measurement of integrated luminosity and center-of-mass energy of data taken by BESIII at root s=2.125 GeV
(Chinese Physical, 2017)
To study the nature of the state Y (2175), a dedicated data set of e(+)e(-) collision data was collected at the center-of-mass energy of 2.125 GeV with the BESIII detector at the BEPCII collider. By analyzing large-angle ...
Study of decay dynamics and CP asymmetry in D+ ? KL0 e+?e decay
(American Physical Society, 2015)
Using 2.92 fb-1 of electron-positron annihilation data collected at s=3.773 GeV with the BESIII detector, we obtain the first measurements of the absolute branching fraction B(D+?KL0e+?e)=(4.481±0.027(stat)±0.103(sys))% ...
Evidence of Two Resonant Structures in e(+)e(-)->pi(+) pi(-) h(c)
(Amer Physic Soc., 2017)
The cross sections of e(+)e(-) -> pi(+) pi(-) hc at center-of-mass energies from 3.896 to 4.600 GeVare measured using data samples collected with the BESIII detector operating at the Beijing Electron Positron Collider. The ...

We report the first direct measurement of decays of the Lambda(+)(c) baryon involving the neutron. The analysis is performed using 567 pb(-1) of e(+)e(-) collision data collected at root s = 4.599 GeV with the BESIII ...
Search for psi(3686)-> gamma eta(c)(eta(1405)) -> gamma pi(+)pi(-)pi(0)
(Amer Physical Soc., 2017)
Using a sample of 448.1 x 10(6) psi(3686) events collected with the BESIII detector, a search for the isospin violating decay eta(c) -> pi(+) pi(-) pi(0) via psi(3686) -> gamma eta(c) is presented. No signal is observed, ...
Measurement of the leptonic decay width of J/psi using initial state radiation
(Elsevier, 2016)
Using a data set of 2.93 fb(-1) taken at a center-of-mass energy of root s = 3.773 GeV with the BESIII detector at the BEPCII collider, we measure the process e(+) e(-) -> J/psi gamma -> mu(+)mu(-)gamma and determine the ...
Evidence for the singly Cabibbo suppressed decay Lambda(+)(c) -> p eta and search for Lambda(+)(c) -> p pi(0)

We study the singly Cabibbo suppressed decays Lambda(+)(c) -> p eta and Lambda(+)(c) -> p pi(0) using Lambda(+)(c)(Lambda) over bar (-)(c) pairs produced by e(+)e(-) collisions at a center-of-mass energy of root s = 4.6 ...
Observation of the helicity-selection-rule suppressed decay of the chi(c2) charmonium state
(Amer Physical Soc., 2017)
The decays of chi(c2) -> K+K- pi(0), KSK +/-pi(-/+), and pi(+)pi(-)pi(0) are studied with the psi(3686) data samples collected with the Beijing Spectrometer ( BESIII). For the first time, the branching fractions of chi(c2) ...
