Measurement of e(+)e(-)-> K+K-pi(0) Cross Section and Observation of a Resonant Structure
(Springer, 2022)
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 ...
Context Sensitive Links 19 of 21 Cross section Measurements of the e(+)e(-) -> D*D+*(-) and e(+)e(-) -> D*D-+(-) Processes at Center-of-Mass Energies from 4.085 to 4.600 GeV
(Springer, 2022)
The Born cross sections of the e(+)e(-) -> D*D+*(-) and e(+)e(-) -> D*D-+(-) processes are measured using e(+)e(-) collision data collected with the BESIII experiment at center-of-mass energies from 4.085 to 4.600 GeV, ...
Measurements of Absolute Branching Fractions of D-0 -> K-L(0)phi, K-L(0)eta, K-L(0)omega, and K-L(0)eta '
(Amer Physical Soc., 2022)
We report the first measurements of the absolute branching fractions of D-0 -> K-L(0)phi, D-0 -> K-L(0)eta, D-0 -> K-L(0)omega, and D-0 -> K-L(0)eta', by analyzing 2.93 fb(-1) of e(+) e(-) collision data taken at a ...
Search for a massless dark photon in Λc+ →pγ′ decay
(American Physical Society, 2022)
A search for a massless dark photon γ′ is conducted using 4.5 fb-1 of e+e- collision data collected at center-of-mass energies between 4.600 and 4.699 GeV with the BESIII detector at BEPCII. No significant signal is observed, ...

(SPRINGER, 2022)
The Born cross sections of the processes e(+)e(-) -> omega pi(0) and e(+)e(-) -> omega eta are measured at center-of-mass energies between 3.773 and 4.701 GeV using a total integrated luminosity of 22.7 fb(-1) collected ...
Observation of D0(+) -> K-S(0)pi(0(+))omega and improved measurement of D-0 -> K- pi(+)omega
(AMER PHYSICAL SOC, 2022)
By analyzing an e(+)e(-) annihilation data sample with an integrated luminosity of 2.93 fb(-1) taken at the center-of-mass energy of 3.773 GeV with the BESIII detector, we determine the absolute branching fractions of the ...

Using a data sample corresponding to an integrated luminosity of 2.93 fb(-1) collected at a center-of-mass energy root s = 3.773 GeV by the BESIII detector, the decay D-0 -> omega phi is observed for the first time. The ...
First Observation of the Direct Production of the chi(c1) in e(+)e(-) Annihilation
(AMER PHYSICAL SOC, 2022)
We study the direct production of the J(PC) = 1(++) charmonium state chi(c1)(1P) in electron-positron annihilation by carrying out an energy scan around the mass of the chi(c1)(1P). The data were collected with the BESIII ...
Study of the h(c)(1(1)P(1)) meson via psi(2S) -> pi(0)h(c) decays at BESIII
(AMER PHYSICAL SOC, 2022)
Using 448 million psi(2S) events, the spin-singlet P-wave charmonium state h(c)(1(1)P(1)) is studied via the psi(2S) -> pi(0)h(c) decay followed by the h(c) -> gamma eta(c) transition. The branching fractions are measured ...
