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, ...
Cross section measurement of e(+)e(-) -> pi(+) pi(-) psi (3686) from root s=4.0076 GeV to 4.6984 GeV
(American Physical Society, 2021)
The first amplitude analysis of the decay Ds+→K-K+π+π0 is presented using the data samples, corresponding to an integrated luminosity of 6.32 fb-1, collected with the BESIII detector at e+e- center-of-mass energies between ...
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 ...
Amplitude analysis and branching fraction measurement of D-s(+) -> K-K+pi(+)pi(+)pi(-)
(Springer Science and Business Media Deutschland GmbH, 2022)
Using e+e− annihilation data corresponding to a total integrated luminosity of 6.32 fb−1 collected at the center-of-mass energies between 4.178 and 4.226 GeV with the BESIII detector, we perform an amplitude analysis of ...

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, ...
Cross section measurement of e(+)e(-) -> (KSKL0)-K-0 at root s=2.00-3.08 GeV
(American Physical Society, 2021)
The cross sections of the process e+e-→KS0KL0 are measured at fifteen center-of-mass energies s from 2.00 to 3.08 GeV with a total integrated luminosity of 582 pb-1 and using the BESIII detector at the Beijing Electron ...
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 ...
