Observation of the decay D-0 -> rho - mu + nu(mu)
(AMER PHYSICAL SOC, 2021)
By analyzing an e(+)e(-) annihilation data sample corresponding to an integrated luminosity of 2.93 fb(- 1) collected at a center-of-mass energy of 3.773 GeV with the BESIII detector, we measure the branching fraction of ...
Measurement of A baryon polarization in e(+) e(-) -> Lambda(Lambda)over-bar at root s=3.773 GeV
(AMER PHYSICAL SOC, 2022)
Using a data sample of psi(3770) events collected with the BESIII detector at BEPCII corresponding to an integrated luminosity of 2.9 fb-1, we report a measurement of A spin polarization in e+ e- -> Lambda(Lambda) over bar ...
Luminosities and energies of e(+)e(-) collision data taken between root s=4.61 gev and 4.95 gev at BESIII
(IOP Publishing Ltd, 2022)
From December 2019 to June 2021, the BESIII experiment collected approximately 5.85 fb(-1) of data at center-of-mass energies between 4.61 and 4.95 GeV. This is the highest collision energy BEPCII has reached to date. The ...
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, ...
Number of J/psi events at BESIII
(IOP Publishing, 2022)
Using inclusive decays of J/psi, a precise determination of the number of J/psi events collected with the BESIII detector was performed. For the two data sets taken in 2009 and 2012, the numbers of J/psi events were ...
Observation of chi(cJ) -> lambda(lambda)over-bar(eta)
(PHYSICAL REVIEW D, 2022)
By analyzing (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the BESIII detector operating at the BEPCII collider, the decays of chi(cJ) -> Lambda(Lambda) over bar (eta) (J = 0, 1, and 2) are observed for the first ...
Cross section measurements of the processes e(+)e(-) -> omega pi(0) and omega eta at center-of-mass energies between 3.773 and 4.701 GeV
(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 ...
Measurement of psi(3686) -> lambda(lambda)over-bar eta and psi(3686) -> lambda(lambda)over-bar pi(0) decays
(AMER PHYSICAL SOC, 2022)
Based on a sample of 448.1 x 10(6) psi(3686) events collected with the BESIII detector, a study of psi(3686) -> Lambda(Lambda) over bar pi(0) and psi(3686) -> Lambda(Lambda) over bar eta is performed. Evidence of the ...
Search for X(3872) -> pi(0)chi(c0) and X(3872) -> pi pi chi(c0) at BESIII
(AMER PHYSICAL SOC, 2022)
Using 9.9 fb(-1) of e(+)e(-) collision data collected by the BESIII detector at center-of-mass energies between 4.15 and 4.30 GeV, we search for the processes e(+)e(-) -> gamma(X)(3872) with X(3872) -> pi(0)chi(c0) and ...
Search for the decay h(c) -> pi(0) J/psi
(SPRINGER, 2022)
A search for the decay h(c) -> pi(0) J/psi is performed using a sample of h(c) produced in the reaction e(+)e(-) -> pi(+)pi(-)h(c). The data samples were collected with the BESIII detector at center-of-mass energies between ...
