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 ...
Probing CP symmetry and weak phases with entangled double-strange baryons
(NATURE RESEARCH, 2022)
Though immensely successful, the standard model of particle physics does not offer any explanation as to why our Universe contains so much more matter than antimatter. A key to a dynamically generated matter-antimatter ...
