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 ...
Search for a CP-odd light Higgs boson in J/psi -> gamma A(0)
(AMER PHYSICAL SOC, 2022)
Using J/psi radiative decays from 9.0 billion J/psi events collected by the BESIII detector, we search for di-muon decays of a CP-odd light Higgs boson (A(0)), predicted by many new physics models beyond the Standard Model, ...
Study of the process e(+)e(-) -> phi eta at center-of-mass energies between 2.00 and 3.08 GeV
(2021)
The process e(+)e(-) -> phi eta is studied at 22 center-of-mass energy points (root s) between 2.00 and 3.08 GeV using 715 pb(-1) of data collected with the BESIII detector. The measured Born cross section of e(+)e(-) -> ...
Search for new hadronic decays of h(c) and observation of h(c) -> p(p)over-bar eta
(SPRINGER, 2022)
A search for the hadronic decays of the h(c) meson to the final states p (p) over bar pi(+)pi(-)pi(0), p (p) over bar eta and p (p) over bar pi(0) via the process psi(3686) -> pi(0)(h)c is performed using (4.48 +/- 0.03) ...
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, ...
Study of the processes chi(cJ) -> Xi(-)(Xi)over-bar(+) and Xi(0)(Xi)over-bar(0)
(SPRINGER, 2022)
Using 448.1 x 10(6) psi(3686) decays collected with the BESIII detector at the BEPCII e(+)e(-) storage rings, the branching fractions and angular distributions of the decays chi(cJ) -> Xi(-)(Xi) over bar (+) and Xi(0)(Xi) ...
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 ...
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 ...
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 ...
