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 ...
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 ...
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, ...
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 ...
Amplitude analysis and branching fraction measurement of the decay D-s(+) -> K+pi(+)pi(-)
(SPRINGER, 2022)
Using 6.32 fb(-1) of e(+)e(-) collision data 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 decay D-s(+) -> K+pi(+)pi(-) and determine ...
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 ...
