Measurement of the absolute branching fraction of the inclusive decay Lambda c+-> KS0X: (BESIII Collaboration)
(Springer, 2020)
We report the first measurement of the absolute branching fraction of the inclusive decay Lambda c+-> KS0X. The analysis is performed using an e+e- collision data sample corresponding to an integrated luminosity of 567 ...
Study of the process e(+) e(-) -> pi(0)pi(0)J/psi and neutral charmoniumlike state Z(c)(3900)(0)
(Amer Physical Soc., 2020)
Cross sections of the process e(+)e(-) -> pi(0)pi(0)J/psi at center-of-mass energies between 3.808 and 4.600 GeV are measured with high precision by using 12.4 fb(-1) of data samples collected with the BESIII detector ...
Observation of the decays chi(cJ) -> phi phi eta
(Amer Physical Soc., 2020)
Using a data sample of (448.1 +/- 2.9) x 10( )(6)psi(3686) decays collected by the BESIII detector at the Beijing Electron Positron Collider (BEPCII), we observe the decays chi(cJ) -> phi phi eta (J = 0, 1, 2), where the ...
Observation of the Y(4220) and Y(4390) in the process e(+)e(-) -> eta J/psi
(Amer Physical Soc., 2020)
The cross sections of the process e(+)e(-) -> eta J/psi lip at center-of-mass energies (root s) between 3.81 and 4.60 GeV are measured with high precision by using data samples collected with the BESIII detector operating ...
Improved model-independent determination of the strong-phase difference between D-0 and (D)over-bar(0) -> (KS,LK+)-K-0 K- decays
(Amer Physical Soc., 2020)
We present a measurement of the strong-phase difference between D-0 and (D) over bar (0) -> (KS,LK+K-)-K-0 decays, performed through a study of quantum-entangled pairs of charm mesons. The measurement exploits a data sample ...
Determination of Strong-Phase Parameters in D -> K-S,L(0)pi(+)pi(-)
(Amer Physical Soc., 2020)
We report the most precise measurements to date of the strong-phase parameters between D-0 and (D) over bar (0) decays to K-S,L(0)pi(+)pi(-) using a sample of 2.93 fb(-1) of e(+) e(-) annihilation data collected at a ...
Search for the semileptonic decay D0(+) -> b(1) (1235)(-(0))e(+)v(e)
(Physical Review D., 2020)
Using 2.93 fb-1 of e(+)e(-) data collected at a center-of-mass energy root s = 3.773 GeV with the BESIII detector operating at the BEPCII collider, we search for the semileptonic D0(+) decays into a b(1)(1235)(-(0)) ...
Partial wave analysis of psi(3686) -> K+ K- eta
(Amer Physical Soc., 2020)
Using a sample of (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the BESIII detector, we perform the first partial wave analysis of psi(3686) -> K+K- eta. In addition to the well established states, phi(1020), ...
Study of Open-Charm Decays and Radiative Transitions of the X(3872)

The processes X(3872) -> D*(0)(D) over bar (0) + c.c., gamma J/psi, gamma psi(2S), and gamma D+D- are searched for in a 9.0 fb(-1) data sample collected at center-of-mass energies between 4.178 and 4.278 GeV with the BESIII ...
Inclusive charged and neutral particle multiplicity distributions in chi(cJ) and J/psi decays
(Amer Physical Soc., 2020)
Using a sample of 106 million psi(3686) decays, psi(3686) -> gamma chi(cJ) (J = 0, 1, 2) and psi(3686) -> gamma chi(cJ), chi(cJ) -> gamma J/psi (J = 1, 2) events are utilized to study inclusive chi(cJ )-> anything, chi(cJ ...
