First measurements of chi(cJ) -> Sigma(-)(Sigma)over-bar(+) (J=0,1,2) decays
(Amer Physical Soc., 2020)
We measured the branching fractions of the decays chi(cJ) -> Sigma(-)(Sigma) over bar (+) for the first time using the final states n (n) over bar pi(+)pi(-). The data sample exploited here is 448.1 x 10(6) psi(3686) events ...
Future Physics Programme of BESIII
(IOP Publishing, 2020)
There has recently been a dramatic renewal of interest in hadron spectroscopy and charm physics. This renaissance has been driven in part by the discovery of a plethora of charmonium-like XYZ states at BESIII and B factories, ...
Sigma(+) and (Sigma)over-bar(-) Polarization in the J/psi and psi(3686) Decays
(Amer Physical Soc., 2020)
From 1310.6 x 10(6) J/psi and 448.1 x 10(6) psi (3686) events collected with the BESIII experiment, we report the first observation of Sigma(+) and (Sigma) over bar (-) spin polarization in e(+)e(-) -> J/psi[psi(3686)] -> ...
Measurement of J/psi -> Xi(1530+)(-) (Xi)over-bar(+) and evidence for the radiative decay Xi(153)(-) -> gamma Xi(-)
(Amer Physical Soc., 2020)
The SU(3)-flavor violating decay J/psi -> Xi(1530)(-) (Xi) over bar (+) + c.c. is studied using (1310.6 +/- 7.0) x 10(6) J/psi events collected with the BESIII detector at BEPCII, and the branching fraction is measured to ...
Search for the decay J/psi -> gamma plus invisible
(Amer Physical Soc., 2020)
We search for J/psi radiative decays into a weakly interacting neutral particle, namely an invisible particle, using the J/psi produced through the process psi(3686) -> pi(+)pi(-) J/psi in a data sample of (448.1 +/- 2.9) ...
Search for intermediate resonances and dark gauge bosons in J/psi -> gamma pi(0)eta '
(Amer Physical Soc., 2020)
We report on an analysis of the decay J/psi -> gamma pi(0)eta' using a sample of o1310.6 +/- 7.0THORN x 10(6) J/psi events collected with the BESIII detector. We search for the CP-violating process eta c -> pi(0)eta' and ...
Study of e(+)e(-) -> D+D-pi(+)pi(-) at center-of-mass energies from 4.36 to 4.60 GeV
(Elsevier, 2020)
We report a study of the e(+)e(-) -> D+D-pi(+)pi(-) process using e(+)e(-) collision data samples with an integrated luminosity of 2.5 fb(-1) at center-of-mass energies from 4.36 to 4.60 GeV, collected with the BESIII ...
Cross section measurement of e(+) e(-) -> eta ' J/psi from root S=4.178 to 4.600 GeV
(Amer Physical Soc., 2020)
The cross section of the process e(+) e(-) -> eta ' J/ psi is measured at center-of-mass (c.m.) energies from root S = 4.178 to 4.600 GeV using data samples corresponding to a total integrated luminosity of 11 fb(-1) ...
Measurements of Absolute Branching Fractions of Fourteen Exclusive Hadronic D Decays to eta
(Amer Physical Soc., 2020)
Using 2.93 fb(-1) of e(+)e(-) collision data taken at a center-of-mass energy of 3.773 GeV with the BESIII detector, we report the first measurements of the absolute branching fractions of 14 hadronic D0(+) decays to ...
Model-independent determination of the relative strong-phase difference between D-0 and (D)over-bar(0) -> K-S,L(0)pi(+)pi(-) and its impact on the measurement of the CKM angle gamma/phi(3)
(Amer Physical Soc., 2020)
Crucial inputs for a variety of CP-violation studies can be determined through the analysis of pairs of quantum-entangled neutral D mesons, which are produced in the decay of the psi(3770) resonance. The relative strong-phase ...
