Precision measurement of the integrated luminosity of the data taken by BESIII at center-of-mass energies between 3.810 GeV and 4.600 GeV
(Institute of Physics Publishing, 2015)
From December 2011 to May 2014, about 5 fb-1 of data were taken with the BESIII detector at center-of-mass energies between 3.810 GeV and 4.600 GeV to study the charmonium-like states and higher excited charmonium states. ...
Measurement of the e+e- ??J /? cross section and search for e+e- ??0J /? at center-of-mass energies between 3.810 and 4.600 GeV
(American Physical Society, 2015)
Using data samples collected with the BESIII detector operating at the BEPCII collider at 17 center-of-mass energies from 3.810 to 4.600 GeV, we perform a study of e+e-??J/? and ?0J/?. The Born cross sections of these two ...
Measurements of cross section of e+e??pp¯?0 at center-of-mass energies between 4.008 and 4.600 GeV
(Elsevier B.V., 2017)
Based on e+e? annihilation data samples collected with the BESIII detector at the BEPCII collider at 13 center-of-mass energies from 4.008 to 4.600 GeV, measurements of the Born cross section of e+e??pp¯?0 are performed. ...
Measurement of yCP in D0-D0 oscillation using quantum correlations in e+e- ? D0D0 at ?s = 3.773 GeV
(Elsevier B.V., 2015)
We report a measurement of the parameter yCP in D0-D-0 oscillations performed by taking advantage of quantum coherence between pairs of D0D-0 mesons produced in e+e- annihilations near threshold. In this work, doubly-tagged ...
Measurement of cross sections of the interactions e(+)e(-) -> phi phi omega and e(+)e(-) -> phi phi phi at center-of-mass energies from 4.008 to 4.600 GeV
(Elsevier Science, 2017)
Using data samples collected with the BESIII detector at the BEPCII collider at six center-of-mass energies between 4.008 and 4.600 GeV, we observe the processes e(+)e(-) -> phi phi omega and e(-)e(-) -> phi phi phi. The ...
Confirmation of a charged charmoniumlike state Zc (3885)? in e+e- ??± (D D ¯ ?)? with double D tag
(American Physical Society, 2015)
We present a study of the process e+e-??±(DD¯?)? using data samples of 1092 pb-1 at s=4.23 GeV and 826 pb-1 at s=4.26 GeV collected with the BESIII detector at the BEPCII storage ring. With full reconstruction of the D ...
Human papillomavirus prevalence and genotype distribution among Turkish women with or without cervical lesion
(Wolters Kluwer Medknow Publications, 2018)
Context: Human papillomavirus (HPV) infection is the main cause of cervical cancer, but the risk is associated with the various HPV genotypes which may be found in women with or without clinical findings. Aims: We aimed ...
Improved measurements of branching fractions for eta(c) -> phi phi and omega phi
(Amer Physical Soc., 2017)
Using (223.7 +/- 1.4) x 10(6) J / Psi events accumulated with the BESIII detector, we study eta(c) decays to phi phi and omega phi final states. The branching fraction of n(c) -> phi phi is measured to be Br(eta(c) -> phi ...
Observation of a cross-section enhancement near mass threshold in e(+)e(-) -> Lambda(Lambda)over-bar
(Amer Physical Soc., 2019)
The process e(+)e(-) -> Lambda(Lambda) over bar is studied using data samples at root s = 2.2324, 2.400, 2.800 and 3.080 GeV collected with the BESIII detector operating at the BEPCII collider. The Born cross section is ...
Measurement of the matrix elements for the decays eta' -> eta pi(+) pi(-) and eta' -> eta pi(0)pi(0)
(Amer Physical Soc., 2018)
Based on a sample of 1.31 x 10(9) J/psi events collected with the BESIII detector, the matrix elements for the decays eta' -> eta pi(+) pi(-) and eta' -> eta pi(0)pi(0) are determined using 351,016 eta' -> (eta -> gamma ...
