Type: статьи в журналах
Date: 2018
Description: An amplitude analysis of the KSKS system produced in radiative J/ψ decays is performed using the (1310.6±7.0)×106  J/ψ decays collected by the BESIII detector. Two approaches are presented. A mass-dep ... More

Type: статьи в журналах
Date: 2017
Description: Using 2.93  fb−1 of data taken at 3.773 GeV with the BESIII detector operated at the BEPCII collider, we study the semileptonic decays D+→¯K0e+νe and D+→π0e+νe. We measure the absolute decay branching ... More

Type: статьи в журналах
Date: 2017
Description: A measurement of the number of J/ψ events collected with the BESIII detector in 2009 and 2012 is performed using inclusive decays of the J/ψ. The number of J/ψ events taken in 2009 is recalculated to ... More

Type: статьи в журналах
Date: 2017
Description: We present first evidence for the process e+e−→γηc(1S) at six center-of-mass energies between 4.01 and 4.60 GeV using data collected by the BESIII experiment operating at BEPCII. We measure the Born c ... More

Date: 2017
Description: Using a data sample of 448×106  ψ(3686) events collected with the BESIII detector operating at the BEPCII storage ring, the decays ψ(3686)→γη and ψ(3686)→γπ0 are observed with a statistical significan ... More

Type: статьи в журналах
Date: 2017
Description: To study the nature of the state Y (2175), a dedicated data set of e+e− collision data was collected at the center-of-mass energy of 2.125 GeV with the BESIII detector at the BEPCII collider. By analy ... More

Type: статьи в журналах
Date: 2017
Description: We report the first observation of the decay Λc+→Σ−π+π+π0, based on data obtained in e+e− annihilations with an integrated luminosity of 567 pb−1 at s=4.6GeV. The data were collected with the BESIII d ... More

Type: статьи в журналах
Date: 2016
Description: Based on 2.93  fb−1 e+e− collision data taken at center-of-mass energy of 3.773 GeV by the BESIII detector, we report searches for the singly Cabibbo-suppressed decays D+→ωπ+ and D0→ωπ0. A double tag ... More

Date: 2015
Description: Using data samples collected at center-of-mass energies of √s=4.009, 4.230, 4.260, and 4.360 GeV with the BESIII detector operating at the BEPCII collider, we perform a search for the process e+e−→γχc ... More

Type: статьи в журналах
Date: 2015
Description: We report a study of the process e+e−→(D∗D¯∗)0π0 using e+e− collision data samples with integrated luminosities of 1092  pb−1 at s√=4.23  GeV and 826  pb−1 at s√=4.26  GeV collected with the BESIII de ... More
