Source: Physical Review D. 2017. Vol. 96, № 1. P. 012005-1-012005-8
Type: статьи в журналах
Date: 2017
Description: Based on a sample of 1.31 billion J/ψ events collected with the BESIII detector, we report the study of the doubly radiative decay η′→γγπ0 for the first time, where the η′ meson is produced via the J/ ... More

Date: 2017
Description: We report the first direct measurement of decays of the Λ+c baryon involving the neutron. The analysis is performed using 567  pb−1 of e+e− collision data collected at √s=4.599  GeV with the BESIII de ... More

Type: статьи в журналах
Date: 2016
Description: Using 1.09×109 J/ψ events collected by the BESIII experiment in 2012, we study the J/ψ→γη′π+π− process and observe a significant abrupt change in the slope of the η′π+π− invariant mass distribution at ... More
