Add   Measurement of the absolute branching fraction for Λc+ → Λe+νe
Authors: Ablikim, M. | Ai, X. C. | Chelkov, G. A. | Achasov, M. N.
Source: Physical Review Letters. 2015. Vol. 115, № 22. P. 221805 (1-7)-
Type: статьи в журналах
Date: 2015
Description: We report the first measurement of the absolute branching fraction for Λ+c→Λe+νe. This measurement is based on 567  pb−1 of e+e− annihilation data produced at s√=4.599  GeV, which is just above the Λ+ ... More
Add   Evidence for in e+e- → γχc1,2 at center-of-mass energies from 4.009 to 4.360 GeV
Authors: Ablikim, M. | Ai, X. C. | Chelkov, G. A. | Achasov, M. N.
Source: Chinese physics C. 2015. Vol. 39, № 4. P. 041001-1-041001-9
Type: статьи в журналах
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
Add   Study of e+e- → ωχcJ at center of mass energies from 4.21 to 4.42 GeV
Authors: Ablikim, M. | Ai, X. C. | Chelkov, G. A. | Achasov, M. N.
Source: Physical Review Letters. 2015. Vol. 114, № 9. P. 092003-1-092003-7
Type: статьи в журналах
Date: 2015
Description: Based on data samples collected with the BESIII detector at the BEPCII collider at nine center of mass energies from 4.21 to 4.42 GeV, we search for the production of e+e−→ωχcJ (J=0, 1, 2). The proces ... More
