Add   Measurement of the branching fractions of Ds+→η'X and Ds+→η'ρ+ in e+e-→Ds+Ds-
Authors: Ablikim, M. | Ai, X. C. | Chelkov, G. A. | Achasov, M. N.
Source: Physics Letters B. 2015. Vol. 750. P. 466-474
Type: статьи в журналах
Date: 2015
Description: We study D+s decays to final states involving the η with a 482 pb−1 data sample collected at √s = 4.009 GeV with the BESIII detector at the BEPCII collider. We measure the branching fractionsB(D+s →η ... More
Add   Observation of the Dalitz decay η' → γe+e-
Authors: Ablikim, M. | Ai, X. C. | Chelkov, G. A. | Achasov, M. N.
Source: Physical Review D. 2015. Vol. 92, № 1. P. 012001-1-012001-11
Type: статьи в журналах
Date: 2015
Description: We report the first observation of the Dalitz decay η′→γe+e−, based on a data sample of 1.31 billion J/ψ events collected with the BESIII detector. The η′ mesons are produced via the J/ψ→γη′ decay pro ... More
Add   Observation of an excited Bc± meson state with the ATLAS detector
Authors: Aad, G. | Abdallah, J. | Chelkov, G. A. | Abbott, B.
Source: Physical Review Letters. 2014. Vol. 113, № 21. P. 212004-1-212004-18
Type: статьи в журналах
Date: 2014
Description: A search for excited states of the Bf meson is performed using 4.9 fb-1 of 7 TeVand 19.2 fb-1 of 8 TeV pp collision data collected by the ATLAS experiment at the LHC. A new state is observed through i ... More
