Authors: Adlarson, P. | Bardan, W. | Bashkanov, M. | Bergmann, F. S. | Berłowski, M. | Bhatt, H. | Bondar, A. | Büscher, M. | Calén, H. | Augustyniak, W. | Ciepał, I. | Clement, H. | Czerwiński, E. | Demmich, K. | Engels, R. | Skorodko, T.
Source: Physics Letters B. 2017. Vol. 770. P. 418-425
Type: статьи в журналах
Date: 2017
Description: Using the production reactions and , the Dalitz plot distribution for the decay is studied with the WASA detector at COSY, based on a combined data sample of events. The Dalitz plot density is paramet ... More
Add   Measurement of the matrix elements for the decays η →π+π-π0 and η/η′ →π0π0π0
Authors: Ablikim, M. | Ai, X. C. | Chelkov, G. A. | Achasov, M. N.

Description: Based on a sample of 1.31×109 J/ψ events collected with the BESIII detector at the BEPCII collider, Dalitz plot analyses of selected 79,625 η→π+π−π0 events, 33,908 η→π0π0π0 events, and 1,888 η′→π0π0π0 ... 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
