Observations of B0s→ψ(2S)η and B0(s)→ψ(2S)π+π− decays


LHCb Collaboration; et al; Bernet, R; Müller, K; Steinkamp, O; Straumann, U; Vollhardt, A (2013). Observations of B0s→ψ(2S)η and B0(s)→ψ(2S)π+π− decays. Nuclear Physics B - Proceedings Supplements, 871(3):403-419.

Abstract

First observations of the B0s→ψ(2S)η, B0→ψ(2S)π+π− and B0s→ψ(2S)π+π− decays are made using a dataset corresponding to an integrated luminosity of 1.0fb−1 collected by the LHCb experiment in proton–proton collisions at a centre-of-mass energy of s√=7TeV. The ratios of the branching fractions of each of the ψ(2S) modes with respect to the corresponding J/ψ decays are
B(B0s→ψ(2S)η)B(B0s→J/ψη) =0.83±0.14(stat)±0.12(syst)±0.02(B),
B(B0→ψ(2S)π+π−)B(B0→J/ψπ+π−) =0.56±0.07(stat)±0.05(syst)±0.01(B),
B(B0s→ψ(2S)π+π−)B(B0s→J/ψπ+π−)=0.34±0.04(stat)±0.03(syst)±0.01(B),
where the third uncertainty corresponds to the uncertainties of the dilepton branching fractions of the J/ψ and ψ(2S) meson decays.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
