Observation of the suppressed ADS modes B±→[π±K∓π+π−]DK± and B±→[π±K∓π+π−]Dπ±


LHCb Collaboration; et al; Bernet, R; Müller, K; Steinkamp, O; Straumann, U; Vollhardt, A (2013). Observation of the suppressed ADS modes B±→[π±K∓π+π−]DK± and B±→[π±K∓π+π−]Dπ±. Physics Letters B, 723(1-3):44-53.

Abstract

An analysis of B±→DK±B±→DK± and B±→Dπ±B±→Dπ± decays is presented where the D meson is reconstructed in the four-body final state K±π∓π+π−K±π∓π+π−. Using LHCb data corresponding to an integrated luminosity of 1.0fb−1, first observations are made of the suppressed ADS modes B±→[π±K∓π+π−]DK±B±→[π±K∓π+π−]DK± and B±→[π±K∓π+π−]Dπ±B±→[π±K∓π+π−]Dπ± with a significance of 5.1σ and greater than 10σ, respectively. Measurements of CP asymmetries and CP-conserving ratios of partial widths from this family of decays are also performed. The magnitude of the ratio between the suppressed and favoured B±→DK±B±→DK± amplitudes is determined to be rBK=0.097±0.011.

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.
