LHCb Collaboration; Anderson, J; Bernet, R; Chiapolini, N; De Cian, M; Palacios, J; Salzmann, C; Serra, N; Steinkamp, O; Straumann, U; Vollhardt, A (2012). Measurement of the effective B0s →K+K− lifetime. Physics Letters B, 707(3-4):349-356.

## Abstract

A measurement of the effective B0s → K+K− lifetime is presented using approximately 37 pb−1 of data collected by LHCb during 2010. This quantity can be used to put constraints on contributions from processes beyond the Standard Model in the B0s meson system and is determined by two complementary approaches as τK K = 1.440±0.096 (stat)± 0.008 (syst)± 0.003 (model) ps.

## 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.
