Measurement of the effective B0s→K+K− lifetime

Article history: Received 2 November 2011 Received in revised form 20 December 2011 Accepted 22 December 2011 Available online 28 December 2011 Editor: W.-D. Schlatter A measurement of the effective Bs → 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 Mo...

v 1 1 N ov 1 99 6 HU - SEFT R 1996 - 21 October 31 , 1996 ATLAS sensitivity range for the x s measurement

Previous results for the prospects of B0s mixing measurement in the ATLAS experiment at LHC are updated. The improved analysis method of the studied decay channels B0s → D − s π + and B0s → D − s a + 1 , combined with most recent values for the branching ratios and the B0s lifetime, leads to the new ATLAS sensitivity range for the xs measurement: x max s = 42. An extensive study is done in orde...

Measurement of the effective B0s→J/ψK0S lifetime

This paper reports the first measurement of the effective B0 s → J/ψK0 S lifetime and an updated measurement of its time-integrated branching fraction. Both measurements are performed with a data sample, corresponding to an integrated luminosity of 1.0 fb−1 of pp collisions, recorded by the LHCb experiment in 2011 at a centre-of-mass energy of 7 TeV. The results are: τ eff J/ψK0 S = 1.75 ± 0.12...

Integrating AHP and data mining for effective retailer segmentation based on retailer lifetime value

Data mining techniques have been used widely in the area of customer relationship management (CRM). In this study, we have applied data mining techniques to address a problem in business-to-business (B2B) setting. In a manufacturer-retailer-consumer chain, a manufacturer should improve its relationship with retailers to continue its business. Segmentation is a useful tool for identifying groups...
