Abstract
A measurement of the effective B0
s → 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 B0
s meson system and is determined by two complementary
approaches as
τK K = 1.440 ± 0.096 (stat) ± 0.008 (syst) ± 0.003 (model) ps.
