# metadata.dc.description.abstract[].value
A measurement of the mean life of the D0 meson is performed using real D0 -> K+ π-
decay data collected at LHCb and selected according to the decay's speci c features. First, the
selection algorithm is described. Then, the measurement of the mean life is optimized by changing
the acceptance range of the data according to three variables involved in the selection. The value
obtained for the mean life is compatible with the worldwide averaged value provided by the Particle
Data Group.
