Abstract
The calibration and performance of the oppositeside
flavour tagging algorithms used for the measurements
of time-dependent asymmetries at the LHCb experiment
are described. The algorithms have been developed using
simulated events and optimized and calibrated with
B+ → J/ψK+, B0 → J/ψK∗0 and B0 → D∗−μ+νμ decay
modes with 0.37 fb−1 of data collected in pp collisions
at √s = 7 TeV during the 2011 physics run. The oppositeside
tagging power is determined in the B+ → J/ψK+
channel to be (2.10 ± 0.08 ± 0.24) %, where the first uncertainty
is statistical and the second is systematic.
