The algorithm exploits the correlation of the flavour of a B meson with the charge of a reconstructed secondary charm hadron from the decay of the other b hadron produced in the proton-proton collision. Charm hadron candidates are identified in a number of fully or partially reconstructed Cabibbo-favoured decay modes. The algorithm is calibrated on the self-tagged decay modes B+ -> J/psi K+ and B-0 -> J/psi K*(0) using 3.0fb(-1) of data collected by the LHCb experiment at pp centre-of-mass energies of 7TeV and 8TeV. Its tagging power on these samples of B -> J/psi X decays is (0.30 +/- 0.01 +/- 0.01) {\%}.", optnote="WOS:000367674700007", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=2519), last updated on Thu, 28 Jan 2016 16:46:24 +0000", issn="1748-0221", doi="10.1088/1748-0221/10/10/P10005", opturl="http://arxiv.org/abs/1507.07892", opturl="https://doi.org/10.1088/1748-0221/10/10/P10005", archivePrefix="arXiv", eprint="1507.07892", language="English" }
