@article{10902/18204, year = {2019}, month = {6}, url = {http://hdl.handle.net/10902/18204}, abstract = {An embedding technique is presented to estimate standard model ττ backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed μμ events and replaced with simulated tau leptons with the same kinematic properties. In this way, a set of hybrid events is obtained that does not rely on simulation except for the decay of the tau leptons. The challenges in describing the underlying event or the production of associated jets in the simulation are avoided. The technique described in this paper was developed for CMS. Its validation and the inherent uncertainties are also discussed. The demonstration of the performance of the technique is based on a sample of proton-proton collisions collected by CMS in 2017 at √s=13 TeV corresponding to an integrated luminosity of 41.5 fb−1.}, publisher = {Institute of Physics}, publisher = {JINST 14 P06032 (2019)}, title = {An embedding technique to determine ꚍꚍ backgrounds in proton-proton collision data}, author = {Sirunyan, A.
