Abstract We study the production of an electroweak boson in association with jets, processes where jet highest transverse momentum is identified as quark-initiated. The quark/gluon tagging procedure realised by a cut on angularity and it therefore theoretically well-defined exhibits infrared collinear safety. In this context, exploiting resummed perturbation theory, we are able to provide theor...

Abstract The identification of charm jets is achieved at LHCb for data collected in 2015–2018 using a method based on the properties displaced vertices reconstructed and matched with jets. performance this determined dijet calibration dataset recorded by detector selected such that are unbiased quantities used tagging algorithm. charm-tagging efficiency reported as function transverse momentum ...

In this paper, we transform the issue of Chinese-English tense conversion into the issue of tagging a Chinese tense tree. And then we propose Markov Tree Tagging Model to tag nodes of the untagged tense tree with English tenses. Experimental results show that the method is much better than linear-based CRF tagging for the issue.
