Charm quark and meson production in association with single-jet at the LHC

Abstract

We discuss charm quark/antiquark and charmed meson production in association with one extra jet (gluon, quark, antiquark) at the LHC. The calculations are performed both in collinear and $k_T$-factorization approaches. Different unintegrated gluon distribution functions are used in the $k_T$-factorization approach. Several predictions for the LHC are presented. We show distributions in rapidity and transverse momenta of $c$/$\bar{c}$ (or charmed mesons) and the associated jet as well as some two-dimensional observables. Interesting correlation effects are predicted, \textit{e.g.} in azimuthal angles ${\phi }_{c\bar{c}}$ and ${\phi }_{c\text{-jet}}$. We have also discussed a relation of the $2\to 2$ and $2\to 3$ partonic calculations in the region of large transverse momenta of charm quarks/antiquarks as well as the similarity of the next-to-leading order collinear approach and the $k_T$-factorization approach with the KMR unintegrated parton distribution functions. Integrated cross sections for $D^0$ + jet production for ATLAS detector acceptance and for different cuts on jet transverse momenta are also presented.
