Dependence of inclusive jet production on the anti-$k_{\mathrm{T}}$ distance parameter in pp collisions at $\sqrt{s}=$ 13 TeV

Abstract

The dependence of inclusive jet production in proton-proton collisions with a center-of-mass energy of 13 TeV on the distance parameter $R$ of the anti-$k_{\mathrm{T}}$ algorithm is studied using data corresponding to integrated luminosities up to 35.9 fb${}^{-1}$ collected by the CMS experiment in 2016. The ratios of the inclusive cross sections as functions of transverse momentum $p_{\mathrm{T}}$ and rapidity $y$, for $R$ in the range 0.1 to 1.2 to those using $R=$ 0.4 are presented in the region 84 $<$ $p_{\mathrm{T}}$ $<$ 1588 GeV and $|y|$ $<$ 2.0. The results are compared to calculations at leading and next-to-leading order in the strong coupling constant using different parton shower models. The variation of the ratio of cross sections with $R$ is well described by calculations including a parton shower model, but not by a leading-order quantum chromodynamics calculation including nonperturbative effects. The agreement between the data and the theoretical predictions for the ratios of cross sections is significantly improved when next-to-leading order calculations with nonperturbative effects are used.
