| Abstract: The fragmentation function of inclusive jets in the pPb collision at $\sqrt{s_{\mathrm{NN}}} =$ 5.02 TeV is studied, with a dataset corresponding to an integrated luminosity of 31 nb$^{-1}$. In order to study possible nuclear effects in jet production, this is compared to an pp reference constructed based on the $\sqrt{s} =$ 2.76 TeV and $\sqrt{s} =$ 7 TeV data, where the fragmentation function is adjusted to the expected flavor mixture at $\sqrt{s} =$ 5.02 TeV. The measured pPb fragmentation is found to be consistent with the pp, within the current statistical and systematic uncertainty. This analysis also represents the first CMS measurement of jet fragmentation function at $\sqrt{s} =$ 7TeV, and updates the $\sqrt{s} =$ 2.76 TeV jet fragmentation function using pp track and jet reconstruction. | ||
