| Abstract | The double differential cross sections of the Drell-Yan lepton pair ($\ell^+\ell^-$, electron or muon) production, as a function of its invariant mass $m_{\ell\ell}$, transverse momentum $p_\mathrm{T}(\ell\ell)$, and $\varphi^*$ are measured. The $\varphi^*$ observable is highly correlated with $p_\mathrm{T}(\ell\ell)$ and is used to probe the low $p_\mathrm{T}(\ell\ell)$ region in a complementary way. Drell-Yan masses up to $1~\mathrm{TeV}$ are investigated. Additionally, a measurement is performed requiring at least one jet in the final state. To benefit from partial cancellation of the systematic uncertainty, the ratios of the differential cross sections in $p_\mathrm{T}(\ell\ell)$ and $\varphi^*$ for the $m_{\ell\ell}$ bins around the $Z$ mass peak over the one on the $Z$ mass peak are presented. The collected data correspond to an integrated luminosity of $36.3~\mathrm{fb}^{-1}$ of proton-proton collisions recorded with the CMS detector at the LHC at the center-of-mass energy of $13~\mathrm{TeV}$ in 2016. Measurements are compared to state-of-the-art predictions based on perturbative quantum chromodynamics including soft gluon resummation. |
