Measurement of the Z boson production in association with at least two b jets in pp collisions at $\sqrt{s}$ = 13 TeV with CMS

The cross sections for Z boson production in association with at least two b jets are measured as a function of various kinematic variables, using pp collisions at $\sqrt{s}$ = 13 TeV recorded by the CMS experiment, corresponding to an integrated luminosity of 137 $\textrm{fb}^{-1}$. Decays of the Z boson to electrons or muons are considered with leading (sub-leading) lepton transverse momentum $p_\textrm{T}$ $>$ 35 (25) GeV and pseudorapidity $\lvert \eta \rvert$ $<$ 2.4, and the invariant mass within 71 and 111 GeV. Jets are selected with $p_\textrm{T}$ $>$ 30 GeV and $\lvert \eta \rvert$ $<$ 2.4. The results are compared to various QCD calculations.
