Measurements of the associated production of a Z boson with at least one jet originating from a b quark in proton-proton collisions at sqrt(s) = 8 TeV are presented. Differential cross sections are measured with data collected by the CMS experiment corresponding to an integrated luminosity of 19.8 inverse femtobarns. Z bosons are reconstructed through their decays to electrons and muons. Cross sections are measured as a function of observables characterizing the kinematics of the b jet and the Z boson. Ratios of differential cross sections for the associated production with at least one b jet to the associated production with any jet are also presented. The production of a Z boson with two b jets is investigated, and differential cross sections are measured for the dijet system. Results are compared to theoretical predictions, testing two different flavour schemes for the choice of initial-state partons.

Search for dark matter produced in association with one or two top quarks in proton-proton collisions at $\sqrt{s}$ = 13 TeV
A search for dark matter produced with one or two top quarks finds no significant signal and excludes scalar and pseudoscalar mediator masses below 310 and 320 GeV at 95% confidence.

Search for flavour-changing neutral currents in processes with one top quark and a photon using 81 fb$^{-1}$ of $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS experiment
ATLAS finds no evidence for tqγ flavour-changing neutral currents and sets the most stringent limits to date on the associated production cross sections and branching ratios.
