Associated Z boson production in the forward region

A measurement of the Z(→ μ−μ+)+jet production cross-section and an observation of associated production of a Z boson with a D meson in pp collisions at a centre-of-mass energy of √ s =7 TeV is presented. The measurements are based on an integrated luminosity of 1.0 fb−1, collected by the LHCb experiment. For Z+jet, the overall cross-section in a fiducial volume as well as normalised differential cross-sections are measured for jet transverse momentum thresholds of 10 and 20 GeV. For Z+D, overall cross-sections are measured for Z(→ μ−μ+)+D0 and Z(→ μ−μ+)+D+ production based on eleven candidates in total.
