Query: Precision studies of vector-boson production with heavy quarks at the
  LHC: the case of Z+b jet   After a brief introduction to the state of the art of theoretical predictions
for electroweak vector-boson production with both top and bottom quarks at the
LHC, we review the case of Z-boson production with b jets, and discuss the
impact of NLO QCD+EW corrections and finite b-quark mass effects on the
theoretical prediction for Z+b jet production.
