Query: Top quark production   We review the current status of the cross sections measurement of the
top-quark at the LHC and at the Tevatron. Total production cross sections,
studies using single top quark events and differential $\rm{t}\bar{\rm t}$
cross sections are discussed. The associated production of top quark pairs with
photons, Z and W bosons, including $\rm{t}\bar{\rm t}$Z and $\rm{t}\bar{\rm
t}$W measurements shown for the first time at LHCP2014, are presented.
