  We study the precision with which the t-channel single top quark production
cross section is expected to be measured in future LHC runs at 14 TeV. The
single top final state has a lepton and neutrino from the top quark decay plus
two jets, one of which is required to be b-tagged. This measurement is done in
the context of the Snowmass 2013 study for the low-luminosity 14 TeV and the
high-luminosity 14 TeV LHC as well as for high-luminosity 33 TeV LHC.
