Query: Search for Single-Top-Quark Production at the Tevatron   This article reports on recent searches for single-top-quark production by
the CDF and DO collaborations at the Tevatron. Neither two CDF analyses, using
data corresponding to 695 pb^-1 of integrated luminosity, nor a DO search based
on 370 pb^-1 of data can establish a signal for this standard model process.
These null results translate in upper limits on the cross section of 2.9 pb for
the t-channel production mode and 3.2 pb for the s-channel mode at the 95% C.L.
In addition, the DO collaboration has searched for non-standard model
production of single-top-quarks via a heavy W^prime boson. No signal of this
process is found resulting in lower mass limits of 610 GeV/c^2 for a
left-handed W^prime and 630 GeV/c^2 for a right-handed W^\prime boson.
