Description
PHENIX has measured the $b\overline{b}$ production cross section in
$p$$+$$p$ collisions at $\sqrt{s} = 500$~GeV. In the absence of
displaced-vertex $b$-tagging, this is made possible by exploiting
the properties of $B^{0}-\overline{B^{0}}$ oscillations. Like-sign
muon pairs in the PHENIX muon arms are measured in order to extract
this signal. We report the $b\overline{b}$ differential cross
section in the rapidity range $1.2 < |y| < 2.2$, for dimuon masses
in the range 5--10~GeV/$c^2$, and extrapolate to the total-production
cross section.
