Description
Heavy flavor quarks are an important probe of the initial state of the Quark Gluon Plasma formed in heavy-ion collisions.
Bottom and charm quarks are produced early in the collision, primarily through hard interactions, and experience the full time evolution of the medium.
Understanding bottom quark production in $p+p$ collisions gives a baseline reference for studying larger collision systems.
The measurement of the $b\bar{b}$ cross section gives insight into $b$ quark production mechanisms which can directly test pQCD predictions.
The $b\bar{b}$ signal can be isolated by taking advantage of the properties of $B^{0}$ oscillations in the invariant mass region of 4-10 GeV.
Measuring like-sign dimuons within this mass range provides an enriched bottom signal with a minimal amount of open charm background and without any contributions from quarkonia or Drell-Yan pairs.
$b\bar{b}$ will be measured through the semi-leptonic decay like-sign dimuon signal, in the rapidity range 1.2 $<|y|< $ 2.2 and at $\sqrt{s} = 510$ GeV from data recorded in 2013 at the PHENIX experiment.
In this poster, the status of the $b\bar{b}$ production study will be presented.
