Photon + Heavy Flavor Jet Production at D0

A measurement of photon + b jet production is presented using about 1 fb~$^{-1}$ of data collected by the D0 detector at the Tevatron p pbar collider at a center-of-mass energy of 1.96~TeV. Isolated photons are selected in the rapidity range of $0 < |y| < 1.0$ and the jets are selected using the D0 Midpoint Cone Algorithm in the rapidity ranges $0 < |y| < 0.8$ or $1.5 < |y| < 2.5$. The measurement is expected to help constrain the understanding of the b quark content of the proton.
