AbstractWe present the STAR preliminary results of non-photonic electron and charged hadron azimuthal correlation at midrapidity at 6.5 < p(T)(NPE) < 12.5 GeV/c in 500 GeV p+p collisions. The correlation distributions are compared with PYTHIA simulations to extract the relative contribution of B mesons to non-photonic electrons. Our measurements indicate that the extracted B meson decay contribution is above 60% at 8.5 < p(T) < 12.5 GeV/c. By comparing the results between 200 and 500 GeV energies, we find that e(B)/(e(B) + e(D)) ratio is higher at 500 GeV than 200 GeV at 6.5 < p(T) < 9.5 GeV/c.
