چکیده

The contribution of B meson decays to nonphotonic electrons, which are mainly produced by the semileptonic decays of heavy-flavor mesons, in p + p collisions at √s=200  GeV has been measured using azimuthal correlations between nonphotonic electrons and hadrons. The extracted B decay contribution is approximately 50% at a transverse momentum of pT≥5  GeV/c. These measurements constrain the nuclear modification factor for electrons from B and D meson decays. The result indicates that B meson production in heavy ion collisions is also suppressed at high pT.

Nuclear modification factor of nonphotonic electrons in heavy-ion collisions, and the heavy-flavor baryon-to-meson ratio

The nuclear modification factor RAA of nonphotonic electrons in Au + Au collisions at √sNN = 200 GeV is studied by considering the decays of heavy-flavor hadrons produced in a quark coalescence model. Although an enhanced c/D ratio is predicted by the coalescence model, it is peaked at small transverse momenta (∼2 GeV) due to the large difference between heavy and light quark masses. As a resul...

We investigate the effect of the so-called anomalous baryon/meson enhancement to the nuclear modification factor of non-photonic electrons in Au+Au collisions at √ sNN = 200 GeV. It is demonstrated that an enhancement of the charm baryon/meson ratio, as it is observed for non-strange and strange hadrons, can be responsible for part of the amplitude of the nuclear modification factor of non-phot...

Electrons and Heavy Quark at PHENIX Detector

Measurement of heavy quark production is one of the tools used to investigate the matter produced in extremely hot and dense conditions in heavy ion collisions at RHIC. The PHENIX experiment has measured mid-rapidity transverse momentum spectra of electrons. After subtracting the photonic background contribution, the electron spectra are mainly due to semileptonic decays of hadrons containing h...

Azimuthal Correlations between Non-Photonic Electrons and Charged Hadrons in p+p Collisions from STAR

We present the preliminary measurement of azimuthal correlations between nonphotonic electrons and charged hadrons in p+p collisions at √ sNN = 200 GeV from STAR. The results are compared to PYTHIA simulations to estimate the relative contributions of D and B meson semi-leptonic decays to the non-photonic electrons.
