Measurement of inclusive electrons from open heavy-flavor hadron decays in p + p collisions at √s=200 GeV with the STAR detector
We report a new measurement of the production cross section for inclusive electrons from open heavy-flavor hadron decays as a function of transverse momentum (pT) at midrapidity (|y|<0.7) in p+p collisions at √s=200 GeV. The result is presented for 2.5<pT<10 GeV/c with an improved precision...

| Zusammenfassung: | We report a new measurement of the production cross section for inclusive electrons from open heavy-flavor hadron decays as a function of transverse momentum (pT) at midrapidity (|y|<0.7) in p+p collisions at √s=200 GeV. The result is presented for 2.5<pT<10 GeV/c with an improved precision above 6 GeV/c with respect to the previous measurements, providing more constraints on perturbative QCD calculations. Moreover, this measurement also provides a high-precision reference for measurements of nuclear modification factors for inclusive electrons from open-charm and -bottom hadron decays in heavy-ion collisions. |
