"Measuring high pT single electrons from open heavy flavor in pp collisions at s=200GeV using the PHENIX detector"

Presented by Harry Themann, Stony Brook University

Thursday, July 7, 2011, 3:00 pm — Small Seminar Room, Bldg. 510

Transverse momentum (pT ) spectra of electrons from semileptonic weak decays of heavy flavor mesons in the range of 0.3 < pT < 15.0 GeV/c have been measured at midrapidity (|y| < 0.35) beyond the previous published range of pT < 9.0 GeV/c. This is done using a new technique exploiting the observed characteristics of energy deposition in the PHENIX electromagnetic calorimeters. We present this technique as well as the final measurement compared to FONLL theory predictions of “open” charm and bottom cross section.
