Abstract
We report differential cross sections for the production of D*±(2010) produced in 500 GeV/c π--nucleon interactions from experiment E791 at Fermilab, as functions of Feynman-χ (χF) and transverse momentum squared (pT2). We also report the D*± charge asymmetry and spin-density matrix elements as functions of these variables. Investigation of the spin-density matrix elements shows no evidence of polarization. The average values of the spin alignment are (η) = 0.01 ± 0.02 and -0.01 ± 0.02 for leading and non-leading particles, respectively. © 2002 Elsevier Science B.V. All rights reserved.
