Differential cross sections, charge production asymmetry, and spin-density matrix elements for D*(2010) produced in 500 GeV/c pi- nucleon interactions
Fermilab E791 Collaboration
Abstract
We report differential cross sections for the production of D*(2010) produced in 500 GeV/c pi- nucleon interactions from experiment E791 at Fermilab, as functions of Feynman-x (xF) 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.
