Query: On the Character of Leading Asymmetry in the Hadroproduction of Charmed
  Mesons and Baryons   The character of asymmetry between the spectra of Lambda_c and antiLambda_c
in the E781 experiment (FNAL) is discussed on the basis of the Quark Gluon
String Model(QGSM). As it was shown in the description of the asymmetry between
the spectra of leading and nonleading charmed mesons measured in Sigma^--A
interactions at p_L= 340 GeV/c in the WA89 experiment in previous studies, the
asymmetries between D^- and D^+ meson spectra and between D_s^- and D^+_s meson
spectra can be fitted by QGSM curves with the same parameter of string
fragmentation, a_1=10, as well as the asymmetry between the D-meson spectra in
pion-nuclear collisions in the E791 experiment. The forms of
Lambda_c/antiLambda_c asymmetry dependences measured in Sigma^-A and p-A
collisions at p_L= 600 GeV/c in the E781 experiment are different . It is shown
in the framework of QGSM that they depend on whether the diquarks of beam and
target particles took part in charmed baryon formation or not. The QGSM results
are compared with the calculations carried out by the other authors.
