/\_c+ - /\_c- production asymmetries in two component models
J. Magnin, L. M. Mendoza-Navas
Experiments on charm hadroproduction have shown a substantial difference in the production of charm and anticharm hadrons. In this work we study /\_c+ and /\_c- inclusive productio…
Charge Asymmetries in charm photoproduction
E. Cuautle, G. Herrera, J. Magnin +1
Charm quarks are expected to be produced mainly by the photon-gluon fusion mechanism in photon-Nucleon interactions. However, a small part of the total charm cross section originat…
Hadronic fluctuations and quark-antiquark asymmetry in the nucleon
H. R. Christiansen, J. Magnin
We derive the nucleon non-perturbative sea-quark distributions coming from a composite model involving quarks and hadronic degrees of freedom. The model predicts a definite structu…
Hyperon production asymmetries in 500 GeV/c pion nucleus interactions
J. Solano, J. Magnin, F. R. A. Simao +1
We present a preliminary study from Fermilab experiment E791 of Lambda^0 / Lambda^0 bar, Xi^- / Xi^+ and Omega^- /Omega^+ production asymmetries from pi^- nucleus interactions at 5…
