Regency (Hyatt) The production of charmed hadrons (D^{+}, D^{-}, D^{0}, \bar{D}^{0}, \Lambda_{c}^{+}, \bar{\Lambda}_{c}^{-}) in pp collision as a function of \sqrt{s}, x_{F}, p_{\perp} and p_{\perp}^{2} have been studied in the framework of the QGSJET model. The charmed hadrons are considered as the potential sources of prompt lepton's fluxes in cosmic rays. So in this context, the study of the charmed hadroproduction characteristics in pp collision under a sound physical model is particularly significant to cheek the reliability of the model prediction. The charmed hadroproduction cross sections or the charmed hadrons' average multiplicities in pp collision have been found to be relatively very small. The maximum production of all charmed hadrons take place with low values of x_{F}, p_{\perp} and p_{\perp}^{2} within a small range for all values of \sqrt{s} under study. The Charmed hadroproduction cross sections as a function of x_{F} and p_{\perp}^{2} are compared with the LEBC-EHS and LEBC-MPS experiments' data for D-mesons production in the low energy range. The agreement is quite satisfactory for the smaller values of p_{\perp}^{2} (< = 2 (GeV/c)) ^2). 1 http://www.icrc2007.unam.mx/ link http://www.icrc2007.unam.mx/ doc http://indico.nucleares.unam.mx/images/word.png word file ppt http://indico.nucleares.unam.mx/images/powerpoint.png powerpoint file pdf http://indico.nucleares.unam.mx/images/pdf_small.png pdf file odt http://indico.nucleares.unam.mx/images/writer.png writer file odp http://indico.nucleares.unam.mx/images/impress.png presentation file ods http://indico.nucleares.unam.mx/images/calc.png spreadsheet file other http://indico.nucleares.unam.mx/images/file_small.png unknown type file link http://indico.nucleares.unam.mx/images/link.png link
