Abstract


The incident quark energy loss effect is different from another nuclear effects of the nuclear effects in deep inelastic scattering in central molecule distribution function . Hadron - nucleus collisions the Drell-Yan process is the best process to study the effects of cold nuclear incident quark energy loss , nuclear Drell-Yan process through research studies , a better understanding of the incident quark in the the nuclear environment dissemination process energy loss . E772 and E866 experimental group reported 800GeV proton combat , Be , C, Ca , Fe , and W nuclei (A) for each of the two nuclei nuclear Drell-Yan reaction cross section ratio . The purpose of the two experimental groups differ , however, they obtained experimental data for us to study the energy loss of the incident quark in the the nuclear environment dissemination process provides an experimental basis . The article uses the the HKM bound nuclear central molecule distribution function , consider two different incident quark energy loss parameter type to seek call CERNLIB the MINUIT χ2 optimization , respectively processing of the experimental data of the E772 and E866 . E772 and E866 experimental data overall analysis , we get the parameters and their theoretical uncertainty in two different incident quark energy loss expression were
