Double $Q^2$ -rescaling model and the nuclear effect of the parton distribution functions
Abstract. In order to overcome the shortcoming of nonconservation of nuclear momentum existing in the original $Q^2$ -rescaling model (O $Q^2$ RM) and avoid introducing nuclear shadowing factor, we proposed a double $Q^2$ -rescaling model (D $Q^2$ RM) for the parton distributions of the bound nucleo...

Double $Q^2$ -rescaling model and the nuclear effect of the parton distribution functions |
| abstract |
Abstract. In order to overcome the shortcoming of nonconservation of nuclear momentum existing in the original $Q^2$ -rescaling model (O $Q^2$ RM) and avoid introducing nuclear shadowing factor, we proposed a double $Q^2$ -rescaling model (D $Q^2$ RM) for the parton distributions of the bound nucleon. Using the experimental data of lepton-nucleus deep inelastic scattering (DIS) and the condition of the nuclear momentum conservation, the $Q^2$ -rescaling parameters of various partons for Sn, Fe, Ca and C nuclei are determined. The rescaling parameters of valence quark distributions are larger than unity and gradually increase with atomic number A, on the contrary, the rescaling parameters of sea quark distributions and gluon distributions are smaller than unity, and slowly decrease with A. By using this model, the experimental data of the DIS process, the nuclear Drell-Yan process and $J/\psi$ ph otoproduction process are consistently and quite satisfactorily explained. |

In order to overcome the shortcoming of nonconservation of nuclear momentum existing in the original $Q^2$ -rescaling model (O $Q^2$ RM) and avoid introducing nuclear shadowing factor, we proposed a double $Q^2$ -rescaling model (D $Q^2$ RM) for the parton distributions of the bound nucleon. Using the experimental data of lepton-nucleus deep inelastic scattering (DIS) and the condition of the nuclear momentum conservation, the $Q^2$ -rescaling parameters of various partons for Sn, Fe, Ca and C nuclei are determined. The rescaling parameters of valence quark distributions are larger than unity and gradually increase with atomic number A, on the contrary, the rescaling parameters of sea quark distributions and gluon distributions are smaller than unity, and slowly decrease with A. By using this model, the experimental data of the DIS process, the nuclear Drell-Yan process and $J/\psi$ ph otoproduction process are consistently and quite satisfactorily explained.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Springer Online Journal Archives 1860-2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">He, Zhenmin</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yao, Xiaoxia</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Duan, Chungui</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Li, Guanglie</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Peng, Hongan</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">The European physical journal</subfield><subfield code="d">1998</subfield><subfield code="g">4(1998) vom: Feb., Seite 301-306</subfield><subfield code="w">(DE-627)NLEJ188986553</subfield><subfield code="w">(DE-600)1459069-4</subfield><subfield code="x">1434-6052</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:4</subfield><subfield code="g">year:1998</subfield><subfield code="g">month:02</subfield><subfield code="g">pages:301-306</subfield><subfield code="g">extent:6</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://dx.doi.org/10.1007/s100529800756</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SOJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">4</subfield><subfield code="j">1998</subfield><subfield code="c">2</subfield><subfield code="h">301-306</subfield><subfield code="g">6</subfield></datafield></record></collection>
