高能开粲产生与夸克Regge化假说

Open charm production at high energies and the quark Reggeization hypothesis

B. A. Kniehl, A. V. Shipilova, V. A. Saleev

摘要:

我们在准多Regge运动学方法的框架下,应用Reggeon-Reggeon-particle和Reggeon-particle-particle有效顶点实现的夸克Reggeization假设,研究了高能下的开粲产生.采用Kimber-Martin-Ryskin非积分的质子和光子的夸克和胶子分布函数,我们很好地描述了DESY HERA测量的质子结构函数F_{2,c}以及HERA光生和费米实验室Tevatron强子产生的D介子的横动量分布.

英文摘要:

We study open charm production at high energies in the framework of the quasi-multi-Regge-kinematics approach applying the quark-Reggeization hypothesis implemented with Reggeon-Reggeon-particle and Reggeon-particle-particle effective vertices. Adopting the Kimber-Martin-Ryskin unintegrated quark and gluon distribution functions of the proton and photon, we thus nicely describe the proton structure function F_{2,c} measured at DESY HERA as well as the transverse-momentum distributions of D mesons created by photoproduction at HERA and by hadroproduction at the Fermilab Tevatron.
