英文摘要 | We propose a modified Balistsky-Fadin-Kuraev-Lipatov (BFKL) equation for the summation of large ln(1/x), x being the Bjorken variable, which contains an extra dependence on the momentum transfer Q compared to the conventional BFKL equation. In the derivation of the BFKL kernel. The modified equation gives a slower rise of the gluon distribution faction with 1/x for smaller Q, such that the predications for the structure functions F2, L(x, Q2) involved in deep inelastic scattering match the HERA data. These results are similar to those obtained form the Ciafaloni-Catiani-Fiorani-Marchesini equation, which embodies both the ln Q and ln(1/x) summations. The reason that the conventional BFKL equation can not be applied to the low Q (soft pomeron dominant) region is given. |
