| 英文摘要 | The renormalization issue in the reparametrization invariance in heavy quark effective theory and NRQCD is investigated. I argue that the renormalization of the transformation of the heavy quark field under the variation of the velocity parameter V is attributed to the renormalization of the small component field in the proposed transformation. I derive the matching conditions for determining the renormalized small component field by imposing an infinitesimal transformation of V on the relations between the Green's functions in QCD full theory and those in the effective theory. As an application, I determine the renormalized transformation to order 1/m(2) using the matching conditions. The obtained result is in disagreement with that determined by the indirect method. |
