• 論文の詳細を見る

• We compute the Isgur-Wise function using the heavy quark effective theory formulated on the lattice. The kinetic energy term of the heavy quark is included to the action as well as the terms remaining in the infinite mass limit. The classical velocity of the heavy quark is renormalized on the lattice and we determine the renormalized velocity non-perturbatively using the energy-momentum dispersion relation. The slope of the Isgur-Wise function at zero recoil is obtained at β=6.0 on a 24^3×48 lattice and the size of O(1/m_Q)-correction is estimated.
