Renormalons on the lattice
We present the first lattice calculation of the B-meson binding energy \labar and of the kinetic energy \lambda_1/2 m_Q of the heavy-quark inside the pseudoscalar B-meson. In order to cancel the ambiguities due to the ultraviolet renormalons present in the operator matrix elements, this calculation...
