  We present results for the static-light meson from unquenched lattice QCD.
The unquenched gauge configurations were generated using the non-perturbatively
improved clover action. At the fixed lattice spacing of 0.1 fm the lightest sea
quark mass used is a third of the strange quark mass. A comparison is made
between heavy-light chiral perturbation theory and the f_B^(static) decay
constant. The mass of the bottom quark is also reported: m_b(m_b) = 4.25(2)(11)
GeV, where the first error is statistical and the last error is the systematic
uncertainty.
