New gauge fixing condition with single gauge parameter proposed by the authors is applied to the level truncated analysis of tachyon condensation in cubic open string field theory. It is found that the only one real non-trivial vacuum solution persists throughout the well-defined region of the gauge parameter, while the other solutions are turned out to be gauge-artifacts. Contrary to the previously known singular behavior in the Feynman-Siegel gauge, tachyon potential is remarkably smooth enough around Landau-type gauge. © SISSA 2007.
