We summarize the properties of the 1-parameter family of covariant gauges ('a-gauges') of bosonic open string field theory given in papers [M. Asano and M. Kato, Frog. Theor. Phys. 117 (2007), 569, hep-th/0611189; J. High Energy Phys. 01...
A general class of gauges for open string field theory, for which the gauge fixing condition is given by linear equations with respect to string field, is investigated in detail. This class of gauges includes almost all known ones like Siegel gaug...
A single-parameter family of covariant gauge fixing conditions in bosonic string field theory is proposed. This is a natural string field counterpart to the covariant gauge in the conventional gauge theory, which includes the Landau gauge, as well...
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 per...
