摘要: Abstract The ratios of the masses D( p − d ) branes to D in open bosonic string field theory are computed within modified level truncation approximation Moeller et al. At lowest non-trivial requiring addition new primary states, we find evidence rapid convergence expected result for 2⩽ ⩽6 providing additional consistency this approximation.
