Twisted Tachyon Condensation in Closed String Field Theory


We consider twisted tachyons on C/ZN orbifolds of bosonic closed string theory. It has been conjectured that these tachyonic instabilities correspond to decays of the orbifolds into flat space or into orbifolds with smaller deficit angles. We examine this conjecture using closed string field theory, with the string field truncated to low-level tachyons. We… (More)
