The formation of dust ion acoustic solitons in an unmagnetized plasma with the electrons' drift velocity has been investigated through the modified Korteweg-de Vries (mKdV) equation. In this case only compressive solitons are found to exist. The mKdV solitons are established to exist in two new ranges of drift velocity (v e ′) for 94≤v e ′ ≤104 and 303.75≤v e ′ ≤306. © 2013 Published by NRC Research Press.
