Head-on collision of dust magnetoacoustic solitary waves in magnetized plasmas

The head-on collision of dust magnetoacoustic solitary waves (DMASWs) is studied in magnetized electron-ion-dust plasma. The extended Poincare-Lighthill-Kuo perturbation method is used to derive the Korteweg de Vries equations for DMASWs in this three-component plasma. The effects of the magnetic field intensity B-0, the number of electrons residing on dust surface Z(d), the ratio of electron to dust number density delta, the ratio of electron to ion temperature sigma, and the ratio of dust acoustic velocity to dust Alfven velocity beta on the phase shift are investigated. It is found that these parameters can significantly influence the phase shifts of colliding DMASWs. The present investigation may be beneficial to understand the interaction between two DMASWs that may occur in plasma with dust impurities situations.
