Abstract
The investigation of dressed electrostatic and energy ion acoustic solitary waves in a warm plasma composed fluid of ions, Maxwillian positrons and fast nonthermal electrons are elaborated. The plasma system is reduced to KdV equation that obtained usingreductive perturbation method. For enlarged amplitude, the higher order perturbed equation is proposed. The positron parametersand nonthermal electron effects on broadband dressed electric field and energy are discussed. (C) 2016 The Authors. Production and hosting by Elsevier B.
