Nonlinear waves in a quark gluon plasma

اثرات برخورد سر به سر دو پالس از باریون های ایجاد شده در پلاسمای كوارك - گلوئون QGP - كه با شبه سالیتون ها ی معادله kdv توصیف می گردند - مطالعه می شود . ... Head on collision between two pulses of baryons created in a Quark-Gluon plasma (QGP) has been investigated. It is shown that the baryon densities are described by soliton-like profiles of the KdV equation in this medium. Both zero and also nonzero temperature structure of QGP have been considered. Relativistic hydrodynamic equation of this system is expanded. Finally the evolving equation of baryon densities and also energy densities has been derived in this medium. It is shown that the baryon and also energy densities are scattered with a phase change which is calculated.
