Microfabrication of Super Absorbent Polymer Structure Using Nanoimprinting and Swelling Process

Abstract

We consider a physical scenario for ultra-relativistic heavy-ion collisions where, at the early stage, only transverse degrees of freedom of partons are thermalized, while the longitudinal motion is described by free streaming. When the energy density of the partonic system drops to a certain critical value, the partons hadronize and the newly formed hadronic system freezes out. This sudden change is described with the help of the Landau matching conditions followed by the simulations done with THERMINATOR. The proposed scenario reproduces well the transverse-momentum spectra, the elliptic flow coefficient v 2 and the HBT radii of pions and kaons studied at RHIC (Au + Au collisions at √ s NN = 200 GeV). It also reproduces quite well 0954-3899/10/094023+06$30.00
