| Abstract | ||
| This paper investigates the effect of changing kinetic energy on the collision between proton and (Pb) nucleus using the Wood-Saxon model of nucleus density distribution. The foundation of the model its density distribution, which steadily decreases from the center to the periphery. The first results are discussed for P-Pb collisions at center-of-mass energy √ sNN= 0.2 and 5.44 TeV. Optical Glauber method was taken into account in the evaluation, the nucleus is perceived as a continuous distribution of matter devoid of boundaries or density changes. The whole procedure of interaction is carried out analytically, many collisions of P-Pb super relativism can be understood on the basis of geometry using a harmonic oscillator potential within the Woods-Saxon density formula for lead nuclei, where the thickness function increased after the collision, and this result agrees with the experimental data, while its found that the Tp-Pb of the ovelapping function at impact parameter (b) was large within the small values of (b) in the geometric case and then decreased for the large (b). In addition, the numbers of nucleons that the participant (Npar) and binary collision (Ncoll) found in the zone of peripheral collisions were found decrease with increasing the effect parameter (b) due to the influence of deviation fluctuations .The average values for participant and binary collisions at 0.2 TeV are 12.3 and 15.3 at constant impact parameter b=2 fm. | ||
