خصائص الجسيمات المنبعثة في الاتجاهين الأمامي و الخلفي في تصادمات الكربون مع المستحلب النووي عند الطاقة العالية

Abstract EN

Experimental data on relativistic (shower) and fast (grey) hadrons emitted in the forward and backward hemispheres ( , (FHS,BHS), in the collision of beam with emulsion nuclei at 4.5AGeV/c are presented and analyzed.

The correlations between multiplicities of shower particles are also investigated.

The mean values of the multiplicities of the produced forward particles are strongly dependent on the projectile mass number, ,and its energy while those of the backward ones are nearly independent of .Finally, the ratio ( ) is found to increase with increasing the projectile mass and decrease rapidly with increasing the target size ( -value), while ( ) seems to exhibit a limited behavior in the region of
