Nucleon-nucleon collision profile and cross section fluctuations

Understand

The nucleon-nucleon collision profile, being the basic entity of the wounded nucleon model, is usually adopted in the form of hard sphere or the Gaussian shape.

• We suggest that the cross section fluctuations given by the gamma distribution leads to the profile function which smoothly ranges between the both limiting forms.
• Examples demonstrating sensitivity of profile function on cross section fluctuations are discussed.
