Main Article Content
Abstract
A mid-point technique is introduced to overcome the difficulties in other techniques. The modied e⁄ective interaction quark potential which uses to calculate different properties of the NJL model such as the constituent quark mass, pressure, and energy density is solved using the present technique. The present method gives good accuracy for the mathematical problem and avoids the physical di¢ culty in the previous works.
