SUMMARY
The discussion centers on the appropriateness of using the Kronecker delta integral, specifically the expression \int \delta(m_h-2E) dE. Participants argue that this integral is more suitably represented by the Dirac delta distribution rather than the Kronecker delta. The correct approach involves applying the formula \int_{\mathbb{R}} \mathrm{d} x \delta[f(x)] g(x)=\sum_{j} \frac{1}{\left |f'(x_j) \right|} g(x_j), where f is a function with first-order roots x_j.
