Detailed Description

Class implementing the ideal HRG model in the canonical ensemble.

Calculation of particle densities proceeds as described in F. Becattini, U. Heinz, Z. Phys. C76, 269 (1997), https://arxiv.org/pdf/hep-ph/9702274.pdf

Particle number fluctuations are determined through the derivatives with respect to the fictitous fugacities, as is usually done in HRG, see e.g. https://arxiv.org/pdf/nucl-th/0404056.pdf
