Interplay of femtoscopic and charge-balance correlations

Correlations driven by the constraints of local charge conservation have been shown to provide insight into chemical evolution and diffusivity high-temperature matter created in ultrarelativistic heavy ion collisions. Two-particle correlations final-state interactions allowed extraction critical femtoscopic space-time information about expansion dissolution same Whereas from mainly appear at small relative momenta, a few tens MeV/$c$, charge-balance extend over range hundreds MeV/$c$. In nearly all previous analyses, this separation scales is used focus solely on one class or other. The purpose study quantitatively understand degree which distort interpretation vice versa.
