Abstract
The \( \Phi_{{{\rm pt}}}^{}\) -variable, a measure of statistical correlation of particle momenta, introduced by Mrówczyński and Gaździcki, has been calculated for the events simulated with a simple thermal toy model. It is shown that mixing two thermal sources of unequal temperature can result in negative values of \( \Phi_{{{\rm pt}}}^{}\) .
