Abstract
We discuss a new way to develop the exactly solvable model of the QCD critical endpoint by matching the deconfinement phase transition line for the system of quark-gluon bags with the line of their vanishing surface tension coefficient. In contrast to all previous findings in such models the deconfined phase is defined not by an essential singularity of the isobaric partition function, but by its simple pole. As a result we find out that the first order deconfinement phase transition which is defined by a discontinuity of the first derivative of system pressure is generated by a discontinuity of the derivative of surface tension coefficient.
