Considered is N=1 supersymmetric SU(Ncβ) QCD (SQCD) with 1β€NFββ€Ncββ1 equal mass quark flavors in the fundamental representation.
Using a number of independent arguments for different variants of transition
between the confinement and higgs regimes, it is shown that transitions between
these regimes are not crossovers but the phase transitions.
These are counterexamples to a widely spread opinion, originating from the
paper of E. Fradkin and S.H. Shenker [10], about absence of the phase
transition between the confinement and higgs phases.Comment: 10 pages, title and abstract changed, text expanded, argumentation
