      abstract     = {It has long been known that the gluon propagator in
                      Landau-gauge QCD exhibits a mass gap; and its emergence has
                      been ascribed to the action of the Schwinger mechanism in
                      the gauge sector of QCD. In the present work, we relate this
                      property to the physical mass gap of QCD by considering two
                      observables associated with confinement and chiral symmetry
                      breaking, namely the confinement-deconfinement transition
                      temperature and the pion decay constant, respectively. It
                      turns out that the first observable is linearly proportional
                      to the gluon mass gap, a fact that allows us to assign a
                      direct physical meaning to this scale. Moreover, we identify
                      three distinct momentum regimes in the gluon propagator,
                      ultraviolet, intermediate, and deep infrared, and assess
                      their impact on the aforementioned observables. Both
                      observables are sensitive to the first two regions of
                      momenta, where functional approaches essentially coincide,
                      but are insensitive to the third, deep infrared, regime. The
                      combined information is used for a simple fit for the gluon
                      propagator, all of whose parameters admit a clear physical
                      interpretation. Finally, we discuss how this fit can help us
                      access the intertwined dynamics of confinement and chiral
                      symmetry breaking in QCD-type theories.},
