  We studied the single-particle momentum distribution of mass-imbalanced
Efimov states embedded in noninteger dimensions. The contact parameters, which
can be related to the thermodynamic properties of the gas, were calculated from
the high momentum tail of the single particle densities. We studied the
dependence of the contact parameters with the progressive change of the
noninteger dimension, ranging from three (D=3) to two (D=2) dimensions. Within
this interval, we move from the (D=3) regime where the Efimov discrete scale
symmetry drives the physics, until close to the critical dimension, which
depends on the mass imbalance, where the continuum scale symmetry takes place.
We found that the two- and three-body contacts grow significantly in magnitude
with the decrease of the noninteger dimension towards the critical dimension,
impacting observables of resonantly interacting trapped Bose gases.
