  Transverse momentum correlations were recently measured by the ALICE
collaboration at the LHC. A long-range structure in terms of relative
pseudorapidity of particle pairs is observed. This may imply some signal of the
initial state owing to the shear spread of the correlation. However, the
fluctuations inside a thermally equilibrated medium have to be taken into
account, serving as motivation for this letter. Using lattice Quantum
Chromodynamics (lQCD) constraints, we predicted the development and spread of
balancing correlations caused by energy-momentum conservation. Simultaneously,
we propagated the initial correlation using hydrodynamics to estimate its
effects. Our findings suggest that the resulting correlation, known as ``the
ridge``, is sensitive to both fluctuations in the equilibrated medium and the
pre-equilibrium stage. This can provide important insight into the early stages
of the collision.
