Short-range correlations in bosonic Helium clusters, composed of He4 atoms, are studied utilizing the generalized contact formalism. The emergence of universal n-body short-range correlations is formulated and demonstrated numerically via Monte Carlo simulations. The values of the n-particle contacts are evaluated for n≤5. In the thermodynamic limit, the two-body contact is extracted from available experimental measurements of the static structure factor of liquid He4 at high momenta, and found in a good agreement with the value extracted from our calculations.
