We investigate how competitive gravitational wave detectors can be to current and near-future colliders in probing a model where the new physics is completely encapsulated modified scalar sector. For this, we study an additional logarithmic term arises potential due non-trivial path integral measure, which constructed using effective field theory. This alters dynamics of cosmological phase transitions could lead potentially detectable waves from early Universe. Our results confirm expectation that intensity such spectrum highly correlated field's self-coupling, experiments therefore used probe these couplings with accuracy projected sensitivity colliders.
