In this talk a complete unitarity framework for quantum field theories whose massive scalar excitations propagate at different sound speeds will be presented. Starting from first principles we derive the exact partial-wave unitarity condition for «two-to-two» scattering with arbitrary masses and velocity hierarchies, recovering the standard and massless limits as special cases. Applying the...

We calculate gravitational effective action of the conformal scalar on the perturbed static spacetimes having topologies $S^1 × R^d$, $R × S^d$ and $S^1 × S^d$, generalizing well-known $R^{d+1}$ case. Then, exploiting Wess-Zumino action of conformal anomaly, we apply the result obtained to the problem of primordial perturbations in Early Universe.
