Yulia Ageeva (INR RAS)

11/08/2025, 17:40

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...

На основе предположений о вещественности релятивистского фермионного поля Майораны спина ½ строится его Лагранжиан. В наиболее общей формулировке он содержит два параметра размерности массы. В безмассовой версии модели возможно локальное калибровочно-инвариантное взаимодействие спинорного поля с электромагнитным. Эта аналогичная квантовой электродинамике модель оказывается перенормируемой....

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.
