Vibrational modes of Q-balls
A. Kovtun, E. Nugaev, A. Shkerin
We study linear perturbations of classically stable Q-balls in theories admitting analytic solutions. Although the corresponding boundary value problem is non-Hermitian, the analys…
Gravity, Scale Invariance and the Hierarchy Problem
Mikhail Shaposhnikov, Andrey Shkerin
Combining the quantum scale invariance with the absence of new degrees of freedom above the electroweak scale leads to stability of the latter against perturbative quantum correcti…
Solving puzzles of spontaneously broken spacetime symmetries
Ivan Kharuk, Andrey Shkerin
We establish a classical analog of the Nambu-Goldstone theorem for spontaneous breaking of spacetime symmetries. It provides a counting rule for independent Nambu-Goldstone fields…
Conformal symmetry: towards the link between the Fermi and the Planck scales
Mikhail Shaposhnikov, Andrey Shkerin
If the mass of the Higgs boson is put to zero, the classical Lagrangian of the Standard Model (SM) becomes conformally invariant (CI). Taking into account quantum non-perturbative…
