Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    Dilaton, conformal symmetry and Weyl invariance
    (2016-05-14) Monin, Alexander
    I’ll show how to implement spontaneous breaking of conformal symmetry at the quantum level from the IR perspective. In other words how to introduce consistently the (massless) dilaton. Given the importance of the Weyl invariance in the construction it is necessary to understand the relation between conformal symmetry and Weyl invariance. I’ll touch upon the issue and present examples of theories that are conformally invariant but do not admit Weyl invariant generalizations.

    Effects of extra degrees of freedom on decay rate of metastable topological objects.
    (2010-08) Monin, Alexander
    In present study we consider decays of metastable strings and walls. Both cases of zero and finite temperature are considered. An appropriate interpretation of the thermal result allowed to find the probability of the decay in collisions of Goldstone bosons. The developed technique was used to find the rate of e^+e^- pair production in external field stimulated by photon.
