  2. 4. Summation of UV divergences in maximally supersymmetric Yang-Mills theories in diverse dimensions
    Prof. Dmitry Kazakov (JINR)
    09/09/2015, 09:30
    We consider the UV divergences in scattering amplitudes in maximally supersymmetric Yang-Mills theories in diverse dimensions: (D=6, N=2), (D=8, N=1) and (D=10, N=1) cases. The recurrence relation is found that allows one to get the leading divergences in all orders of PT for the four point amplitude. It is checked by explicit calculations in several loops. Infinite summation of the leading...

  3. 22. Zero modes, heat kernel expansions, spectral zeta functions. A novel approach.
    Dr Mateos Guilarte Juan (Universidad de Salamanca)
    09/09/2015, 10:00
    Many phenomena in statistical physics and quantum field theory are effectively described by means of spectral zeta function techniques. In particular, one-loop quantum fluctuations around classical backgrounds engender divergences that may be regularized via spectral zeta function analytic continuation regularization. Tipically, in solitonic and/or gravitational backgrounds, e.g., magnetic...

  4. 100. Renormalization-group improved inflationary scalar electrodynamics and SU(5) scenarios
    Ekaterina Pozdeeva (SINP MSU)
    09/09/2015, 10:20
    The possibility to construct inflationary models for the renormalization-group (RG) improved potentials corresponding to scalar electrodynamics and to SU(2) and SU(5) models is investigated. In all cases, the tree-level potential, which corresponds to the cosmological constant in the Einstein frame, is seen to be nonsuitable for inflation. Rather than adding the Hilbert-Einstein term to...

  5. 43. Nonlocal gravity from generalised spacetime structure
    Alexey Golovnev
    09/09/2015, 10:40
    There are two basic ways of modifying gravity: considering either more general theories for the metric or allowing spacetime degrees of freedom besides the metric. Here the aim is to find possible relations between gravitational theories obtained within these two seemingly distinct approaches. In the framework of the so called C-theories the spacetime connection has a prescribed relation to...
