Evaluating single-scale and/or non-planar diagrams by differential equations
Johannes M. Henn, Alexander V. Smirnov, Vladimir A. Smirnov
We apply a recently suggested new strategy to solve differential equations for Feynman integrals. We develop this method further by analyzing asymptotic expansions of the integrals…
Integrable cosmological models with non-minimally coupled scalar fields
A. Yu. Kamenshchik, E. O. Pozdeeva, A. Tronconi +2
We obtain general solutions for some flat Friedmann universes filled with a scalar field in induced gravity models and models including the Hilbert-Einstein curvature term plus a s…
Particle-like Q-balls
E. Ya. Nugaev, M. N. Smolyakov
Usually the charge and the energy of stable Q-balls vary in a wide range or are even unbounded. In the present paper we study an interesting possibility that this range is parametr…
Theory of gauged Q-balls revisited
I. E. Gulamov, E. Ya. Nugaev, M. N. Smolyakov
In this paper, the main properties of (3+1)-dimensional gauged Q-balls are examined. In particular, it is shown that the relation holds for such gauged Q-b…
The Ultraviolet Properties of N=4 Supergravity at Four Loops
Zvi Bern, Scott Davies, Tristan Dennen +2
We demonstrate that pure N=4 supergravity is ultraviolet divergent at four loops. The form of the divergence suggests that it is due to the rigid U(1) duality-symmetry anomaly of t…
Analytic results for planar three-loop four-point integrals from a Knizhnik-Zamolodchikov equation
Johannes M. Henn, Alexander V. Smirnov, Vladimir A. Smirnov
We apply a recently suggested new strategy to solve differential equations for master integrals for families of Feynman integrals. After a set of master integrals has been found us…
Haag's Theorem in the Theories with Non-physical Particles
K. V. Antipin, M. N. Mnatsakanova, Yu. S. Vernov
Haag's theorem is extended to the case of regular representations of the canonical commutation relations in a non-degenerate indefinite inner product space.
Leading singularities and off-shell conformal integrals
James Drummond, Claude Duhr, Burkhard Eden +3
The three-loop four-point function of stress-tensor multiplets in N=4 super Yang-Mills theory contains two so far unknown, off-shell, conformal integrals, in addition to the known,…
Analytic Q-ball solutions and their stability in a piecewise parabolic potential
I. E. Gulamov, E. Ya. Nugaev, M. N. Smolyakov
Explicit solutions for extended objects of a Q-ball type were found analytically in a model describing complex scalar field with piecewise parabolic potential in (3+1)- and (1+1)-d…
Cosmological Solutions of a Nonlocal Model with a Perfect Fluid
Emilio Elizalde, Ekaterina O. Pozdeeva, Sergey Yu. Vernov +1
A nonlocal gravity model which does not assume the existence of a new dimensional parameter in the action and includes a function , with the d'Alembertian op…
