Soft hairy horizons in three spacetime dimensions
Hamid Afshar, Daniel Grumiller, Wout Merbis +3
We discuss some aspects of soft hairy black holes and a new kind of "soft hairy cosmologies", including a detailed derivation of the metric formulation, results on flat space, and…
A deformation of the Curtright action
Sergio Hörtner
We present a deformation of the action principle for a free tensor field of mixed symmetry (2,1) --the Curtright action, a dual formulation of five-dimensional linearized gravity.…
Complex angular momenta approach for scattering problems in the presence of both monopoles and short range potentials
Fabrizio Canfora
It is analyzed the quantum mechanical scattering off a topological defect (such as a Dirac monopole) as well as a Yukawa-like potential(s) representing the typical effects of stron…
On infrared problems of effective Lagrangians of massive spin 2 fields coupled to gauge fields
Fabrizio Canfora, Alex Giacomini, Alfonso R. Zerwekh
In this paper we analyze the interactions of a massive spin-2 particles charged under both Abelian and non-Abelian group using the Porrati-Rahman Lagrangian. This theory is valid u…
The Gribov problem in presence of background field for Yang-Mills theory
Fabrizio Canfora, Diego Hidalgo, Pablo Pais
The Gribov problem in the presence of a background field is analyzed: in particular, we study the Gribov copies equation in the Landau-De Witt gauge as well as the semi-classical G…
Twisted self-duality for higher spin gauge fields and prepotentials
Marc Henneaux, Sergio Hörtner, Amaury Leonard
We show that the equations of motion for (free) integer higher spin gauge fields can be formulated as twisted self-duality conditions on the higher spin curvatures of the spin-…
