On the particle content of MHS theory
Maro Cvitan, Predrag Dominis Prester, Stefano Giaccari +2
The Moyal-Higher-Spin (MHS) formalism, involving fields dependent on spacetime and auxiliary coordinates, is an approach to studying higher spin (HS)-like models. To determine the…
HS in flat spacetime. YM-like models
L. Bonora, M. Cvitan, P. Dominis Prester +2
We introduce and analyse a few examples of massless higher spin theories in Minkowski spacetime. They are defined in terms of master fields, i.e. fields defined in the whole phase…
HS in flat spacetime. The effective action method
L. Bonora, M. Cvitan, P. Dominis Prester +2
This is the first paper in a series of three dealing with HS theories in flat spacetime. It is divided in three parts. The first part is an elaboration on the method of effective a…
Axial gravity: a non-perturbative approach to split anomalies
L. Bonora, M. Cvitan, P. Dominis Prester +3
In a theory of a Dirac fermion field coupled to a metric-axial-tensor (MAT) background, using a Schwinger-DeWitt heat kernel technique, we compute non-perturbatively the two (odd p…
Worldline quantization of field theory, effective actions and structure
L. Bonora, M. Cvitan, P. Dominis Prester +3
We formulate the worldline quantization of a massive fermion model coupled to external higher spin sources. We use the relations obtained in this way to show that its regularized e…
One-loop effective actions and higher spins. II
L. Bonora, M. Cvitan, P. Dominis Prester +2
In this paper we continue and improve the analysis of the effective actions obtained by integrating out a scalar and a fermion field coupled to external symmetric sources, started…
Axial gravity, massless fermions and trace anomalies
L. Bonora, M. Cvitan, P. Dominis Prester +3
This article deals with two main topics. One is odd parity trace anomalies in Weyl fermion theories in a 4d curved background, the second is the introduction of axial gravity. The…
One-loop effective actions and higher spins
L. Bonora, M. Cvitan, P. Dominis Prester +3
The idea we advocate in this paper is that the one-loop effective action of a free (massive) field theory coupled to external sources (via conserved currents) contains complete inf…
Massive fermion model in 3d and higher spin currents
L. Bonora, M. Cvitan, P. Dominis Prester +2
We analyze the 3d free massive fermion theory coupled to external sources. The presence of a mass explicitly breaks parity invariance. We calculate two- and three-point functions o…
Parity-odd surface anomalies and correlation functions on conical defects
Maro Cvitan, Predrag Dominis Prester, Silvio Pallua +2
We analyse the parity-odd ("type P") surface anomalies of the energy-momentum tensor correlators in conformal field theories, with an emphasis on d=4 and d=3 dimensional spacetimes…
Curing black hole singularities with local scale invariance
Predrag Dominis Prester
We show that Weyl-invariant dilaton gravity provides a description of black holes without classical spacetime singularities. Singularities appear due to ill-behaviour of gauge fixi…
Symmetries and gravitational Chern-Simons Lagrangian terms
Loriano Bonora, Maro Cvitan, Predrag Dominis Prester +2
We consider some general consequences of adding pure gravitational Chern-Simons term to manifestly diff-covariant theories of gravity. Extending the result of a previous paper we e…
Small black holes in the large D limit
Predrag Dominis Prester
The large D limit of AdS_2 X S^{D-2} solutions in the particular higher-derivative Lovelock-type theory is analyzed. The theory and the solutions were originally considered in an a…
Stationary rotating black holes in theories with gravitational Chern-Simons Lagrangian term
Loriano Bonora, Maro Cvitan, Predrag Dominis Prester +2
We study the effects of introducing purely gravitational Chern-Simons Lagrangian terms in ordinary Einstein gravity on stationary rotating black hole solutions and on the associate…
Gravitational Chern-Simons terms and black hole entropy. Global aspects
L. Bonora, M. Cvitan, P. Dominis Prester +2
We discuss the topological and global gauge properties of the formula for a black hole entropy due to a purely gravitational Chern-Simons term. We study under what topological and…
Gravitational Chern-Simons Lagrangian terms and spherically symmetric spacetimes
Loriano Bonora, Maro Cvitan, Predrag Dominis Prester +2
We show that for general spherically symmetric configurations, contributions of general gravitational and mixed gauge-gravitational Chern-Simons terms to the equations of motion va…
Gravitational Chern-Simons Lagrangians and black hole entropy
Loriano Bonora, Maro Cvitan, Predrag Dominis Prester +2
We analyze the problem of defining the black hole entropy when Chern-Simons terms are present in the action. Extending previous works, we define a general procedure, valid in any o…

We review recent results on near-horizon static black hole solutions and entropy in R^2-corrected N=2 SUGRA in D=5, focusing on actions connected to heterotic string compactified o…
