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 …

In four spacetime dimensions there exist two off-shell formulations for the massless multiplet
of superspin (s+ 1 2), where s= 2, 3,…. These supersymmetric higher spin gauge theories …

A bstract 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 …

A bstract The linearized spectrum and the algebra of global symmetries of conformal higher-
spin gravity decompose into infinitely many representations of the conformal algebra. Their …

This work examines the dynamical mass generation for the photon in Rarita–Schwinger
QED. We focus our attention on the cases of\(\omega= 2, 3\) dimensional spacetime. In …

A bstract We formulate the worldline quantization (aka deformation quantization) of a
massive fermion model coupled to external higher spin sources. We use the relations …

In this work, we study the perturbative generation of the gauge invariant effective action for
the non-Abelian gauge field in a (2+ 1)-dimensional spacetime. We present a detailed …

We introduce and analyse a few examples of massless higher spin theories in Minkowski
spacetime. They are defined in terms of master fields, ie fields defined in the whole phase …

In this paper, we study the one-loop induced photon's effective action in the very special
relativity electrodynamics in (2+ 1)(2+ 1) spacetime (VSR VSR–QED _ 3 QED 3). Due to the …

A bstract We analyze a novel approach to gauging rigid higher derivative (higher spin)
symmetries of free relativistic actions defined on flat spacetime, building on the formalism …
