All actions for free massive higher-spin fields
William Delplanque
Massive higher-spin states/fields appear in the effective description of various systems from hadrons and nuclei to black holes, whenever the point-particle approximation is justif…

Symmetric vs. chiral approaches to massive fields with spin
William Delplanque, Evgeny Skvortsov
Massive higher spin fields are notoriously difficult to introduce interactions when they are described by symmetric (spin)-tensors. An alternative approach is to use chiral descrip…

Massive spin three-half field in a constant electromagnetic background
William Delplanque, Evgeny Skvortsov
Massive higher-spin fields are difficult to introduce consistent interactions, including electromagnetic and gravitational ones which are clearly exhibited by (non-elementary) high…
