Joseph C. V\'arilly, Jos\'e M. Gracia-Bond\'ia
TL;DR
This paper revisits the concept of divergent quantum amplitudes, challenging traditional power-counting, and introduces new models for free and interacting bosonic field theories of any mass and spin.
Contribution
It refines the notion of divergent amplitudes, enabling the development of novel bosonic field theory prototypes beyond standard methods.
Findings
New prototypes for bosonic field theories of any mass and spin
Refinement of divergent amplitude concept
Potential for advancing quantum field theory models
Abstract
Stora and coworkers refined the notion of divergent quantum amplitude, somewhat upsetting the standard power-counting recipe. This unexpectedly clears the way to new prototypes for free and interacting field theories of bosons of any mass and spin.
