Can scalars matter? A vector bilepton phenomenologic example

TL;DR

This paper challenges the common assumption that scalar contributions are less significant than vector ones in physical observables, demonstrating that scalars can lead to interesting phenomena under certain conditions.

Contribution

It provides a phenomenological example showing scalars can be as important as vectors, contrary to typical expectations, highlighting the need to reconsider their role in models.

Findings

Scalar contributions can be significant in certain parameter spaces.

Scalar effects may lead to novel phenomena not accounted for by vector dominance.

The study emphasizes the importance of not dismissing scalar contributions in phenomenological analyses.

Abstract

Expecting scalar contributions to be less important to a given observable signal than vector ones, in usual scenarios, is a natural intuition. Such assertion should hold for a great part of physically relevant parameter space within most models of interest. In this work, besides stressing that the proposition is not general, we show how the alternative possibility may give light to interesting phenomena.
