# Profile of multiboson signals

## TL;DR

This paper examines the detectability of wide bump signals from multiboson resonance decays in hadronic final states, highlighting the challenges in identifying such signals amid background noise.

## Contribution

It provides an analysis of the visibility of wide bump signals from triboson and quadriboson decays, emphasizing the limitations of current detection methods.

## Key findings

- Sensitivity to triboson bumps is limited, allowing moderate signals to go unnoticed.
- Quadriboson cascade decay signals are nearly indistinguishable from background in current searches.
- Current methods are insufficient for reliably detecting wide bump signals from multiboson processes.

## Abstract

We investigate the visibility of signals characterised by wide bumps over a smoothly falling background that cannot be accurately predicted by Monte Carlo calculations. Examples of such are the wide bumps that triboson and quadriboson resonance cascade decays would yield in diboson resonance searches in fully hadronic final states. We find that the sensitivity to triboson bumps is rather small: signals of a moderate size could be present in current data and yet remain unnoticed. For quadriboson cascade decays the signals can hardly be distinguished from the background in the current searches.
