The Madala hypothesis with Run 1 and 2 data at the LHC

TL;DR

This paper investigates the Madala hypothesis, proposing a new heavy scalar particle H, and analyzes its compatibility with Run 1 and Run 2 LHC data, suggesting it could explain certain anomalies.

Contribution

It provides a combined analysis of Run 1 and Run 2 data, demonstrating the consistency of the Madala hypothesis across different experimental results.

Findings

Constraints from Run 2 data are compatible with Run 1 results.

The Madala hypothesis remains a viable explanation for observed anomalies.

The underlying theory involves a two Higgs doublet model with a scalar singlet.

Abstract

The Madala hypothesis postulates a new heavy scalar, H, which explains several independent anomalous features seen in ATLAS and CMS data simultaneously. It has already been discussed and constrained in the literature by Run 1 results, and its underlying theory has been explored under the interpretation of a two Higgs doublet model coupled with a scalar singlet, $S$. When applying the hypothesis to Run 2 results, it can be shown that the constraints from the data are compatible with those obtained using Run 1 results.
