Abstract
The Horizon-10T collaboration have reported observation of Multi-Modal Events (MME) containing multiple peaks suggesting their clustering origin. These events are proven to be hard to explain in terms of conventional cosmic rays (CR). We propose that these MMEs might be result of the dark matter annihilation events within the so-called axion quark nugget (AQN) dark matter model, which was originally invented for completely different purpose to explain the observed similarity between the dark and the visible components in the Universe, i.e., ΩDM∼Ωvisible without any fitting parameters. We support this proposal by demonstrating that the observations, including the frequency of appearance, intensity, the spatial distribution, the time duration, the clustering features, and many other properties nicely match the emission characteristics of the AQN annihilation events in atmosphere. We list a number of features of the AQN events which are very distinct from conventional CR air showers. The observation (non-observation) of these features may substantiate (refute) our proposal.
Highlights
In this work we discuss two naively unrelated stories
This section is devoted to the first part of our story where we describe the Multi-Modal Events (MME) observations [1,2,3,4,5] and argue why the observed events are inconsistent with conventional cosmic rays (CR) interpretation, while the Section 3 is devoted to the second part of our story, the axion quark nugget (AQN) dark matter model
We start with few historical remarks and motivation of the AQN model in Section 3.1, while in Section 3.2 we overview recent observations of CR-like events of some mysterious events which could be explained by the AQN events hitting the Earth
Summary
In this work we discuss two naively unrelated stories. The first one deals with the recent puzzling observations [1,2,3,4,5] by the Horizon-10T (H10T) collaboration of the MultiModal Events (MME). When measured at distances (300–800) m from EAS axis Such intensity would correspond to the CR energy of the primary particle on the level Ep 1019 eV which would have dramatically different event rate in comparison with observed rate recorded by H10T. Before we proceed with our explanation of the proposal to view the MMEs as the AQN events one should mention that similar unusual features of the CR air showers have been noticed long ago for the first time by Jelley and Whitehouse [7] in 1953. One should mention here that a similar conclusion has been reached for a different type of unusual CR-like events It has been argued in [9,10] that the Telescope Array (TA) “mysterious bursts” [11,12] can be naturally interpreted as the AQN events.
