Phenomenological interpretation of the multi-muon events reported by the CDF collaboration

TL;DR

This paper proposes a new physics model involving three new particles to explain multi-muon events observed by CDF, with specific mass ranges and decay properties.

Contribution

It introduces a phenomenological model with three new states that cascade decay and decay into tau pairs, explaining the observed multi-muon event topology.

Findings

The model accounts for the topology and kinematic features of the data.

The lightest state decays into tau pairs with a 20 ps lifetime.

Masses of the new states are 15, 7.3, and 3.6 GeV/c^2.

Abstract

We present a phenomenological conjecture of new physics that is suggested by the topology and kinematic properties of the multi-muon events recently reported by the CDF collaboration. We show that the salient features of the data can be accounted for by postulating the pair production of three new states h1, h2, and h3 with masses in the range of 15, 7.3 and 3.6 GeV/c^2, respectively. The heavier states cascade-decay into the lighter ones, whereas the lightest state decays into a tau pair with a lifetime of the order of 20 ps.
