The CDF authors of the study which is causing ripples in the blogosphere have published tonight a second paper, where they try to interpret the excess of events with large impact-parameter muon tracks within a phenomenological model of new physics. You can find their paper here.
In short, they try to fit the observed muon multiplicity within narrow cones, as well as their quite peculiar kinematic characteristics, with the decay of a heavy object which produces a cascade of long-lived particles, ending with a multi-muon signature.
The paper was born as part of the other document (see the story in the post below), but was extracted from it and published separately since this was the best way to proceed promptly to a publication of both. As you see by checking the arxiv entry, this second preprint has only the names of the very authors of the study on the multi-muon anomaly.
I will have more detail on the physics later…
