I have to say that this is entirely predictable, the scientists involved knew it was almost certainly an experimental error and they still published.
Not only did they publish, but they hit the PR circuit and got blanket coverage on TV and newspapers down to dossers on internet forums like this.
The whole point is the sensation. I’m betting that around about now some people have to decide about the next few years funding for CERN and they have to make themselves look worthwhile. This is certainly true of NASA, they periodically spit out stories of life on the moon / mars / some other galaxy, almost always right before congress looks at their funding.
Real science is almost always massively parallel, slow, incremental and (in the short term) predictable. As i always say to students, if your experiment looks too good to be true, thats because it is.
