In a few days, scores of Italian post-doctoral researchers in experimental particle physics will get tested on their knowledge of the matter, without any promise of a position, but just to get one further "stamp" on their curriculum, testifying that they are competent enough to be worth offering a temporary position by INFN, the Italian Institute for (sub)Nuclear Physics. So this is a  national exam, with the sole purpose of giving a green light to be admitted to two-year positions , which are typically paid less than 1400 euros a month, and which are so far not available. Frankly, I feel ashamed, since I myself work for INFN, and I strongly disagree with its current recruitment policies.

If you have followed this blog for long enough, dear readers, the words "multi-muons", "anomalous muons", or even "lepton jets" are not foreign to you. They all refer to a paper appeared on the ArXiv on the evening of Halloween last year. In the paper the CDF collaboration published the results of a detailed analysis which described how a component of collider data containing two or more muons could not be explained by known Standard Model processes.

In a few days italian post-docs working in high-energy physics will be asked to gather for a nasty exam, held by the INFN -the italian institute for nuclear physics- to qualify valiant researchers for future hiring in the institute.

The exam generated a wave of outrage among the very pool of people at which it is aimed: the scores of "precari" (temporary workers) who are spending the best years of their life to try and make a career in particle physics.  Let me explain why that is so.
