One of the few physics measurements that the LHC experiments are already in the position of producing, with the week-worth of proton-proton collision data they have collected last December, is that of the Bose-Einstein intereference between identical bosons.

There are twenty-four elementary fermions in the standard model. Sure, they are arranged in a very tidy, symmetrical structure of three families of eight fermions (two leptons and six quarks), which is not too unpleasant to behold. And of course, if one is willing to forget the fact that the quantum-chromodynamical charge of quarks does make them different, then the picture is even tidier: 12 fermions, six of them quarks and six of them leptons, arranged in three families of four.

One of the positive side-effects of preparing a seminar is being forced to get up-to-date with the latest experimental and theoretical developments on the topic. And this is of particular benefit to lazy bums like myself, who prefer to spend their time playing online chess than reading arxiv preprints.

It happened last week, in the course of putting together a meaningful discussion of the state of the art in global electroweak fits to standard model observables, and their implications for the unknown mass of the Higgs boson: by skimming the hep-ph folder I found a very recent paper by a colleague in Padova, which I had shamefully failed to notice in the last couple of careless visits.
