Yesterday I read with interest and curiosity some pages of a book on the search and discovery of the Higgs boson, which was published last March by Rizzoli (in Italian only, at least for the time being). The book, authored by physics professor and ex CMS spokesperson Guido Tonelli, is titled "La nascita imperfetta delle cose" ("The imperfect birth of things").
The 2012 measurements of the Higgs boson, performed by ATLAS and CMS on 7- and 8-TeV datasets collected during Run 1 of the LHC, were a giant triumph of fundamental physics, which conclusively showed the correctness of the theoretical explanation of electroweak symmetry breaking conceived in the 1960s.
The Higgs boson signals found by the experiments were strong and coherent enough to convince physicists as well as the general public, but at the same time the few small inconsistencies unavoidably present in any data sample, driven by statistical fluctuations, were a stimulus for fantasy interpretations. Supersymmetry enthusiasts, in particular, saw the 125 GeV boson as the first found of a set of five. SUSY in fact requires the presence of at least five such states.
Next Monday, the Italian city of Rome will swarm with about 700 young physicists. They will be there to participate to a selection of 58 INFN research scientists. In previous articles (see e.g.
Particle physics conferences are a place where you can listen to many different topics - not just news about the latest precision tests of the standard model or searches for new particles at the energy frontier. If we exclude the very small, workshop-like events where people gather to focus on a very precise topic, all other events do allow for the contamination from reports of parallel fields of research. The reason is of course that there is a significant cross-fertilization between these fields.
Gino Bolla was an Italian scientist and the head of the Silicon Detector Facility at Fermilab. And he was a friend and a colleague. He died yesterday in a home accident. Below I remember him by recalling some good times together. Read at your own risk.
news of your accident reach me as I am about to board a flight in Athens, headed back home after a conference in Greece. Like all unfiltered, free media, Facebook can be quite cruel as a means of delivering this kind of information, goddamnit.
As an old time chessplayer who's stopped competing in tournaments, I often entertain myself with the odd blitz game in some internet chess server. And more often than not, I play rather crappy chess. So nothing to report there... However fluctuations do occur.
I just played a combinative-style game which I wish to share, although I did not have the time yet (and I think I won't have time in the near future) to check the moves with a computer program. So my moves might well be flawed. Regardless, I enjoyed playing the game so that's enough motivation to report it here.
