Neutrino Mixing CP-violating Phenomenology with only Two Free Parameters
The flavor-geometric semi-empirical phenomenology appears a powerful source of new basic ideas in the Standard Model Flavor Sector.
Most recent new idea is CP-nonconservation as cause of deviation from exact Euclidean 3-space geometric symmetry of neutrino bimaximal approximation. It is represented by cos-squared Dirac CP-phase (CPph) [1. ResearchGate/L, 9/16],
cos^2(2θ12) +cos^2(2θ23) + cos^2(2θ13) = 1 + cos^2(CPph), (1)

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.
The physics of nanometer sized bubbles is mysterious and controversial. Gas bubbles in liquids are unstable.[2] Also large air bubbles in water are not stable. Even if we keep them somehow from rising to the surface and popping, the surface tension of the bubble itself presses the air out of the bubble and into the liquid! The physicist calls this ‘Laplace pressure’.[3] We do not notice this with large bubbles. However, with a nanobubble, the Laplace pressure dissolves it in a few micro seconds.

Dirac CP-violating phase from deviation of neutrino mixing from geometric bimaximal approximation 

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. 

Dear Gino,

   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.

Complementarity relation between CP-violating phase and neutrino mixing reactor angle

The book "Anomaly! Collider Physics and the Quest for New Phenomena at Fermilab" is going to press as we speak, and its distribution in bookstores is foreseen for the beginning of November. In the meantime, I am getting ready to present it in several laboratories and institutes. I am posting here the coordinates of events which are already scheduled, in case anybody lives nearby and/or has an interest in attending.
- On November 29th at 4PM there will be a presentation at CERN (more details will follow).
