New Limits On VY Production From CDF: Good, But Also Disappointing

Alas, for once I must say I am not completely happy of one new result by the CDF collaboration...

Sense About Science is a non-profit organization that campaigns in favour of more correct diffusion and use of scientific information. It is a great attempt at increasing the quality of the scientific information in circulation, focusing on evidence and debunking false claims. The web site of the organization explains:
Last Friday Samuel Ting, the winner of the 1975 Nobel prize in Physics for the co-discovery of the J/ψ particle, gave a seminar in the packed CERN main auditorium on the latest results from AMS, the Alpha Magnetic Spectrometer installed on the international space station.
Being at CERN for a couple of weeks, I could not refrain from following yesterday's talks in the Main Auditorium, which celebrated the 90th birthday of Herwig Schopper, who directed CERN in the crucial years of the LEP construction.

A talk I found most enjoyable was John Ellis'. He gave an overview of the historical context preceding the decision to build LEP, and then a summary of the incredible bounty of knowledge that the machine produced in the 1990s.
After four months of frenzy by over 1500 teams, the very successful Higgs Challenge launched by the ATLAS collaboration ended yesterday, and the "private leaderboard" with the final standings has been revealed. You can see the top 20 scorers below.


I just read with interest the new paper on the arxiv by my INFN-Padova colleague Massimo Passera and collaborators, titled "Limiting Two-Higgs Doublet Models", and I thought I would explain to you here why I consider it very interesting and what are its conclusions.
One year ago I had the pleasure to spend some time with George Zweig during a conference in Crete (ICNFP 2013). He is a wonderful storyteller and a great chap to hung around with, and I had great fun in the after-dinners on the terrace of the Orthodox Academy of Crete overlooking the Aegean sea, drinking raki and chatting about physics and other subjects.
