Physics

So, by now we all know it - there is no 750 GeV resonance in LHC data. But will we ever learn the lesson ?
The facts

Let me start this post by recalling the bare facts, and a quick-and-dirty introduction for anybody who has been on the Moon in the last eight months or so. Last December, the CMS and ATLAS experiments at the CERN LHC collider presented in two back-to-back seminars their first results on data collected at unprecedented proton-proton collision energy of 13 TeV. The 60% higher center-of-mass energy with respect to collisions analized in the previous years left hopes alive for the discovery of some new physics process, which could have been hiding until then thanks to the large required energy to turn on the reactions. 
As explained in the first installment of this series, these questions are a warm-up for my younger colleagues, who will in two months have to pass a tough exam to become INFN researchers.

A disclaimer is useful here. Here it is:

By the way, when I wrote the first question yesterday I thought I would not need to explain it in detail, but it just occurred to me that a disclaimer would be useful. Here it is:
Today I wish to start a series of posts that are supposed to help my younger colleagues who will, in two months from now, compete for a position as INFN research scientists. 
The INFN has opened 73 new positions and the selection includes two written exams besides an evaluation of titles and an oral colloquium. The rules also say that the candidates will have to pass the written exams with a score of at least 140/200 on each, in order to access the oral colloquium. Of course, no information is given on how the tests will be graded, so 140 over 200 does not really mean much at this point.

The Large Underground Xenon (LUX) dark matter experiment, which operates beneath a mile of rock at the Sanford Underground Research Facility in the Black Hills of South Dakota, has completed its search for the missing matter of the universe yielding no trace of a dark matter particle. 

LUX's extreme sensitivity makes the team confident that if dark matter particles had interacted with the LUX's xenon target, the detector would almost certainly have seen them. In a 'what you don't find is important also' sense, these new limits on dark matter detection will allow scientists to eliminate many potential models for dark matter particles. 

My book "Anomaly! - Collider Physics and the Quest for New Phenomena at Fermilab" is slowly getting its finishing touches, as the second round of proofreading draws to a close. The book is scheduled to appear in bookstores on November 5th, and it makes sense to start planning some events for its presentation.
One such event will take place at the CERN library on November 29th, at 4PM. I am told that CERN already ordered the book to sell it in its bookshop, so it will be good to present the work to the community there - after all, the book is for everybody but I expect that it can be of higher interest to scientists and people in some way connected to research in High-Energy physics.
