Final results of searches for particles decaying to photon pairs in 2015 data keep hopes alive for imminent ground-breaking discovery

On December 15th last year, as the physics coordinators of the ATLAS and CMS collaborations showcased the results of their new searches, particle physicists around the world held their breath. Both experiments showed preliminary results from the analysis of LHC data acquired during 2015 at 13 TeV. That unprecedented energy made the potential for new discoveries high.

Today, while Americans set up their barbecues and prepare to celebrate their Independence, particle physicists around the world have a different reason to celebrate. Four years ago today is when the Higgs boson got officially declared a confirmed new particle in the subatomic zoo.

As my blogging here has been erratic in the last couple of weeks, I feel I need to explain to my 23 readers (what citation is this BTW?) what I have been up to. So this post does not contain any physics, and is rather about how a physicist fights for some space and time for himself and his family, decoupled from his daily occupations, and hopefully lowers his stress level. 
I left my home in Venice on June 15th at four in the morning with my fiancee and my two kids (Filippo, 17 and Ilaria, 13 years old), headed  to Elafonisos, a tiny island in southern Greece. Our Volotea flight was due to leave the Marco Polo airport at 6.30AM -an early and cheap flight I had picked to ensure we would get to destination at a reasonable time. 
The top quark is the heaviest known subatomic particle we may call "elementary", i.e. one we describe as a point-like object; it weighs a full 66% more than the Higgs boson itself! Top was discovered in 1995 by the CDF and DZERO collaborations at the Fermilab Tevatron collider, which produced collisions between protons and antiprotons at an energy 7 times smaller than that of the proton-proton collisions now provided by the Large Hadron Collider at CERN.
I am happy to announce here that a session on "Statistical Methods for Physics Analysis in the XXI Century" will take place at the "Quark Confinement and the Hadron Spectrum" conference, which will be held in Thessaloniki on August 28th to September 3rd this year. I have already mentioned this a few weeks ago, but now I can release a tentative schedule of the two afternoons devoted to the topic.
I am spending some time today at the Altarelli Memorial Symposium, which is taking place at the main auditorium at CERN. The recently deceased Guido Altarelli was one of the leading theorists who brought us to the height of our understanding of the Standard Model of particle physics, and it is heart-warming to see so many colleagues young and old here today - Guido was a teacher for all of us.
