I am the scientific coordinator of the AMVA4NewPhysics network. As a member of the CMS experiment at CERN I do research in fundamental physics. I am also an editor of the scientific journal "Reviews in Physics" by Elsevier.

A Trivial Two-Mover

by Tommaso Dorigo

My activity as a chessplayer has seen a steady decline in the past three years, due to overwhelming work obligations. To play in chess tournaments at a decent level, you not only need to be physically fit and well trained for the occasion, but also have your mind free from other thoughts. Alas, I have been failing miserably in the second and third of the above requirements. So I have essentially retired from competitive chess, and my only connection to the chess world is through the occasional 5-minute blitz game over the internet.

Recently a friend pointed me to a site, chess24.com, which has a rather nice interface. I soon started to play a few games per week there, realizing that my strength in quick games has not decreased that much. So I occasionally Continue reading “A Trivial Two-Mover”

What is Statistical Significance?

by Tommaso Dorigo

Yesterday, October 20, was the international day of Statistics. I took inspiration from it to select a clip from chapter 7 of my book Anomaly! Collider physics and the quest for new phenomena at Fermilab which attempts to explain how physicists use the concept of statistical significance to give a quantitative meaning to their measurements of new effects. I hope you will enjoy it….

As we near the discussion of the discovery of the top quark, we need to make a digression to explain an important concept used by particle physicists to measure the level of surprise of an observation, i.e., how much are data at odds with a hypothesis. In a nutshell, the statistical significance of an observed Continue reading “What is Statistical Significance?”

The Physics of Vector Boson Pairs

by Tommaso Dorigo

At 10:00 AM this morning, my smartphone alerted me that in two months I will have to deliver a thorough review on the physics of boson pairs – a 50 page thing which does not yet even exist in the world of ideas. So I have better start planning carefully my time in the next 60 days, to find at least two clean weeks where I may cram in the required concentration. That will be the hard part!

Because of that, rather than an article about things that I know about boson pairs, this is a post about things I do not know well enough now, but on which my knowledge will see a rapid expansion in the near future. Don’t get me wrong: I know the matter, from the history of research in this interesting sub-field Continue reading “The Physics of Vector Boson Pairs”

AMVA4NewPhysics: A Success Story

by Tommaso Dorigo

As I write this, I have on my desk a pile of brochures that INFN and the University of Padova Department of Physics and Astronomy have produced in the context of the program “Europe in my region”.

Thanks to the work, among others, of our press office coordinator Sabine Hemmer, these brochures are real nice booklets in the end. They will be distributed during the “Researchers’ Night” next Friday, September 29, in the context of the large number of initiatives that will take place in Padova – and to which will contribute the members of our network Martino dall’Osso and Pablo de Castro, who will man the INFN stand in the center of Padova.

What do these brochures contain? They describe the dozens of European Projects and Research in Physics and Astronomy that is partly funded by EU initiatives. Each main project takes one page – so AMVA4NewPhysics Continue reading “AMVA4NewPhysics: A Success Story”

A Narrow Escape

by Tommaso Dorigo

If I am alive, I probably owe it to my current very good physical shape.

That does not mean I narrowly escaped a certain death; rather, it means that if I had been slower there are good chances I would have got hit by lightning, under arduous conditions, at 4300 meters of altitude.

So, after this dramatic introduction, I hope I have hooked as many of you as possible, and I can start from the beginning the tale of what was meant to be a half-day excursion with no particular ambitions. I am spending a week in Quito, Ecuador, where I have been lecturing graduate students in astro-particle Continue reading “A Narrow Escape”

Physics Comes From Φύσις

by Tommaso Dorigo

This week I am in Pisa, where I have spent three days to discuss the status and the funding of accelerator-based experiments within the “first national scientific committee” of INFN. Yesterday all coordinators also met for dinner in a good fish restaurant. The discussion never departed much from physics, but it was certainly more relaxed and casual.

One thing that I heard reported by a colleague who has the pulse of public engagement in INFN was that the last “N” in my institute’s acronym causes sometimes a preconceived negative attitude in laypersons who hear Continue reading “Physics Comes From Φύσις”

Muon G-2: The Anomaly That Could Change Physics

by Tommaso Dorigo

Do you remember the infamous “g-2” measurement ? The anomalous magnetic moment of the muon has been for over a decade in the agenda of HEP physicists, both as a puzzle and as a hope for good things to come.

Ever since the Brookhaven laboratories estimated the quantity at a value over 3 standard deviations away from the equally precise theoretical predictions, the topic (could the discrepancy be due to new physics??) has been commonplace in dinner table conversations among HEP physicists.

Similarly, no self-respected “global fit” of standard model observable quantities or scan of allowed parameter space of supersymmetric theories Continue reading “Muon G-2: The Anomaly That Could Change Physics”

Workshop in Oviedo

by Tommaso Dorigo

For the first time, all the 10 Early-Stage Researchers hired by our ITN network got together, to attend the fourth all-network workshop. This was organized by the Outreach Officer Pietro Vischia in the University of Oviedo. Along with the network workshop, a Roostats tutorial is taking place as we speak in the Facultad de Ciencias.

It was very nice to see these young women (4) and men (6) showcasing their recent results on a number of attractive and cutting-edge topics Continue reading “Workshop in Oviedo”

Practical Tools of the Improvised Speaker

by Tommaso Dorigo

Yesterday I visited the Liceo “Benedetti” of Venice, where 40 students are preparing their artwork for a project of communicating science with art that will culminate in an exhibit at the Palazzo del Casinò of the Lido of Venice, during the Continue reading “Practical Tools of the Improvised Speaker”
