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.

One Year in Review

by Tommaso Dorigo

Christmas is coming, and with it a temporary stop of working activities for most of us- but not all, as the world does not stop spinning, nor do electrons in the computers that crunch LHC datasets in search for new physics. As for academics, they leave their offices with piles of articles to review and grant proposals to write, knowing that their mailboxes will not stop filling up during the winter break. But it’s a jolly time nonetheless 😉 Continue reading “One Year in Review”

Things that Decay into Boson Pairs

by Tommaso Dorigo

Writing a serious review of research in particle physics is a refreshing job – all the things that you already knew on that specific topic once sat on a fuzzy cloud somewhere in your brain, and now find their place in a tidily organized space, with clear interdependence among them. That’s what I am experiencing as I progress with a 60-pageish thing on hadron collider searches for diboson resonances, which will appear sometime next year in a very high impact factor journal.

One of the things that the review must cover is a theoretical overview of the models that the searches for these physics processes address. So I thought I would say a few words on this topic here – but bear in Continue reading “Things that Decay into Boson Pairs”

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”

W Mass: Closing In

by Tommaso Dorigo

After a lot of agonizing work on tiny systematic uncertainties, the ATLAS collaboration released in time for the Moriond conference their latest measurement of the W boson mass (in fact the only one so far). The result is in close match with previous determinations, and has a slightly larger error bar than those. So why bother discussing it here ?

There is a reason. The W boson is one of the most important subatomic particles Continue reading “W Mass: Closing In”

Fighting Gender Bias

by Tommaso Dorigo

As the few regulars of this blog know, the AMVA4NewPhysics network has in its genes a strong will to fight for gender neutrality in its areas of operation – research in Particle Physics and Applied Statistics. We started off this endeavour 2.5 years ago by including three women as PI of beneficiary nodes out of a total of eight, which was *almost* good. But their research record was outstanding, too, which helped us getting funded!

So that was easy. What was less easy was to deliver what we promised in our programme – a hiring practice capable of producing a gender-balanced pool Continue reading “Fighting Gender Bias”

Decision Trees, Explained to Kids

by Tommaso Dorigo

Decision trees are one of the many players in the booming field of supervised machine learning. They can be used to classify elements into two or more classes, depending on their characteristics. Their interest in particle physics applications is large, as we always need to try and decide on a statistical basis what kind of physics process originated the particle collision we see in Continue reading “Decision Trees, Explained to Kids”

Anomaly! Now Available As E-Book

by Tommaso Dorigo

Today I would like to mention that my book “Anomaly! Collider Physics and the Quest for New Phenomena at Fermilab” is now available for purchase as E-Book at its World Scientific site.
For the occasional readers and the absent-minded regulars, below I paste a summary of what the book is about, the endorsements it received from distinguished scientists in the field, and a few links to reviews in internet resources. The web site of the book at World Scientific is here. At the WS site you Continue reading “Anomaly! Now Available As E-Book”

New Decay Of Lambda_b Seen By LHCb!

by Tommaso Dorigo

The so-called Lambda_b baryon is a well-studied particle nowadays, with several experiments having measured its main production properties and decay modes in the course of the past two decades. It is a particle made of quarks: three of them, like the proton and the neutron. Being electrically neutral, it is easily likened to the neutron, which has a quark composition “udd”. In the space of quark configurations, the Lambda_b is in fact obtained by exchanging a down-type Continue reading “New Decay Of Lambda_b Seen By LHCb!”

A Slow-Motion Particle Collision

by Tommaso Dorigo

Lubos Motl published the other day in his crazily active blog a very nice new review of “Anomaly! Collider Physics and the Quest for New Phenomena at Fermilab“. The review is authored by Tristan du Pree, a colleague of mine who has worked in CMS until very recently – now he moved to a new job and changed to ATLAS! (BTW  thanks Lubos, and thanks Tristan!)

I liked a lot Tristan’s commentary of my work, and since he mentions with quite appreciative terms the slow-motion description of a peculiar collision I offer in my book, I figured I’d paste that below. But before I do that, let Continue reading “A Slow-Motion Particle Collision”
