Last week I attended an interesting course about Supersymmetry theory (SUSY) at CP3. The course was meant to be an introduction to SUSY, but in fact it treated this theory in deep detail from a mathematical point of view. It developed all the (endless!) calculations from which the supersymmetric lagrangian can be inferred. Continue reading “Introdution to SUSY in 5 minutes!”
By now the adrenaline from the announcement of the first direct detection of gravitational waves has subsided, and we can discuss the particulars of the observation. Here, I’ll try to describe the state of the detectors, answer some questions about the analysis methods, and highlight a few points about the detection that might have gotten lost in the excitement.

On March 3rd the AMVA4NewPhysics network will host an event you should not miss if you happen to be in Venice or the whereabouts. The event is titled “Suonando con le particelle” – playing music with particles, and it takes place in the enchanting hall called “Sala della Musica” of the Ca’ Sagredo Hotel in Venice.
One of the things I like the most when I do data analysis is to use pure thought to predict in advance the features of a probability density function of some observable quantity from the physical process I am studying. By doing that, one can try one’s hand at demonstrating one’s understanding of the details of the physics at play. Continue reading “B Fraction Challenge”
Hi there! It’s been more than two months since I started my PhD and officially joined the AMVA4NewPhysics network by signing an employment contract with the INFN. It was a quite intense period work-wise: getting up to speed with my project, working on analyses’ codes, writing blog posts, starting some PhD courses, getting to know my co-workers, presenting in a workshop and much more.

While working with LHC data we encounter the problem of a high-dimensional observed space as we deal with about 40 variables. Of course some of them are correlated, dependent or even made out of others. From one side, having such an abundance of data gives us a lot of information, but it has also some disadvantages about which I want to write in this article. Continue reading “On the need for dimension reduction”
A Sino-Italian workshop on Applied Statistics was held on February 2 at the Department of Statistical Sciences of the University of Padova. The organizers were Alessandra Brazzale and Alessandra Salvan from the Department of Statistical Sciences, and Giorgio Picci from the “Confucius Institute”.
