The last CMS week of the year was held two weeks ago, summarizing all the upgrades and changes that happened in 2017, but also the plans of the groups for 2018. Since my service work concerns the L1 muon trigger performance, I was asked by the data performance group conveners to give a talk about the muon trigger algorithms and the improvements that happened last year. Continue reading “The L1 muon trigger algorithms”
So, it’s been a while since my last post, apologies for that, but the summer has been both busy and eventful, so let me summarise what’s been happening. Continue reading “Summer activities at LIP-Lisbon”
Today I had a very full day. It started with a working meeting (an informal meeting of the people working on some analysis) for planning how to improve the EWkino analysis (one of the searches for new physics we are involved in) with the new data CMS is taking. I then went on to the UniOvi CMS group weekly meeting, in which we all meet in the large common office (plus some people connected in videoconference from CERN) to discuss the various topics the group is involved it. Let me delay to another occasion my rant on the amount of CMS meetings we are subjected to!
Then, after some quick and frenetic coding work, I Continue reading “«Es chulo», or «This night, I almost cried»”
Continuing on from my last post, in which I described part of the service work I am doing in the CMS experiment, I’ll now give an overview of the second project I work on, which takes place in the context of the CT-PPS sub-detector of the CMS experiment.
CT-PPS, located on both sides of the main bulk of CMS some 200 metres from the interaction point, stands for CMS-TOTEM Precision Proton Spectrometer. The experiment is a joint project Continue reading “CT-PPS Detector Alignment”
Both the CMS and ATLAS collaborations are pretty vast, with around 5000 qualified scientist between them, and even more members working towards qualification. Everyone listed as ‘qualified’ will be listed as an author on any publication the collaboration produces, regardless of who actually did the major work for the analysis. Continue reading “Tau Identification At CMS With Neural Networks”
The work named “Attimo” (or “instant” in English) was produced by Nicolò Doglioni, Filippo Dorigo, and Zeno Pogaznic from Liceo “Benedetti”. They were impressed by the pictures of the CMS detector and its components, and they decided to try and capture the symmetry of the detection elements in a way that makes it only apparent if you happen to end up in the correct line of sight.
The attached pictures show the construction, made of coloured wood Continue reading “Art & Science 27: Instant”
Many of the high school students participating in the Art & Science contest in Venice took inspiration from the pictures of LHC collisions creating the Higgs boson, and attempted to produce a three-dimensional realization of what physicists only realize on their computer screens.
The work shown here, produced by Eleonora Perale and Camilla Longo, is probably the one of the lot that reproduces with most care one of the Continue reading “Art & Science 21: The Boson’s Tracks”
An assembly of wooden circles installed one inside the other, containing plastic rods of different colour, is the work by Alice Giambini, Matteo Quaglio, and Olga Pintus of Liceo “Marco Foscarini”.
The students took inspiration from the fact that the CMS detector is composed of several layers, each of which has the main function of detecting and measuring a different kind of particle. So they reproduced schematically the concept by having different “cycles” connected to different particle tracks (the plastic rods). These Continue reading “Art & Science 10: RiveliAMO”
The fifth artwork presented here for the series “Art & Science” (see previous posts for more details of this art contest, connected to the EPS 2017 conference) is actually titled “Toward the Boson and Beyond”. It is the result of collaboration of three students of the Liceo Marco Foscarini in Venice: Chiara Chiapatti, Micol Zhu, and Ludovica Violato. The students designed and realized a way to imagine a particle collision using a telescope. You thus get to literally immerse yourself in the beam pipe Continue reading “Art & Science 5: From Galileo to the Higgs Boson”
