Virtual Visit to CMS at CERN (2016)

On February 24, 2016, at 15 hours, 55 students and 5 teachers in Escola Secundária Dr. Júlio Martins (Portuguese high school), made a virtual visit to CMS at CERN.


The activity was promoted by the European Project Inspiring Science Education (ISE), and it was made, for the second time, with a total of five portuguese schools: Escola Secundária Dr. Júlio Martins (Chaves); Escola Secundária Paços de Ferreira (Paços de Ferreira); Escola Secundária de Loulé (Faro), Agrupamento de Escolas Dra. Laura Ayres (Quarteira); Escola Secundária Adolfo Portela (Águeda).
The students saw the control room, the cavern of CMS (Compact Muon Solenoid) experiment, installed in LHC (Large Hadron Collider) and asked some questions to the scientists.
The students made a contact with Portuguese scientists, Pedro da Silva, André David Mendes and José Carlos da Silva, with technical support of Angelos Alexopoulos, Noemi Beni e Zoltan Zsillasi. They drove our students through CMS control room, and explained all the graphics in their computers, to the CMS cavern, 100 meters deep, and they explained all the objects observed, how it works and characteristics.

Virtual Visit to CMS at CERN

On February 25, 2015, at 15 hours, 150 students and 10 teachers in Escola Secundária de Penafiel (Portuguese high school), made a virtual visit to CMS at CERN.

The activity was promoted by the European Project Open Discovery Space (ODS), and it was made, for the first time, with a total of five portuguese schools: Escola Secundária de Penafiel (Penafiel); Escola Secundária Ferreira Dias (Sintra); Escola Secundária José Saramago (Mafra), Agrupamento de Escolas Dra. Laura Ayres (Quarteira); Escola Secundária Adolfo Portela (Águeda).
The students saw the control room, the cavern of CMS (Compact Muon Solenoid) experiment, installed in LHC (Large Hadron Collider) and asked some questions to the scientists.
The students made a contact with portuguese scientists, Pedro da Silva, André David Mendes and José Carlos Silva, with technical support of Angelos Alexopoulos, Noemi Beni e Zoltan Zsillasi. They drove our students through CMS control room, and explained all the graphics in their computers, to the CMS cavern, 100 meters deep, and they explained all the objects observed, how it works and characteristics.



We achieved a total of 553 students in this virtual visit, and it was established a new record of students participating in a same session. All the students were pleased to visit virtually this especial science center.


Some feedback from our students:
Hello teacher, I would like to thank you the opportunity to participate in something unique. For students that study Physics, CERN is the epicenter of investigation and knowledge. I loved the fact that we made contact with scientists and it was so fun how they present the detector and technologies provided by CERN. It was useful to extend the knowledge of tiny world despite the fact that we need such a huge machine, like CMS, to discover that world. To see all of this visit in real time image was exceptional...
Thanks to all, specially people at CERN and our teachers to make this happened.” - André Queirós

"Hello teacher, I'm written this email about our virtual visit to CERN. It was a visit that arises our interest and curiosity to know better CERN and the experiments made by scientist. The simple language used by scientists helps us to understand the experiments, and kept students' attention.
I liked to thank the availability and I hope someday to know CERN even better." - Ana Catarina Moreira

"Hello teacher, I like to thank you for the visit, even virtually, it was very good and educative. I hope to perform another visit, but this time a live one. I was curious on CERN center and LHC detectors, and the explanation of both made by site scientists.
I wish a year full of success and with new discoveries!" - João Pereira.

"Hello teacher, the virtual visit was very interesting, now I understand what happen in there and what scientists do, how do they do it and the level to acquire such performance in science and technology. It was important to see the detector and jobs possibilities to students. Thank you so much for this opportunity" -  Tiago Carvalho

Rare particle decay detected at LHC

Protons collide in the CMS detector, producing a Bs particle that 
decays into two muons (red lines) in this event display from 2012 (Image: CMS)
New results to be presented today at the European Physical Society's High Energy Physics conference (EPS-HEP 2013) in Stockholm, Sweden, have put the Standard Model of particle physics to one of its most stringent tests to date. The CMS and LHCbexperiments at CERN’s Large Hadron Collider (LHC) will present measurements of one of the rarest measureable processes in physics: the decay of a Bs (pronounced B-sub-s) particle into two muons.
The new measurements show that only a handful of Bs particles per billion decay into pairs of muons. Because the process is so rare, it is an extremely sensitive probe for new physics beyond the Standard Model. Any divergence from the Standard Model prediction would be a clear sign of something new.
Both experiments will present results to a very high level of statistical significance (over 4 sigma for each experiment). These results are in good agreement with the Standard Model.

CMS gaves a lot of particle collision data

Credit: CERN

"Datasets are the currency of physics. As data accumulate, measurement uncertainty ranges shrink, increasing the potential for discoveries and making non-observations more stringent, with more far-reaching consequences. In collider experiments, the amount of data is measured by the total number of collisions observed and the rate of those collisions, called the luminosity. In 2011, the Large Hadron Collider (LHC) produced more collisions than scientists dared to expect, breaking the world record luminosity in April and then continuing to grow seven-fold. By the end of the proton collision run in November, 240 million protons were colliding each second."


CMS Particle Detector
The LHC smashes groups of protons together and very close to the speed of light: 40 million times per second and with seven times the energy of the most powerful accelerators. When the collisions happens some of its energy is turned into mass and previously unobserved, short-lived particles – which could give clues about how Nature behaves at a fundamental level - fly out and into the detector.


The Physics Results
All the Physics results can be found here.

CMS is a general-purpose experiment with sub-groups producing results for many different topics including:
