New, undiscovered charged particles could be produced by the LHC, leaving tracks in CMS that look similar to tracks from Standard Model particles. If the new particle decays to other, unseen new particles inside the CMS tracker, a very striking…

Nowadays, artificial neural networks have an impact on many areas of our day-to-day lives. They are used for a wide variety of complex tasks, such as driving cars, performing speech recognition (for example, Siri, Cortana, Alexa), suggesting…

At the LHC, protons do not collide one at a time. Instead, the protons are combined into bunches, packages of more than 100,000 million (1011) protons. These bunches are then pointed at each other at the four collision points of the LHC. Even when…

When the LHC is sending billions of protons at each other millions of times per second, it’s important to know just how many of them actually are colliding, both so that the LHC can optimize its operations to produce the most collisions possible,…

Soon after 2027, the LHC will enter the high luminosity era, known as HL-LHC, during which it is expected to deliver about 20 times more data than delivered up the end of Run 2. In order to achieve such high luminosity, the LHC is going to use…

2019 is approaching its end with it the first year of the LHC Long Shutdown 2 (LS2),a break that focuses on the upgrade and maintenance of the LHC. It’s been twelve intense months for the growing CMS collaboration that counts 53 member countries.…

Early one morning, residents of the Pathum Wan District of Bangkok were greeted to the rare spectacle of dozens of physicists in formal attire walking the streets of Bangkok on their way to meet Her Royal Highness Princess Maha Chakri Sirindhorn of…

The CMS electromagnetic calorimeter (ECAL) measures the energy of electrons and photons produced in the LHC collisions with extreme precision. It includes, as main active element, 75848 scintillating crystals made of lead tungstate, a material that…

The 2019 edition of the International Conference on Computing in High Energy and Nuclear Physics (CHEP, chep2019.org) was held on 4–8 November in Adelaide (South Australia). The conference organizers, the University of Adelaide, welcomed over 500…

The CMS detector is going through multiple maintenance works during the LHC Long Shutdown 2 (LS2), the first year of which is approaching its end. The beginning of 2019 saw the CMS Tracker Pixel detector extraction that is now stored in a clean room…

The CMS collaboration presented over ten brand-new results in the latest installment of the Quark Matter conference, one of the largest conferences in the field of heavy-ion physics. In heavy-ion physics, the properties of the quark-gluon plasma, a…

With the connection of the final cable on October 4, CMS completed the installation of new on-detector electronics for the Hadron Calorimeter (HCAL) barrel detector. Following a series of upgrades to the electronics of  various HCAL…
