CMS restarts and continues working under Covid-19 conditions
CMS restarts and continues working under Covid-19 conditions One of the major objectives of CMS for LS2 is an early phase-2 electronics upgrade of the Cathode Strip Chambers (CSC), located on all three endcap disks, and the installation of one layer of triple Gas Electron Multiplier Chambers (GEM) on the first endcap disk. This work

CERN experiments find first evidence for rare Higgs boson decay
CERN experiments find first evidence for rare Higgs boson decay The strength of the interaction between the Higgs field and a particle determines the mass it obtains from the Higgs and it is a mystery why the interaction strength is different for different particles. This puzzle is exacerbated as the leptons, quarks and neutrinos appear

How to search for new physics without knowing about it?
How to search for new physics without knowing about it? BSM searches at the LHC increasingly profit from ML techniques since this approach allows more general searches that minimise the probability of missing evidence of new physics. Very recently, the ATLAS collaboration has published a novel approach [1], based on weakly unsupervised ML techniques, to

LHC experiments ramp-up activities
LHC experiments ramp-up activities Around the world,research centres, laboratories and universities have closed as a response to the COVID-19 pandemic — forcing an increasing number of researchers to work from home. Researchers teleworking coordinated with colleagues who had to continue working in the lab to ensure continuation of critical activities as well as a smooth

CMS tunes in searches for new physics
CMS tunes in searches for new physics The CERN LHC has produced proton-proton collisions at an unprecedented center of mass energy of 13 TeV since 2015, providing an excellent opportunity to search for new phenomena in regions that were previously inaccessible to collider experiments. While the standard model (SM) of particle physics is well established

CMS weighs in for the top quark
CMS weighs in for the top quark The top quark has a special position in the zoo of elementary particles, being the heaviest as well as one of the rarest fundamental particles ever sighted. With a mass of about 173 GeV, it has 40 times the mass of its partner, the bottom quark and is

Exploring new ways to see the Higgs boson
Exploring new ways to see the Higgs boson The ATLAS and CMS collaborations presented their latest results on new signatures for detecting the Higgs boson at CERN’s Large Hadron Collider. These include searches for rare transformations of the Higgs boson into a Z boson – which is a carrier of one of the fundamental forces

New physics opportunities with heavy-ion collisions at the LHC
New physics opportunities with heavy-ion collisions at the LHC The LHC is the latest scientific tool in a long line of increasingly sophisticated machines built over the last 70 years to study the inner workings of our Universe and the laws governing its microscopic structure and evolution. Decades-long experimental and theoretical efforts have given rise
