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 […

ATLAS results: from precision to rarity

Two recent ATLAS results that showcase the full range of the ATLAS physics potential, from precision to rarity, were shown at LHCP and presented at a recent CERN LHC seminar. A test of the universality of τ and μ lepton couplings in W boson…

Interview with Andrei Linde

Andrei Linde is Harold Trap Friis Professor of Physics at Stanford University and one of the most influential cosmologists of our time. Linde is one of the authors of the inflationary universe scenario, which is gradually becoming the…

A word from the Head of the EP department - June 2020

Dear Colleagues, dear Members of the EP Department and CERN Users, This edition of the newsletter marks the end of the first half of 2020. Since a few months the whole world has been going through an unprecedented crisis, and so has CERN. We were…

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…

LHCb adopts GPUs in Run 3 trigger

The LHCb experiment is currently being upgraded to continue its study of beauty and charm hadrons at a five times higher instantaneous luminosity in LHC Run 3 that is now set to start in 2022. At the increased luminosity, these hadrons are produced…

CLOUD experiment makes its own clouds to study

The Intergovernmental Panel on Climate Change (IPCC) recognizes aerosols (small nanometer to micrometer sized particles suspended in air) as the single biggest source of uncertainty in human-driven climate change. Atmospheric aerosol particles are…

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…
