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

ATLAS results: from precision to rarity
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 decays from tt̅ events [1]

Interview with Andrei Linde
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 standard paradigm of modern cosmology, replacing the previous versions of the big bang

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

LHCb adopts GPUs in Run 3 trigger
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 so abundantly that selections based

CLOUD experiment makes its own clouds to study
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 important as they can cool the climate by i) reflecting sunlight and ii) by

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
