Measuring the strong coupling constant: from the LHC to FCC-ee
Measuring the strong coupling constant: from the LHC to FCC-ee The latest advances in the measurement of the coupling of the strong interaction were discussed in a recent workshop on “High precision measurements of αs: from LHC to FCC-ee” held at CERN, 12-13 October 2015. The meeting brought together the leading experts in the field

A Timelapse video of CAST
A Timelapse video of CAST The CERN Axion Solar Telescope (CAST) is an experiment to search for hypothetical particles called axions. These have been proposed by some theoretical physicists to explain why there is a subtle difference between matter and antimatter in processes involving the weak force, but not the strong force. If axions exist,

LHC experiments upgraded trigger plans
LHC experiments upgraded trigger plans As the LHC prepares for higher energies and luminosities all four experiments have upgraded their triggering to record data more efficiently and make sure that their detectors are ready to find evidence for new physics. The trigger teams from the experiments describe the changes made between Run1 and Run 2

A word from the organizers of the Summer Student programme
A word from the organizers of the Summer Student programme The Summer Student Programme gives undergraduate students of physics, engineering and computer science the unique possibility to join CERN for 8-13 weeks. It gives the students not only the chance to work on an exciting project, the students can also attend first-class lectures, workshops and

CMS results in Hard Probes 2015
CMS results in Hard Probes 2015 CMS has delivered a comprehensive set of differential RAA measurements, quantifying the jet quenching effect for hard probes of various flavors. Profound suppression of strongly interacting probes in 2.76 TeV PbPb collisions is established with high precision for inclusive charged hadrons, spanning the wide range of transverse momenta from

ATLAS results from lead-lead and proton-lead collision
ATLAS results from lead-lead and proton-lead collision The ATLAS results from PbPb data included a measurement of high-pΤ photons and W mesons, high-precision measurement of jet and charged particle RΑΑ, studies of jet fragmentation, path length dependence of jet quenching, neighbouring jet production and studies of flow and correlations of low pΤ particles. The pPb

LHCb results from proton-lead collisions and prospects for heavy ion interactions
LHCb results from proton-lead collisions and prospects for heavy ion interactions At the 7th edition of the Hard-Probes conference, taking place at McGill University, Montreal, from June 29 – July 3, the LHCb collaboration presented for the first time its plan and potential in heavy ion physics. Beyond the rich programme in flavour physics based

Measurement of J/ψ production cross-sections in pp collisions at 13 TeV
Measurement of J/ψ production cross-sections in pp collisions at 13 TeV At the EPS-HEP 2015 conference in Vienna the LHCb collaboration has presented today the first measurement of the probability to produce a J/ψ meson in proton-proton collisions at 13TeV. Using this measurement they also determined the rate at which beauty quarks are produced at
