CERN Accelerating science

Newsletter Articles

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…

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…

With COMPASS-II CERN enters in the exploration of a new territory: the structure of the proton in multiple dimensions. While COMPASS-I primarily studied the distribution and polarisation of quarks and gluons in the nucleon as a function of the…

In August the ALICE experiment published a precise measurement of the difference between ratios of the mass and electric charge of light nuclei and antinuclei produced during heavy-ion collisions at the LHC. The article published in the journal…

Mössbauer spectroscopy (MS) is named after Rudolf L. Mössbauer (1929-2011) who found the effect in 1957 and was awarded the Nobel Prize in Physics for his discovery in 1961. MS makes use of recoilless nuclear resonance fluorescence of gamma rays…

Data Quality Monitoring (DQM) is an important aspect of every high-energy physics experiment. In the era of LHC, when the detectors are extremely sophisticated devices, an online feedback on the quality of the data recorded is needed to avoid taking…
