The event display of the ALICE experiment shows an anti-alpha candidate track among the many other particles produced in a Pb-Pb collision (Image: ALICE collaboration) In a recent paper*, the ALICE collaboration has released the measurement of the integrated production yield of the alpha particle as well as of its anti-matter partner, the anti-alpha nucleus, […]
(Image: NASA) The CALorimetric Electron Telescope (CALET) space mission has just released its first results concerning the nature of high-energy cosmic rays. Having docked with the International Space Station (ISS) on 25 August 2015, CALET takes high-precision measurements of the electron energy spectrum from 1 GeV to 20 TeV to also hunt for signatures of […]
Achintya Rao It has been a little over seven (and a half) years since the LHC started delivering collisions to CMS for physics analysis, and just a few days ago we published our 700th research paper. To celebrate this achievement, we thought we would give you a glimpse of seven of several milestone papers CMS […]
Harriet Jarlett The research was conducted with ISOLTRAP, whose beamline is visible here, an experiment at CERN’s nuclear physics facility, ISOLDE (Image: CERN) Scientists at CERN’s ISOLDE facility have found evidence that nickel-78 is doubly magic by examining its nuclear neighbour, copper-79, in research recently published in Physical Review Letters. Nuclei that have specific ‘magic’ […]
At its triennial seminar, the International Committee for Future Accelerators (ICFA) discussed a range of projects that will safeguard the future of accelerator-based particle physics. ICFA is the international body that facilitates international collaboration in the construction and use of particle accelerators for high-energy physics. Every three years, government officials, representatives of the major funding […]
Fractional contributions of the various backgrounds to the total background prediction in each region of the ttH(H→bb) analysis for events with exactly one electron or muon. (Image: ATLAS Collaboration/CERN) The ATLAS collaboration has presented evidence of “ttH production”, a rare process where a pair of top quarks emits a Higgs boson. Observing this process would provide new […]

Matthew Chalmers Measurements of R(D*) from LHCb (green region), BaBar and Belle compared to the Standard Model prediction (red). The measured values from the three different experiments are all higher than the SM prediction, although the statistical significance is low. Two papers published today in Nature review recent flavour measurements from the LHCb experiment that are […]
The fifth annual Large Hadron Collider Physics (LHCP2017) conference was held last week at Shanghai Jiao Tong University, China. This year there were more participants than ever before: 470 people from universities across the globe. ATLAS presented an interesting set of new results exploiting the high statistics of the combined 2015 and 2016 dataset. Selected highlights are […]
