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 […]
The LHC normally collides protons into each other. If two protons travelling in opposite directions pass very close to one another within CMS or ATLAS, however, photons radiated from each proton can collide and produce new particles. Precision spectrometers situated on either side of CMS experiment, and a similar project taking shape at ATLAS, will […]
Lead ion collisions (F Ronchetti/CERN) Three decades since the first ultra-relativistic collisions were produced at CERN, the field of heavy-ion physics is still a hot topic. High-energy heavy-ion and proton-proton collisions provide a unique system with which to investigate the dynamics of matter in the early universe and to probe fundamental predictions of quantum chromodynamics. […]
(Image: Daniel Dominguez/ CERN) During the past two years there has been a burst of activity in next-to-next-to-leading order (NNLO) calculations to make sure theory keeps up with experiment. Underpinning the prediction of LHC observables are perturbative computations of cross-sections, and NLO corrections have already been calculated for a large class of these processes relevant […]
The 52nd Rencontres de Moriond conference is taking place in La Thuile, Italy, from the 18 March to 1 April. The first week, which ran until 25 March, was devoted to the theme "Electroweak interactions and unified theories", and the second session is based on the theme of “QCD and high energy interaction”. The four main […]
