Plasma lenses promise smaller accelerators
An international team has made an advance towards more compact particle accelerators, demonstrating that beams can be focused via a technique called active plasma lensing without reducing the beam qua...
ATLAS observes scattering of vector bosons
The cross-section of longitudinal weak-boson scattering would diverge, resulting in meaningless values, were it not for the exact cancellation due to Higgs-boson contributions.
Data-processing visionary: Paul Kunz 1942–2018
A computing visionary and pioneer, who loved to share his ideas with irrepressible energy.
A giant of experimental particle physics: Leon Lederman 1922–2018
Lederman’s crowning achievement came in 1962 with the co-discovery of the muon neutrino.
Quarks, calorimetry and cosmology: Hans Paar 1944–2018
He helped to create an atmosphere of creative thought and friendliness within every group he was part of.
Suppression of the Λ(1520) resonance in Pb–Pb collisions
Due to their short lifetimes, they decay when the system is still dense and the decay products scatter in the hadron gas, reducing the observed number of decays.
Search for new quarks addresses unnaturalness
Why is the observed mass of the Higgs only 125 GeV?
CMS detects first production of top quark and photon
The predicted cross section for tγj, including the branching fraction, is 81 fb, which corresponds to a few hundred events in the whole dataset.
Sparking the November Revolution: Burton Richter 1931–2018
A major figure in particle physics who shared the Nobel Prize for the co-discovery of the J/ψ meson.
Nobel work shines a light on particle physics
This year’s Nobel Prize in Physics was shared between three researchers for groundbreaking inventions in laser physics. Half the prize went to Arthur Ashkin of Bell Laboratories in the US for his wo...
