It is 20 years since the discovery that the expansion of the universe is accelerating, yet physicists still know precious little about the underlying cause. In a classical universe with no quantum effects, the cosmic […]

DESY chooses a new director Wim Leemans of Berkeley Lab in the US has been appointed director of DESY’s accelerator division, effective from 1 February. A prominent leader in the development of plasma accelerators, Leemans was […]

The electromagnetic field of the highly charged lead ions in the LHC beams provides a very intense flux of high-energy quasi-real photons that can be used to probe the structure of the proton in lead–proton […]

In 2007, while studying archival data from the Parkes radio telescope in Australia, Duncan Lorimer and his student David Narkevic of West Virginia University in the US found a short, bright burst of radio waves. […]

How beauty leads physics astray Lost in Math – How beauty leads physics astray, by Sabine Hossenfelder, Basic Books In Lost in Math, theoretical physicist Sabine Hossenfelder embarks on a soul-searching journey across contemporary theoretical particle […]

People and things Professor Werner Heisenberg died on 1 February 1976. One of the great figures in physics, he was amongst the most active and influential scientists who worked for the creation of CERN. Born in […]

One hundred and fifty years since Dmitri Mendeleev revolutionised chemistry with the periodic table of the elements, an international team of researchers has resolved a longstanding question about one of its more mysterious regions – […]

One of the biggest challenges for the CMS collaboration during LS2 is to prepare its detector for the massive future installations necessary for the HL-LHC.

New wheel-shaped detectors that allow a better trigger and measurement capability for muons are among numerous transformations taking place to maintain the ATLAS physics programme into Run 3 and beyond.

New gravitational-wave events The LIGO and VIRGO collaborations have detected four new gravitational-wave events, bringing the total number of observed events since the first detection in 2015 to 11. Ten of these events are from […]

The discovery of the Higgs boson at the LHC in the summer of 2012 set particle physics on a new course of exploration. While the LHC experiments have determined many of the properties of the […]

Rocio Perez-Ochoa from Spain has a PhD in experimental particle physics and, following a stint in quantitative finance, now runs a company that distributes life- improving products in rural Kenya. Rocio is a member of the CERN Alumni Network:

One of the most fascinating particles studied at the LHC is the top quark. As the heaviest elementary particle to date, the top quark lives for less than a trillionth of a trillionth of a […]

Throughout LHC Run 2, LHCb has been flooded by b- and c-hadrons due to the large beauty and charm production cross-sections within the experiment’s acceptance. To cope with this abundant flux of signal particles and […]

Going from the LHC to a 100  km-circumference supercollider is a daunting challenge, but the community has made similar jumps in the past – and the future of fundamental exploration is at stake.

In our current understanding of the energy content of the universe, there are two major unknowns: the nature of a non-luminous component of matter (dark matter) and the origin of the accelerating expansion of the […]

FACET-II, a new facility for accelerator research at SLAC National Accelerator Laboratory in California, has produced its first electrons. FACET-II is an upgrade to the Facility for Advanced Accelerator Experimental Tests (FACET), which operated from […]

The European Committee for Future Accelerators is assessing individual recognition in large collaborations, not just for the benefit of early-career researchers but for the field as a whole.

The last few years have seen an explosion of original ideas concerning whether the universe is “natural” or not, and the LHC has brought the issue into sharp focus. But we’re only at the beginning of our understanding, says theorist Nathaniel Craig.

The ALICE experiment is being tuned up to make even more precise measurements of the quark–gluon plasma and other extreme nuclear systems.
