The most powerful particle accelerator in the world, CERN's Large Hadron Collider (LHC), is getting up to speed again after its annual winter break. After a switch-on in March and a period of fine-tuning, operators are ramping-up ...

(Phys.org) -- New research, led by University of Warwick physicist Dr Kareem Osman, has provided significant insight into how the solar wind heats up when it should not. The solar wind rushes outwards from the raging inferno ...

Cosmic rays are particles from outer space, typically protons, travelling at almost the speed of light. When the most energetic of these particles strike the atmosphere of our planet, they interact with atomic nuclei in the ...

Jets are the experimental signatures of quarks and gluons produced in high-energy processes such as head-on proton-proton collisions. As quarks and gluons have a net colour charge and cannot exist freely due to colour-confinement, ...

Proton collisions in the Large Hadron Collider often result in the production of "jets" of particles. These jets are a key element in the measurement of many processes, such as the decays of Higgs bosons or other exotic particles. ...

Last week at the 52nd Rencontres de Moriond EW in La Thuile, Italy, the LHCb experiment presented the results of an unprecedented and unusual study. Instead of the usual proton-proton collisions, this time the LHCb detector ...

Roughly once a year, the smallest Large Hadron Collider (LHC) experiment, LHC-forward (LHCf), is taken out of its dedicated storage on the site near the ATLAS experiment, reinstalled in the LHC tunnel, and put to use investigating ...

In particle physics, a jet is a shower of collimated particles generated by a highly energetic quark or gluon. In a lead-lead collision, jets must traverse through quark gluon plasma, altering their energy, track and consistency.

Even in ancient Greece, philosopher Aristotle tried to sum up all the ways that water can behave. Now, about 2,400 years later, two Imperial College London scientists, using laser-flash photography of microscopic droplet-particle ...
