Physicists on CERN's LHCb collaboration say they've observed three new exotic particles - X(4274), X(4500) and X(4700) - and also confirmed the existence of a fourth one, X(4140).
The next generation of cutting-edge accelerator magnets is no longer just an idea. Recent tests revealed that the United States and CERN have successfully co-created a prototype superconducting accelerator magnet that is much more powerful than those currently inside the Large Hadron Collider.
Researchers have recreated the universe's primordial soup in miniature format by colliding lead atoms with extremely high energy in the 27 km long particle accelerator, the LHC at CERN in Geneva.
New collisions could help explain what conditions were like up to a billionth of a second after the Big Bang
China's Circular Electron Positron Collider (CEPC) is expected to be at least twice the size of the world's current leading collider, the Large Hadron Collider.
The ALPHA collaboration at CERN in Geneva has scored another coup on the antimatter front by performing the first-ever spectroscopic measurements of the internal state of the antihydrogen atom. Their results are reported in a forthcoming issue of Nature and are now online.
(PhysOrg.com) -- During the past few years, CERN physicist Dragan Hajdukovic has been investigating what he thinks may be a widely overlooked part of the cosmos: the quantum vacuum. He suggests that the quantum vacuum has a gravitational charge stemming from the gravitational repulsion of virtual particles and antiparticles. Previously, he has theoretically shown that this repulsive gravity can explain several observations, including effects usually attributed to dark matter. Additionally, this additional gravity suggests that we live in a cyclic Universe (with no Big Bang) and may provide insight into the nature of black holes and an estimate of the neutrino mass. In his most recent paper, published in Astrophysics and Space Science, he shows that the quantum vacuum could explain one more observation: the Universe’s accelerating expansion, without the need for dark energy.
The ALPHA experiment has built and preserved a bunch of Antihydrogen atoms for over some 16 minutes (1000 sec.)
This is the first time anti-matter has been created and stored in a stable long-lasting state. It is hoped the breakthrough could help us to understand the composition of the universe.
CERN has kicked off the High Luminosity LHC (Large Hadron Collider) study with a workshop bringing together scientists and engineers from some 14 European institutions, along with others from Japan and the USA. The goal is to prepare the ground for an LHC luminosity upgrade scheduled for around 2020.
Based on extensive feedback from the broader particle physics community on its neutrino time-of-flight measurements presented at CERN on September 23, the OPERA
If it's true, it will mark the biggest discovery in physics in the past half-century: Elusive, nearly massive subatomic particles called neutrinos appear to travel just faster than light, a team of physicists in Europe reports. If so, the observation would wreck Einstein's theory of special relativity, which demands that nothing can travel faster than light.
