The unprecedented energy of proton collisions at the LHC could be what scientists need to find a possible substructure for subatomic particles The Standard Model of particle physics tells us what elementary particles make up matter in the universe. As far as we know, the particles in the Standard Model are the basic building blocks of matter […]
The ATLAS and CMS collaborations presented their latest results on new signatures for detecting the Higgs boson at CERN’s Large Hadron Collider This media update is part of a series related to the 2020 Large Hadron Collider Physics conference, which took place from 25 to 30 May 2020. Originally planned to take place in Paris,
The CMS detector uses a huge solenoid magnet to bend the paths of particles from collisions in the LHC The Compact Muon Solenoid (CMS) is a general-purpose detector at the Large Hadron Collider (LHC). It has a broad physics programme ranging from studying the Standard Model (including the Higgs boson) to searching for extra dimensions and particles that could make up dark matter. Although it
The ‘Total, elastic and diffractive cross-section measurement’ experiment studies particles thrust forward by collisions in the LHC When protons meet head-on at the Large Hadron Collider (LHC), the collisions provide a micro-laboratory to investigate many phenomena, including the protons themselves. This is the physics that the TOTEM experiment is designed to explore, by taking precise measurements of protons as
Background The current standard for definitive diagnosis of COVID-19 is the real-time reverse transcriptase-polymerase chain reaction (RT-PCR). While this is a highly sensitive and specific test for COVID-19, it does not measure the severity nor progress of the associated lung disease. Significance of CERN Technology/MARS imaging could help COVID-19 treatment monitoring and drug development Mars technology
Why is gravity so much weaker than the other fundamental forces? A small fridge magnet is enough to create an electromagnetic force greater than the gravitational pull exerted by planet Earth. One possibility is that we don’t feel the full effect of gravity because part of it spreads to extra dimensions. Though it may sound

CERN physicists collide heavy ions to free quarks – recreating conditions that existed in the universe just after the Big Bang or a few millionths of a second, shortly after the Big Bang, the universe was filled with an astonishingly hot, dense soup made of all kinds of particles moving at near light speed. This

The ALICE, CMS and LHCb collaborations present new measurements that show how particles containing charm quarks can serve as “messengers” of hadrons and the quark–gluon plasma, carrying information about these forms of matter The Xc1(3872) hadron, which contains charm quarks, could be a pair of two-quark particles loosely bound together. (Image: CERN) This media update

Cosmic-ray data collected by the AMS detector on the International Space Station again challenge conventional theory of cosmic-ray origin and propagation Ever since astronauts attached the 7.5 tonne AMS detector to the International Space Station in May 2011, the space-based magnetic spectrometer, which was assembled at CERN, has collected data on more than 150 billion cosmic rays
Cosmic rays throw up surprises, again Read More »
The Antiproton Decelerator (AD) is a unique machine that produces low-energy antiprotons for studies of antimatter, and “creates” antiatoms. The Decelerator produces antiproton beams and sends them to the different experiments. A proton beam that comes from the PS (Proton Synchrotron) is fired into a block of metal. These collisions create a multitude of secondary
