Time will tell whether the LHC and its detectors, with their improved capabilities, can provide a first glimpse of physics beyond our current understanding.” “Today’s news is just the beginning of an exciting few years, as physicists at CERN harness the power of the upgraded machine and vast detectors to push the frontiers of knowledge. Professor Mark Thomson, STFC Executive Chair and particle physicist, said: “The hard work of many highly-skilled scientists and engineers in the UK has been vital to get to this point. The UK’s contributions to the upgrade are worth more than £25 million, funded by the Science and Technology Facilities Council (STFC). University of Manchester physicists continue to contribute to many ongoing CERN-related projects and over the weekend Professor Dame Nancy Rothwell, President and Vice-Chancellor, visited the site and met with some of the scientists involved. Scientists from The University of Manchester have long held leading roles in CERN through the ATLAS and LHCb projects. The LHC will now run around the clock for close to 4 years at the record energy of 13.6 trillion electronvolts (TeV).Īs part of the international effort, UK teams have led a series of vital work packages to improve the performance of each of the LHC’s four main instruments, as well as work on the beam itself. The LHC machine and its injectors had previously been recommissioned to operate with new higher-intensity beams and increased energy.īeam operators have now announced the beam is stable and ready to start taking data to be used for science. The beam began circulating in April, after years of upgrades and maintenance work to make it even more powerful. Using the upgraded machine, it is hoped that the LHC experiments will provide new insights into the dominance of matter over antimatter and the nature of dark matter. Ten years since the discovery of the Higgs Boson particle was announced to the world, the LHC is today moving ahead to the next stage of fundamental physics experimentation to help humanity’s understanding of the fundamental particles and forces that govern the Universe. These will enable us to test the Standard Model of particle physics in unprecedented ways but they will surely also lead to surprising and unexpected discoveries.” Professor Chris Parkes from The University of Manchester currently serves a three year term as Spokesperson of the LHCb experiment and said: “We are excited to see the research, development and construction efforts from the past 15 years turn into measurements of unprecedented precision. Staff and PhD students in the Particle Physics Group at The University of Manchester play a central role in both the ATLAS and LHCb experiments (two of the four experiments collecting data from the LHC) from research and development of cutting-edge particle detectors for these experiments to multiple leadership roles in international research groups. Today (July 5) marks the start of the accelerator's third run of data-taking for physics at the facility on the French-Swiss border, near Geneva. The Large Hadron Collider (LHC) at CERN is now equipped with new detector systems and enhanced data acquisition and computing structures which are now all operational. We're creating 'particle zoo 2.0'.The world’s most powerful particle accelerator is ready to start delivering proton collisions to experiments at a record-breaking energy level after three years of upgrade and maintenance work. "We're witnessing a period of discovery similar to the 1950s, when a 'particle zoo' of hadrons started being discovered and ultimately led to the quark model of conventional hadrons in the 1960s. "The more analyses we perform, the more kinds of exotic hadrons we find," physicist Niels Tuning said in a statement. More rarely, however, they can also combine into four-quark and five-quark particles, or tetraquarks and pentaquarks. Quarks are elementary particles that usually combine in groups of twos and threes to form hadrons such as the protons and neutrons that make up atomic nuclei. ![]() They will help physicists better understand how quarks bind together into composite particles. ![]() Now scientists at CERN say they have observed a new kind of "pentaquark" and the first-ever pair of "tetraquarks", adding three members to the list of new hadrons found at the LHC. The 27 kilometre-long (16.8 mile) LHC at CERN is the machine that found the Higgs boson particle, which along with its linked energy field is thought to be vital to the formation of the universe after the Big Bang 13.7 billion years ago. GENEVA, July 5 (Reuters) - Scientists working with the Large Hadron Collider (LHC) have discovered three subatomic particles never seen before as they work to unlock the building blocks of the universe, the European nuclear research centre CERN said on Tuesday.
