![]() The third run is scheduled to last until the end of 2025. "For that, we use specific parts of our hardware that send signals when something looks like it's interesting." It's impossible to keep all that data, so we need to have a strategy to pick the events that we think are interesting," Gonzalez Suarez told Live Science. " produces 1.7 billion collisions per second. So scientists at CERN have improved the automated systems that first process the data and select the most interesting events to be saved and later studied by scientists. But while the LHC experiments will deliver terabytes of data every second, only a fraction can be saved and studied. The LHC's detector upgrades will enable its instruments to gather high-quality data on this new energy regime. The LHC will also smash atoms together more often, which should make it easier for scientists to find uncommon particles that are very rarely produced during collisions. The new upgrades will allow the LHC to smash particles harder than ever before - up to an energy of 6.8 teraelectronvolts, an increase over the previous limit of 6.5 teraelectronvolts – which could enable the LHC to see new types of particles. "These two experiments attempt to solve some of the biggest puzzles in physics, such as the nature of dark matter, the origin of neutrino masses, and the imbalance between matter and antimatter in the present-day universe," Fartoukh told Live Science via email. ![]() 5 sci-fi concepts that are possible (in theory) ![]() ![]() Why a physicist wants to build a particle collider on the moon 'X particle' from the dawn of time detected inside the Large Hadron Collider Yet our universe exists and is mostly matter. In theory, that means they should have annihilated on contact, leaving nothing behind. Matter and antimatter are thought to have been produced in equal amounts at the Big Bang. Such detections will help scientists understand these particles in greater detail than ever before.Īnd they may also address another conundrum. FASER's subdetector, FASERν, and SND will aim to detect high-energy neutrinos, which are known to be produced at the collision site but have never been detected. FASER will use a detector located 1,575 feet (480 meters) from the collision site for the ATLAS experiment, with the goal of collecting unknown exotic particles that can travel long distances before decaying into detectable particles - for instance, potential weakly interacting massive particles that barely interact with matter and could make up dark matter. The upcoming LHC run will also introduce two new physics experiments: the Scattering and Neutrino Detector (SND) and the Forward Search Experiment (FASER). "Maybe there will be a surprise in there." "I'm excited to get data again and see what we can see in the different searches," Rebeca Gonzalez Suarez, a CERN physicist, an education and outreach coordinator for the ATLAS Collaboration and an associate professor at Uppsala University in Sweden, told Live Science. ATLAS will be on the hunt for a proposed left-handed relative to the neutrino called a heavy neutral lepton, according to a statement (opens in new tab) from the ATLAS Collaboration. ![]() In theory, right-handed neutrinos should exist, but no one has ever found an elusive right-handed neutrino, a left-handed antineutrino or an antimatter twin to an ordinary neutrino, for that matter, according to Fermilab (opens in new tab). In addition to other tasks, the ATLAS experiment, the largest particle detector at the LHC, will try to answer a question that has puzzled scientists for decades: Why are all the neutrinos detected so far southpaws? Most particles come in left- and right-handed flavors – which describe how the particles spin and move – and are thought to have antimatter twins – which have the same mass but the opposite electric charge. In the upcoming third run, the collider's upgraded capabilities will focus on exploring the properties of particles in the Standard Model, including the Higgs boson, and hunting for evidence of dark matter. ![]()
