scientists working with the large hadron collider lhc near geneva have discovered three particles

scientists working with the large hadron collider lhc near geneva have discovered three particles that have never been seen before the european nuclear research center cern which built the lhc recently announced the discovery the 27 kilometer long lhc at cern is the machine that found the higgs boson particle this particle along with its linked energy field is thought to be important to the formation of the universe after the big bang 13.7 billion years ago cern says the lhc works by smashing two beams together and using special devices to record the results the two beams inside the lhc are meant to collide or hit each other at four places around a ring there are four particle detectors at these collision spots they are known as atlas cms alice and lhcb atlas and cms surround the whole collision point with an enclosed detector cern's website says the lhcb experiment uses sub-detectors to study forward particles these are particles thrown forward by the collision in one direction the first sub detector is close to the collision point with the others following every 20 meters the lhcb working group observed a new kind of pentaquark and the first ever pair of tetra quarks the findings presented recently at cern on july 5th add three members to the list of new hadrons found at the lhc the research will help physicists better understand how quarks connect or bind together to make composite particles quarks are particles that usually combine in groups of twos and threes to form hadrons such as the protons and neutrons that make up atomic nuclei more rarely however they can also combine into four cork and five quark particles these are called tetra quarks and pentaquarks lhcb spokesperson chris parks described the new particles in a statement finding new kinds of tetra quarks and pentaquarks and measuring their properties will help theorists develop a unified model of exotic hadrons exotic is a term that means unusual parkes said the exact nature of these exotic particles was unknown he added that the new discoveries will also help scientists better understand already discovered hadrons physicist niels tuning said in a statement that the more careful studies we perform the more kinds of exotic hadrons we find tuning added we're witnessing a period of discovery similar to the 1950s during that time new subatomic particles were being discovered which led to new ideas about subatomic physics
