Among them , there is a special particle decomposition that only happens a fistful of metre for every trillion . The particle in question is known as akaon . While the proton and neutrons at the center of the atom that make us are composed of three quarks , kappa-meson are instead composed of two . These particles are create in an throttle valve but they are also raining down on all of us as we speak in the form of cosmic rays . physicist are specially concerned in these kaons because the irritating little particles have been take in violate several physics conservation law – and that ’s always exciting .
The hope was that in the highly uncommon decays , some effect of exotic natural philosophy will become apparent . TheNA62 experimentat CERN depend at incisively that and they now report on the analysis of two years ' worth of information . The team did indeed see this extremely rare kaon decay , where the kaon turns into a pion ( another two - quark particle ) and two neutrinos .
Out of 6 trillion kaon decays , the team discover 17 of these particular events . The results were measured to a 30 percent precision and are generally coherent with the Standard Model of Particle Physics .
“ This kaon decline process is called the ‘ golden channel ’ because of the compounding of being both extremist - rarified and excellently predicted in the Standard Model . It is very difficult to capture and holds real promise for scientists look for newfangled physics , ” Professor Cristina Lazzeroni , a speck physicist at the University of Birmingham and interpreter for NA62 , say in astatement .
“ This is the first time we have been capable to obtain significant experimental evidence for this decay process . It is an exciting consequence because it is a fundamental pace towards capturing the exact measurement of the decay and identify possible deviations from the Standard Model . ”
The collaboration is planning to collect more data from next class until 2024 . The experiment is being upgraded and more information will be available . The magnanimous data rig will hopefully labor the precision to around 10 percent . Currently , it is unknown if this will be enough to see a deviation from the Standard Model , but research worker are already work on ways to push that precision even further and catch up with more glimpses of what ’s beyond our aperient possibility .
