Some call it revolutionary, some ground-breaking as a new calculation technique has been developed while studying the decay of subatomic particles called Kaons that has the potential to challenge one of the most famous theory of all time — Big Bang Theory, the theory which tells us about the formation of our universe. Scientists believe that with the new method they can get precise experimental values like never before, and then compare it with the theoretical value and any difference occurred will be at the stakes of fundamental principles of Physics.
Kaons are denoted by letter K in particle Physics. Kaons have proved to be a copious source of information on the nature of fundamental interactions since their discovery in cosmic rays in 1947. They were essential in establishing the foundations of the Standard Model of particle physics, such as the quark model of hadrons and the theory of quark mixing. Kaons have played a distinguished role in our understanding of fundamental conservation laws: CP violation, a phenomenon generating the observed matter–antimatter asymmetry of the universe, was discovered in the kaon system in 1964. Moreover, direct CP violation was also discovered in the kaon decays in the early 2000s.
Christopher Sachrajda from the University of Southampton has devised the first ever calculation of how the behaviour of kaons differs when matter is swapped out for antimatter, known as direct “CP” symmetry violation. If the results obtained from the calculations do not match the experiment then it will be evident that what we have known for so long was wrong and some unknown phenomenon is involved in the Standard Model.
However, at present the calculations do not differ from theoretical results, but scientists are optimistic and believe that with the precision of the new technique, calculations will improve by several folds and future experimental values can differ from the theory.
The study was published in the Physical Review Letters.
