Extremely rare decays from sub-atomic particles have been detected by the Large Hadron Collider that confirms the predictions of the Standard Model which is a theory that explains the origin of the building blocks of forces found in the universe.

For more than 30 years, scientists are in the quest for this rare evidence emerging from the decay process that involve particles called neutral B mesons.

These recent observations conducted at the LHC which is also the biggest particle accelerator on the planet near Geneva, Switzerland presented that neutral B mesons decayed into muons which are denser cousins of electrons.

In 2012, LHC scientists had a major breakthrough when they announced the discovery of the Higgs boson particle also known as the "God particle" which is a pivotal, fundamental part in the Standard Model of Physics that gives other particles mass.

These new results were conducted by the team lead by Marc-Olivier Bettler from the European Organization for Nuclear Research (CERN).

According to Chris Parkes from the University of Manchester who is a member of the LHCb detector team at the LHC, particle physics is dictated by a current theory called the Standard Model. This theory is proven to be successful that has already been accomplished with the Higgs boson particle and now, all the particles in this theory is now known.

However, questions are still yet to be answered about finding new evidence for newer particles not involved and produced in the Standard Model, he adds.

By measuring these rare decay processes like this latest one, this method can also become an effective way to search for the effects of new particles. Parkes also believes that these new particles can enhance the obsevational rate where the rare decay process is currently being observed.

Now, if the decay continues at the predicted rate, this can allow physicists to make possible extensions of the current theory.

According to co-member Tara Shears of the University of Liverpool, the LHC is the essential guide to see further into the universe by seeing shadows that new physics have cast over already known particles.

These new findings are detailed in the journal Nature.
