Large Hadron Collider Detects Particle Decays: An Statistical Fluke according to CERN’s Research Leader


CERN’s Large Hadron Collider (LHC) is located near Geneva. It is back smashing protons after its two-year upgrade to increase its power. CERN scientists explained the recent confirmation of particles that were expected but were never seen.

The Lost Angeles Times reported the decay structure observed “could help researchers test the limits of the standard model of particle physics and probe unexplained cosmic phenomena, including the existence of dark matter and the dearth of antimatter in the universe.”

“From the scientific standpoint, this is big, heady stuff. All the puzzles of physics could fall into place or they could just remain mysteries based on what we learn from these decays,” LHC researcher Joel Butler of Fermilab said. “This is kind of a fantastic time in physics, where many mysteries might get resolved.”

Though the standard model of particle, physics supports the previously detected particles like Higgs boson, the evidence not substantial enough to explain the nature of dark matter, dark energy, or antimatter. Dark matter is impossible to detect directly. It makes up for considerable part of the mass of the universe and thus, its gravitational effect.

Dark energy is thought to be the power behind the expansion of the universe. Antimatter is thought of to have been created together with matter, however according to normal processes, matter and antimatter should have eliminated each other by now.

The type of particles involved in the revolutionary decay observations are called neutral B mesons; they perform at a rate similar to what the standard model predicted  and they are also decay at a rate nearly four times higher than expected.

Butler stated that the difference could be accredited to the inadequate size of information about the strange performance of B meson. “If that holds up, it will be very interesting, but right now, it’s best explained as a statistical fluke. It’s got our attention, let’s put it that way,” Butler said.

The group will be gathering more data to find out which particle continue to keep up with the standard model and which particle decays. Either the result will sustain or dismiss theories pertaining with supersymmetry. Supersymmetry is a model of particle physics which assumes that each particle has a huger “superparticle” twin, which would decay quickly into more steady and less gigantic particles. Under the supports of supersymmetry, the weightless and most steady of these particles could be the indefinable form of dark matter.

The results were distributed in the journal Nature.
