It is a tragic day in the world of particle physics. Over four months ago I wrote the article Possibility Of New Particle and promised a follow up when new information arose. And here it is, hot off the presses from the International Conference on High Energy Physics (ICHEP) from earlier today. It appears that the irregular extra photons produced, that were speculated to show a new particle outside of the standard model, were just part of a anomaly and have not been represented again in the most recent data. Two independent experiments have confirmed this result, ATLAS and CMS, the same experiments that originally observed the strange excess to begin with.
This shouldn’t be too disheartening, creating hypothesis and then attempting to prove them right is no more valuable to science than proving them wrong. It is quite interesting that despite The Large Hadron Collider (LHC) operating now at almost 95% power, nearing the fourteen teraelectronvolt maximum and still no unexpected results have arisen. This could make some people believe that perhaps the standard particle model is perfect and there are truly no more elementary particles to be discovered. But it is important to remember that it is impossible to know that no other particle exists, all we can do is keep looking for proof. Currently the LHC has collected merely a sixth of the data that scientists are intending to gather before 2018 and so there is plenty of time for a new discovery to be made.
