It’s hard to understate the significance of the science that has been done because of the Large Hadron Collider. Whilst it’s famously known for discovering the Higgs-Boson, the particle which gives all other particles mass, it has a long list of achievements outside of that singular event. What makes these discoveries even more interesting is that the LHC has been operating at something of a disadvantage since it was first turned on over 6 years ago, operating at around half the potential energy it was capable of. Shortly after the discovery of the Higgs Boson the scientists and engineers at CERN have been working to bring it up to full capacity and with it the potential for some even more radical discoveries.

The doubling of the collision energy increases the potential for the LHC to generate even more exotic particles than it has previously, ones which can give us insights into some of the most perplexing mysteries in particle physics to date. One such source of intrigue is how our universe, which is composed of nearly entirely matter, came to be that way. Another seeks to explain why the universe seems to be riddled with matter that’s not directly observable but is seen through its gravitational effects throughout the universe. These, and many other questions, have potential to find answers in the newly upgraded LHC which is slated to come online this year.

In the beginning, the beginning of everything according to scientific theory, there existed both equal quantities of matter and antimatter. Upon annihilation these two entities should have completely destroyed each other, leaving behind a wake of energy with no matter to speak of. However casual observation will show that our world, and the rest of the universe, is dominated by matter. This strange preference for matter (dubbed the CP Violation) has perplexed scientists for decades however the newly upgraded LHC has the potential to shed some light on where the Universe’s strange preference comes from. The LHCb detector focuses on the decay of the Beauty Quark, a fundamental particle that decays in all manner of strange ways when created in a collider. Studying these decays could grant us insight into where the CP violation comes from and why we live in a matter dominated universe.

However what’s far more interesting (for me at least) is that the LHC could have the potential to generate dark matter, the highly pervasive as-of-yet unobserved substance that binds galaxies together via its gravitational influence. There’s numerous theories that posit dark matter being made up of WIMPs (Weakly Interacting Massive Particles) which could potentially be generated in the LHC. It’s highly unlikely that we’ll be able to detect them directly, their very nature means that they’re far more likely to simply pass through the detectors, however should we generate them their signature will be left on the reactions. Essentially we’ll be looking for a reaction that’s missing energy and then seeing if that can be explained by a WIMP being generated. Should we find that we’ll have a solid basis to further investigate this elusive form of matter, furthering our understanding of just what makes up our universe.

It’ll likely be another few years before we hear any further news from the LHC as it’s going to take time to generate the data and even longer to sift through it to find the reactions we’re looking for. However I’m very confident that the results will forever change the scientific landscape as either confirmation of current theories or evidence against them will provide dozens of more avenues for further research. That, to me, is the beauty of science, the never ending search for answers that inevitably lead to more questions, starting the process of discovery all over again.
