Since discovering the Higgs boson in 2012, the ATLAS Collaboration at CERN has been working to understand its properties. One question in particular stands out: why does the Higgs boson have the mass that it does? Experiments have measured its mass to be around 125 GeV--yet the Standard Model implies it has much larger mass and requires a very large correction to the mathematics in order to align theory with observation, leading to the "naturalness problem."
