The answer is actually quite a lot! Not because the Higgs Boson particle itself will be used to transform our lives but because the investment in technology used to detect this elusive particle has resulted in significant advances that ARE being used in extremely innovative but practical R&D areas. The huge investment in detector technologies can be directly translated into advanced analysis techniques for medical applications, including low light level imaging, bioluminescence detection and next generation disease diagnostics and therapeutics.
