Hey guys, Being interested in science (and living in Switzerland), I've been reading a lot about the Higgs boson in mainstream news. Unfortunately, the best thing I can get out of that kind of report is the overused analogy of some celebrity moving in a crowd. I have practically no understanding of QFT, but I'm doing a masters in theoretical chemistry which means I do have a good grasp on QM. I was wondering if you guys could explain to me what is the big deal with the Higgs boson . I get it that it gives mass to particles, but that doesn't really mean much to me. Why isn't there a particle that gives charge to particles? If it gives mass to particles, isn't it intimately connected with the gravitational force (even though it is not the graviton)? How do people at CERN know that what they have detected is a boson and how they know its mass?
