They predicted and found the Higgs, but things like more particles that helped explain why the mass of the Higgs isn't what it should be, hoped to find things like super symmetry, extra dimensions, strings, new combinations of old particles, but it literally found nothing. (Im not an expert but am paraphrasing talks Ive hear from Sean Carrol). All it found was the Higgs and nothing else, and I think that is more than puzzling for physicists. The good thing is particle and quantum physicists like puzzles.
