Direct Coupling of the Higgs Boson to the Top Quark Observed
If my layperson's understanding is correct (probably vastly generalized), this should be considered exciting news.  A few years ago the existence of the Higgs Boson was confirmed with some degree of confidence.  These Higgs Bosons are produced when particles interact with the Higgs Field giving them mass.The next question from that was - is that really the Higgs Boson, does it behave the way we expect it to (according to standard model)?  I believe this is a test to verify that it does and they measured the coupling constant and it matched up.  Neat. This could help with a much deeper understanding of why particles have mass.
