If the Higgs field (particle) is responsible for the property of "mass" in the Universe, can we assume that the Higgs particle is some how intertwined with the Graviton?? (both are supposedly classified as bosons. Although the Higgs field doesnt interact with other fields? Not like the TOP quark, which is a heavier particle than the Higgs Boson but can interact and therefore a little easier to produce and detect)
(1) The Higgs field is responsible for mass not the Higgs boson.
(2) The Higgs particle is only "associated" with bosons having mass such as the W and Z bosons through spontaneous symmetry breaking of the electroweak force. Gravitons are massless.
(3) The Higgs field is only accountable for about one percent of the observable mass in the Universe. While the Higgs field accounts for all the quark mass, it only accounts for about one percent of the mass of protons and neutrons each of which are composed of three quarks. The reason for this discrepancy is that 99% of the proton and neutron mass is taken up by binding energy that holds the quarks together which is not attributed to the Higgs field.
(4) Given the Top quark was the sixth and last quark to be discovered it was certainly not easier to produce and detect.
The larger mass required more powerful particle accelerators to produce the Top quark. Then there was the added complication that the Top quark immediately decayed into a Bottom quark which in turn decayed into a Charm quark which in turn decayed into a Strange quark. The difficult was digging out the signal attributed to the Top quark and not to the decay products.
