WebOne could solve the hierarchy problem by introducing new degrees of freedom that enforce such a cancellation as a symmetry requirement (rather than accidentally) which would suppress the couplings of the relevant operator. For example: Supersymmetry (SUSY). By the way, QCD doesn't have the hierarchy problem (apart from the strong CP-problem...). A hierarchy problem occurs when the fundamental value of some physical parameter, such as a coupling constant or a mass, in some Lagrangian is vastly different from its effective value, which is the value that gets measured in an experiment. This happens because the effective value is related to … Ver mais In theoretical physics, the hierarchy problem is the problem concerning the large discrepancy between aspects of the weak force and gravity. There is no scientific consensus on why, for example, the Ver mais The Higgs mass In particle physics, the most important hierarchy problem is the question that asks why the weak force is 10 times as strong as gravity.
