The smallness of the Higgs boson mass, the cosmological constant, and the explicit breaking of the Peccei–Quinn symmetry are usually regarded as independent theoretical challenges. We show that these puzzles become interrelated when Einstein–Cartan gravity is incorporated into the Standard Model in a Weyl-invariant way. The resulting framework introduces only a single additional scalar degree...
It is argued that the SMEFT cannot be used to derive constraints on weakly-coupled heavy new particles from LHC data. Depending on the UV-complete model, the bounds derived using the SMEFT implementation can be considerably stronger or much weaker than the true constraints on the model. This is true even for an "SMEFT-friendly" scenario without 2 --> 1 resonance production. Combinatorial...
