Abstract We discuss heavy particles that can be used to pin down the faithful Standard Model (SM) gauge group and their patterns in the SM effective field theory (SMEFT). These heavy particles are not invariant under a specific ℤ 6 subgroup of SU(3

Abstract We present a model that solves the strong CP problem via an axion parametrically heavier than the standard one. Within this picture the Standard Model quarks are embedded into a larger non-abelian Grand Color group that at high scales splits

Abstract Recent works argue that the pattern of chiral symmetry breaking in QCD-like theories can be derived from supersymmetric (SUSY) QCD with perturbation of anomaly-mediated SUSY breaking (AMSB). Nevertheless, despite the fact that AMSB needs to

Abstract Composite Higgs and neutral-naturalness models are popular scenarios in which the Higgs boson is a pseudo Nambu-Goldstone boson (PNGB), and naturalness problem is addressed by composite top partners. Since the standard model effective field

If the Higgs boson is a pseudo Nambu–Goldstone boson (PNGB), the hZγ contact interaction induced by the O(p4) invariants of the non-linear sigma model is free from its nonlinearity effects. The process h→Zγ can be used to eliminate the universa

The top quark Yukawa coupling (yt) can be modified by two dimension-six operators OH and Oy with the corresponding Wilson coefficients cH and cy, whose individual contribution cannot be distinguished by measuring yt alone. However, such a degeneracy

We propose soft breaking mechanism for dark matter (DM) shift symmetry in a class of composite dark matter models, where both DM and the Higgs boson arise as pseudo Nambu-Goldstone bosons from novel strong dynamics. Our mechanism is utilized to suppr

Although the Higgs boson has been discovered, its self-couplings are poorly constrained. This leaves the nature of the Higgs boson undetermined. Motivated by different Higgs potential scenarios other than the Landau-Ginzburg type in the standard mode
