HIGHLIGHTS
- who: Nobuhito Maru from the Department of Mathematics and Physics, Osaka City University, Osaka, Japan have published the article: Improving fermion mass hierarchy in grand gauge-Higgs unification with localized gauge kinetic terms, in the Journal: Eur. Phys. J. C (2020) 80:933 of /2020/
- what: In this approach, the SM fermions are introduced on the boundaries (i.e. fixed point in an orbifold compactification). In the following section, the authors determine the remaining parity of P15. In the previous paper , the up-type quark masses could not be larger than W boson mass, although . . .
