5. Re (ϵ K ′ /ϵ K ) and K → π ν ν ¯ $$ K\to \pi \nu \overline{\nu} $$ in a two-Higgs doublet model / Chen, Chuan-Hung ; Nomura, Takaaki
The Kaon direct CP violation Re (ϵ K ′ /ϵ K ) below the experimental data of a 2 σ in the standard model, which is calculated using the RBC-UKQCD lattice and a large N c dual QCD, indicates the necessity of a new physics effect. [...]
