Is an axizilla possible for di-photon resonance?
Jihn E. Kim
Heavy axion-like particles, called axizillas, are simple extensions of the standard model(SM). An axizilla is required not to couple to the quarks, leptons, and Brout-Englert-Higgs…
Towards unification of GUT families
Jihn E. Kim
I discuss the mere 5 % of atoms in the cosmic energy pie. It is basically the chiral matter problem. Then, I review the chiral matter problem from a grand unification (GUT) point o…
An ultralight pseudoscalar boson
Jihn E. Kim, David J. E. Marsh
Using a fundamental discrete symmetry, , we construct a two-axion model with the QCD axion solving the strong- problem, and an ultralight axion (ULA) with $m_{\rm…
The CKM matrix from anti-SU(7) unification of GUT families
Jihn E. Kim, Doh Young Mo, Min-Seok Seo
We estimate the CKM matrix elements in the recently proposed minimal model, anti-SU(7) GUT for the family unification, +\,(singlets). It is sho…
Unifying CP violations of quark and lepton sectors
Jihn E. Kim, Soonkeon Nam
A preliminary determination of the Dirac phase in the PMNS matrix is $\dell\approx -\fracπ{2}$. A rather accurately determined Jarlskog invariant in the CKM matrix is close to…
Towards unity of families: anti-SU(7) from Z(12-I) orbifold compactification
Jihn E. Kim
The problem of families, "Why are there three families of fermions?", is a long awaited question to be answered within a reasonable framework. We propose anti-SU() groups for th…
