Minimal Models for Axion and Neutrino

Y. H. Ahn, Eung Jin Chun

The PQ mechanism resolving the strong CP problem and the seesaw mechanism explaining the smallness of neutrino masses may be related in a way that the PQ symmetry breaking scale an…

Muon g2 in two-Higgs-doublet models

Eung Jin Chun

Updating various theoretical and experimental constraints on the four different types of two-Higgs-doublet models (2HDMs), we find that only the ``lepton-specific" (or ``type X") 2…

Electro-Weak Dark Matter: non-perturbative effect confronting indirect detections

Eung Jin Chun, Jong-Chul Park

We update indirect constraints on Electro-Weak Dark Matter (EWDM) considering the Sommerfeld-Ramsauer-Townsend (SRT) effect for its annihilations into a pair of standard model gaug…

LHC -rich Tests of Lepton-specific 2HDM for

Eung Jin Chun, Zhaofeng Kang, Michihisa Takeuchi +1

The lepton-sepcific (or type X) 2HDM (L2HDM) is an attractive new physics candidate explaining the muon anomaly requiring a light CP-odd boson and large . This sce…

Diluting the inflationary axion fluctuation by a stronger QCD in the early Universe

Kiwoon Choi, Eung Jin Chun, Sang Hui Im +1

We propose a new mechanism to suppress the axion isocurvature perturbation, while producing the right amount of axion dark matter, within the framework of supersymmetric axion mode…
