Festina-Lente Bound on Higgs Vacuum Structure and Inflation
Sung Mook Lee, Dhong Yeon Cheong, Sang Chul Hyun +2
The recently suggested Festina-Lente (FL) bound provides a lower bound on the masses of charged particles in terms of the positive vacuum energy. Since the charged par…
Implications of the dark axion portal for the muon g-2, B-factories, fixed target neutrino experiments and beam dumps
Patrick deNiverville, Hye-Sung Lee, Min-Seok Seo
The dark axion portal is a recently introduced portal between the standard model and the dark sector. It connects both the dark photon and the axion (or axion-like particle) to the…
SIMP dark matter and its cosmic abundances
Soo-Min Choi, Hyun Min Lee, Min-Seok Seo
We give a review on the thermal average of the annihilation cross-sections for and general higher-order processes. Thermal average of higher order annihilations hi…
Cosmic abundances of SIMP dark matter
Soo-Min Choi, Hyun Min Lee, Min-Seok Seo
Thermal production of light dark matter with sub-GeV scale mass can be attributed to self-annihilation processes. We consider the thermal average for annihilation…
Investigating the jet activity accompanying the production at the LHC of a massive scalar particle decaying into photons
Benjamin Fuks, Dong Woo Kang, Seong Chan Park +1
We study the jet activity that accompanies the production by gluon fusion of a new physics scalar particle decaying into photons at the LHC. In the considered scenarios, both the p…
Gauge see-saw: A mechanism for a light gauge boson
Hye-Sung Lee, Min-Seok Seo
There has been rapidly growing interest in the past decade in a new gauge boson which is considerably lighter than the standard model Z boson. A well-known example of this kind is…
Models for SIMP dark matter and dark photon
Hyun Min Lee, Min-Seok Seo
We give a review on the SIMP paradigm and discuss a consistent model for SIMP dark mesons in the context of a dark QCD with flavor symmetry. The -portal interaction is introduc…
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…
Communication with SIMP dark mesons via Z'-portal
Hyun Min Lee, Min-Seok Seo
We consider a consistent extension of the SIMP models with dark mesons by including a dark U(1)_D gauge symmetry. Dark matter density is determined by a thermal freeze-out of the $…
Peccei-Quinn invariant singlet extended SUSY with anomalous U(1) gauge symmetry
Sang Hui Im, Min-Seok Seo
Recent discovery of the SM-like Higgs boson with GeV motivates an extension of the minimal supersymmetric standard model (MSSM), which involves a singlet Higgs supe…
Higgs phenomenology in the Peccei-Quinn invariant NMSSM
Kiwoon Choi, Sang Hui Im, Kwang Sik Jeong +1
We study the Higgs phenomenology in the Peccei-Quinn invariant NMSSM (PQ-NMSSM) where the low energy mass parameters of the singlet superfield are induced by a spontaneous breakdow…
Neutrino Assisted Gauge Mediation
Hyung Do Kim, Doh Young Mo, Min-Seok Seo
Recent observation shows that the Higgs mass is at around 125 GeV while the prediction of the minimal supersymmetric standard model is below 120 GeV for stop mass lighter than 2 Te…
Axino mass
Jihn E. Kim, Min-Seok Seo
I will talk on my recent works. Axino, related to the SUSY transformation of axion, can mix with Goldstino in principle. In this short talk, I would like to explain what is the axi…
Mixing of axino and goldstino, and axino mass
Jihn E. Kim, Min-Seok Seo
Axino, related to the SUSY transformation of axion, can mix with goldstino in principle. This case is realized when some superfields carrying nonvanishing Peccei-Quinn charges deve…
A simple expression of the Jarlskog determinant
Jihn E. Kim, Min-Seok Seo
Making the whole determinant of the CKM matrix V real, the imaginary part of any one term of the determinant of V (e. g. |Im V_{31}V_{22}V_{13}|) is the Jarlskog determinant J. We…
Singlet superfield extension of the minimal supersymmetric standard model with Peccei-Quinn symmetry and a light pseudoscalar Higgs boson at the LHC
Jihn E. Kim, Hans Peter Nilles, Min-Seok Seo
Motivated by the mu-problem and the axion solution to the strong CP-problem, we extend the MSSM with one more chiral singlet field . The underlying PQ-symmetry allows only one…
Gauge mediation to effective SUSY through U(1)s with a dynamical SUSY breaking, and string compactification
Kwang Sik Jeong, Jihn E. Kim, Min-Seok Seo
We investigate the possibility of U(1)' mediation, leading to an effective SUSY where the first two family sfermions are above 100 TeV but the third family sfermions and the Higgs…
Parametrization of PMNS matrix based on dodeca-symmetry
Jihn E. Kim, Min-Seok Seo
The dodeca symmetry is designed to obtain the Cabibbo angle approximately and the (11) element of $\Vp$ as , leading to $θ_1^{\rm PMNS…
An exact CKM matrix related to the approximate Wolfenstein form
Jihn E. Kim, Min-Seok Seo
Noting the hierarchy between three mixing angles, , we present an exact form of the quark mixing matrix, replacing Wolfenstein's approximate form. In addit…

Quark and lepton mixing angles with a dodeca-symmetry
Jihn E. Kim, Min-Seok Seo
The discrete symmetry D_12 at the electroweak scale is used to fix the quark and lepton mixing angles. At the leading order, the Cabbibo angle theta_C is 15^o, and the PMNS matrix…
