Yukawa Alignment Revisited in the Higgs Basis
Jae Sik Lee, Jubin Park
We implement a comprehensive and detailed study of the alignment of Yukawa couplings in the so-called Higgs basis taking the framework of general two Higgs doublet models (2HDMs).…
Decays of Higgs Bosons in the Standard Model and Beyond
Seong Youl Choi, Jae Sik Lee, Jubin Park
We make an updated review and a systematic and comprehensive analysis of the decays of Higgs bosons in the Standard Model (SM) and its three well-defined prototype extensions such…
Alignment of Yukawa couplings in two Higgs doublet models
Seong Youl Choi, Jae Sik Lee, Jubin Park
We study the alignment of Yukawa couplings in the framework of general two Higgs doublet models (2HDMs) considering a scenario in which the lightest neutral Higgs boson is purely C…
Measuring the trilinear Higgs boson self--coupling at the 100 TeV hadron collider via multivariate analysis
Jubin Park, Jung Chang, Kingman Cheung +1
We perform a multivariate analysis of Higgs-pair production via the decay channel at the future 100 TeV collider to determine the trilinear Higgs self--cou…
Probing Trilinear Higgs Self-coupling at the HL-LHC via Multivariate Analysis
Jung Chang, Kingman Cheung, Jae Sik Lee +1
We perform a multivariate analysis of Higgs-pair production in channel at the HL-LHC to probe the trilinear Higgs self--coupling , which takes the value…
Proceedings of the first MadAnalysis 5 workshop on LHC recasting in Korea
Benjamin Fuks, Samuel Bein, Guillaume Chalons +22
We present the activities performed during the first MadAnalysis 5 workshop on LHC recasting that has been organized at High 1 (Gangwon privince, Korea) on August 20-27, 2017. This…
Higgs-boson-pair production from gluon fusion at the HL-LHC and HL-100 TeV hadron collider
Jung Chang, Kingman Cheung, Jae Sik Lee +2
We perform the most up-to-date comprehensive signal-background analysis for Higgs-pair production in channel at the HL-LHC and HL-100 TeV hadron collider, with…
Measuring properties of a Heavy Higgs boson in the decay
Jung Chang, Kingman Cheung, Jae Sik Lee +2
Suppose a heavy neutral Higgs or scalar boson is discovered at the LHC, it is important to investigate its couplings to the standard model particles as much as possible. Here i…
Measuring properties of a Heavy Higgs boson in the decay
Jung Chang, Kingman Cheung, Jae Sik Lee +2
In many extensions of the standard model, there exist a few extra Higgs bosons. Suppose a heavy neutral Higgs boson H is discovered at the LHC, one could then investigate CP and CP…
Double Higgcision: 125 GeV Higgs boson and a potential diphoton Resonance
Kingman Cheung, P. Ko, Jae Sik Lee +2
Searches for diphoton resonance have been shown to be very useful in discovering new heavy spin-0 or spin-2 particles. Supposing that a new heavy particle shows up in the diphoton…
Higgs precision study of the 750 GeV diphoton resonance and the 125 GeV standard model Higgs boson with Higgs-singlet mixing
Kingman Cheung, P. Ko, Jae Sik Lee +2
We interpret the potential observation of the 750 GeV di-photon resonance at the LHC in models, in which an isospin-singlet scalar boson mixes with the Standard Model (SM)…
Low scale quantum gravity in gauge-Higgs unified models
Jubin Park
We consider the scale at which gravity becomes strong in linearized General Relativity coupled to the gauge-Higgs unified(GHU) model. We also discuss the unitarity of S-matrix in t…
Unitarity Constraints in the standard model with a singlet scalar field
Sin Kyu Kang, Jubin Park
Motivated by the discovery of a new scalar field and amelioration of the electroweak vacuum stability ascribed to a singlet scalar field embedded in the standard model (SM), we exa…
Two Higgs Doublets Model in Gauge-Higgs Unification framework
We-Fu Chang, Sin Kyu Kang, Jubin Park
We discuss the realization of two Higgs doublets model in the framework of 6 dimensional Gauge-Higgs Unification model with a simple Lie group G_M. Two Higgs SU(2)_L doublets can e…
Discrimination of the light CP-odd scalars between in the NMSSM and in the SLHM
C. S. Kim, Kang Young Lee, Jubin Park
The presence of the light CP-odd scalar boson predicted in the next-to-minimal supersymmetric model (NMSSM) and the simplest little Higgs model (SLHM) dramatically changes the phen…
Weak Mixing Angle and Higgs Mass in Gauge-Higgs Unification Models with Brane Kinetic Terms
Jubin Park, Sin Kyu Kang
We show that the idea of Gauge-Higgs unification(GHU) can be rescued from the constraint of weak mixing angle by introducing localized brane kinetic terms in higher dimensional GHU…
Little Higgs model with new Z-parity and Dark matter
C. S. Kim, Jubin Park
It has been known that Little Higgs models with T-parity, which can give a dark matter candidate, suffer from the anomalies of given models through the Wess-Zumino-Witten term, whi…
Test of the Littlest Higgs model through the correlation among W boson, top quark and Higgs masses
Sin Kyu Kang, C. S. Kim, Jubin Park
Motivated by the recent precision measurements of the W boson mass and top quark mass, we test the Littlest Higgs model by confronting the prediction of M_W with the current and pr…
