Muon at multi-TeV muon collider
Wen Yin, Masahiro Yamaguchi
The long-standing discrepancy of muon is a hint of new physics beyond the standard model of particle physics. In this letter we show that heavy new physics contribution can b…
A Novel Approach to Fine-Tuned Supersymmetric Standard Models -- Case of Non-Universal Higgs Masses model
Masahiro Yamaguchi, Wen Yin
Discarding the prejudice about fine tuning, we propose a novel and efficient approach to identify relevant regions of fundamental parameter space in supersymmetric models with some…
Higgs Mixing in the NMSSM and Light Higgsinos
Kwang Sik Jeong, Yutaro Shoji, Masahiro Yamaguchi
We explore the effects of Higgs mixing in the general next-to-minimal supersymmetric Standard Model (NMSSM). Extended to include a gauge singlet, the Higgs sector can naturally exp…
Core-excitation three-cluster model description of ^8He and ^10He
H. Kamada, M. Yamaguchi, E. Uzu
We introduce a new model applying to the core-nucleus and two-neutron system. The Faddeev equations of 6He-n-n and 8He-n-n systems for 8He and 10He are solved, respectively. The po…
Higgs mixing and diphoton rate enhancement in NMSSM models
Kiwoon Choi, Sang Hui Im, Kwang Sik Jeong +1
We study the implications of the LHC Higgs signals on the Higgs mixing in the next-to-minimal supersymmetric standard model (NMSSM). The Higgs couplings can depart from their value…
Singlet-doublet Higgs mixing and its implications on the Higgs mass in the PQ-NMSSM
Kwang Sik Jeong, Yutaro Shoji, Masahiro Yamaguchi
We examine the implications of singlet-doublet Higgs mixing on the properties of a Standard Model (SM)-like Higgs boson within the Peccei-Quinn invariant extension of the NMSSM (PQ…
