96 GeV Scalar Boson in the 2HDM with U(1)_H Gauge Symmetry
Seungwon Baek, P. Ko, Yuji Omura +1
In this paper, we study two Higgs doublet models with gauged U(1)_H symmetry, motivated by the excesses around 96 GeV reported by the CMS collaboration in the searches for light re…
Constraints on the dark Z model from the Higgs boson phenomenology
Dong-Won Jung, Kang Young Lee, Chaehyun Yu
We study constraints on the hidden sector model mediated by an additional SU(2) Higgs doublet from the phenomenology of Higgs bosons. The hidden sector is assumed to contain a hidd…
Positronium Decays with Dark and Fermionic Dark Matter
Dong-Won Jung, Chaehyun Yu, Kang Young Lee
We investigate the invisible decay of positronium to probe the fermionic light dark matter mediated by the dark boson. Too tiny is the invisible decay rate of positronium throu…
Derivation of Jacobian Formula with Dirac Delta Function
Dohyun Kim, June-Haak Ee, Chaehyun Yu +1
We demonstrate how to make the coordinate transformation or change of variables from Cartesian coordinates to curvilinear coordinates by making use of a convolution of a function w…
Proof of Cramer's rule with Dirac Delta Function
June-Haak Ee, Jungil Lee, Chaehyun Yu
We present a new proof of Cramer's rule by interpreting a system of linear equations as a transformation of -dimensional Cartesian-coordinate vectors. To find the solution, we c…
Singlet Fermionic Dark Matter with Dark
Dong-Won Jung, Soo-hyeon Nam, Chaehyun Yu +2
We present a fermionic dark matter model mediated by the hidden gauge boson. We assume the QED-like hidden sector which consists of a Dirac fermion and U(1) gauge symmetry, and…
