D0 dimuon charge asymmetry from B_s system with Z' couplings and the recent LHCb result
Hyung Do Kim, Sung-Gi Kim, Seodong Shin
The D0 collaboration has announced the observation of the like-sign dimuon charge asymmetry since 2010, which has more than 3σdeviation from the Standard Model prediction. One of t…
Z' near the Z-pole
Radovan Dermisek, Sung-Gi Kim, Aditi Raval
We present a fit to precision electroweak data in the standard model extended by an additional vector boson, Z', with suppressed couplings to the electron compared to the Z boson,…
New Vector Boson Near the Z-pole and the Puzzle in Precision Electroweak Data
Radovan Dermisek, Sung-Gi Kim, Aditi Raval
We show that a Z' with suppressed couplings to the electron compared to the Z-boson, with couplings to the b-quark, and with a mass close to the mass of the Z-boson, provides an ex…
Spontaneous CP violation in E6 SUSY GUT with SU(2) flavor and anomalous U(1) symmetries
M. Ishiduki, S. -G. Kim, N. Maekawa +1
We construct a model of spontaneous CP violation in E6 supersymmetric grand unified theory. In the model, we employ an SU(2)F flavor symmetry and an anomalous U(1)A symmetry. The S…
LHC signature of supersymmetric models with non-universal sfermion masses
Sung-Gi Kim, Nobuhiro Maekawa, Keiko I. Nagao +2
We study the LHC signature of the minimal supersymmetric standard model with non-universal sfermion masses. In the model, soft masses of gauginos and the 3rd generation of 10 of SU…
D-term assisted Anomaly Mediation in E6 motivated models
Masaki Asano, Tatsuru Kikuchi, Sung-Gi Kim
We investigate effects of D-term contributions to the anomaly mediated supersymmetry breaking scenario. If we introduce an E6 GUT motivated D-term, it is possible that slepton mass…
CP asymmetries of B to phi K_S and B to eta' K_S in SUSY GUT Model with Non-universal Sfermion Masses
S. -G. Kim, N. Maekawa, A. Matsuzaki +2
We analyze CP asymmetries of B \to ϕK_S and B \to η' K_S in a supersymmetric grand unified theory in which only the third generation sfermions contained in 10(Q, U^c, E^c) of SU(5)…
