UV stability of 1-loop radiative corrections in higher-derivative scalar field theory
Yugo Abe, Takeo Inami, Keisuke Izumi
We consider the theory of a higher-derivative (HD) real scalar field coupled to a complex scalar , the coupling of the and being given by two types, $λ_{σϕ}σ^\dagger…
High-energy properties of the graviton scattering in quadratic gravity
Yugo Abe, Takeo Inami, Keisuke Izumi
We obtain the matter-graviton scattering amplitude in the gravitational theory of quadratic curvature, which has term in the action. Unitarity bound is not satisfied bec…
Heavy particle non-decoupling in flavor-changing gravitational interactions
Takeo Inami, Takahiro Kubota
The flavor-changing gravitational process d --> s + graviton, is evaluated at the one-loop level in the standard electroweak theory with on-shell renormalization. The results we pr…
Isotropic parallel antiferromagnetism in the magnetic-field-induced charge-ordered state of SmRuP caused by - hybridization
T. Matsumura, S. Michimura, T. Inami +12
Nature of the field-induced charge ordered phase (phase II) of SmRuP has been investigated by resonant x-ray diffraction (RXD) and polarized neutron diffraction (PND), f…
Perturbative -matrix unitarity () in gravity
Yugo Abe, Takeo Inami, Keisuke Izumi
We show that in the quadratic curvature theory of gravity, or simply gravity, the tree-level unitariy bound (tree unitarity) is violated in the UV region but an analog…
Physical constraints derived from FCNC in the 3-3-1-1 model
N. T. Duy, Takeo Inami, D. T. Huong
We investigate several phenomena related to FCNCs in the model. The sources of FCNCs at the tree-level from both the gauge and Higgs sectors are clarified. Experim…
