1. Analysis of Dalitz decays with intrinsic parity-violating interactions in resonance chiral perturbation theory / Kimura, Daiji ; Morozumi, Takuya ; Umeeda, Hiroyuki
Observables of light hadron decays are analyzed in a chiral Lagrangian model that includes resonance fields of vector mesons. [...]

2. Direct CP violation in Cabibbo-favored charmed meson decays and ϵ ′ / ϵ in SU(2) L × SU(2) R × U(1) B − L model / Haba, Naoyuki ; Umeeda, Hiroyuki ; Yamada, Toshifumi
Since the standard model contribution is virtually absent, any observation of direct CP violation in the Cabibbo-favored charmed meson decays would be evidence of new physics. [...]

4. Effective theory analysis for vector-like quark model / Morozumi, Takuya ; Shimizu, Yusuke ; Takahashi, Shunya ; Umeeda, Hiroyuki
We study a model with a down-type SU(2) singlet vector-like quark (VLQ) as a minimal extension of the standard model (SM). [...]

5. Semialigned two Higgs doublet model / Haba, Naoyuki ; Umeeda, Hiroyuki ; Yamada, Toshifumi
In the left-right symmetric model based on SU(2)L×SU(2)R×U(1)BL gauge symmetry, there appear heavy neutral scalar particles mediating quark flavor changing neutral currents (FCNCs) at tree level. [...]
