Baryon number non-conservation as Peccei-Quinn mechanism
Takahiro Ohata, Kengo Takeuchi, Koji Tsumura
Baryon number is an accidental symmetry in the standard model, while Peccei-Quinn symmetry is hypothetical symmetry which is introduced to solve the strong CP problem. We study the…
Pseudo-Nambu-Goldstone Dark Matter Model Inspired by Grand Unification
Yoshihiko Abe, Takashi Toma, Koji Tsumura +1
A pseudo-Nambu-Goldstone boson (pNGB) is an attractive candidate for dark matter (DM) due to the simple evasion of the current severe limits of DM direct detection experiments. One…
Scalar and fermion on-shell amplitudes in generalized Higgs effective field theory
Ryo Nagai, Masaharu Tanabashi, Koji Tsumura +1
Beyond standard model (BSM) particles should be included in effective field theory in order to compute the scattering amplitudes involving these extra particles. We formulate an ex…
