QCD knows new quarks
Chuan-Xin Cui, Hiroyuki Ishida, Mamiya Kawaguchi +3
We find that a big gap between indicators for the breaking strengths of the global chiral SU(2) and U(1) axial symmetries in QCD of the Standard Model (SM) can be interpreted as a…
Probing an intrinsically flavorful ALP via tau-lepton flavor physics
Chuan-Xin Cui, Hiroyuki Ishida, Shinya Matsuzaki +1
Any axionlike particle (ALP) intrinsically possesses flavorful couplings to the standard model (SM) fermions arising as a consequence of the right-handed flavor rotation within the…
Peccei-Quinn Symmetry Breaking via Asymptotically Safe Dynamical Scalegenesis: A Walking Axicolor and Axion
Hiroyuki Ishida, Shinya Matsuzaki, Xiao-Chang Peng
Pecci-Quinn (PQ) symmetry breaking by perturbative dynamics would suffer from a hierarchy problem, just like the electroweak symmetry breaking in the standard model. The dynamics o…
Neutrinoless double beta decays tell nature of right-handed neutrinos
Takehiko Asaka, Hiroyuki Ishida, Kazuki Tanaka
We consider the minimal seesaw model, the Standard Model extended by two right-handed neutrinos, for explaining the neutrino masses and mixing angles measured in oscillation experi…
Hiding neutrinoless double beta decay in the minimal seesaw mechanism
Takehiko Asaka, Hiroyuki Ishida, Kazuki Tanaka
We present a possibility that the neutrinoless double beta decay can be hidden in the minimal seesaw mechanism where the standard model is extended by two right-handed neutrinos wh…
