Stability of the de-Sitter universe: One-loop nonlocal gravity
Haiyuan Feng, Yi Liao, Rong-Jia Yang
With the method of the background field expansion, we investigate the one-loop quantization of the Euclidean nonlocal model in the de-Sitter universe. We obtain the ghost-fr…
One-loop Matching of Scotogenic Model onto Standard Model Effective Field Theory up to Dimension 7
Yi Liao, Xiao-Dong Ma
The scotogenic neutrino seesaw model is a minimal extension of the standard model with three -odd right-handed singlet fermions and one -odd Higgs d…
Effective field theory approach to lepton number violating decays
Yi Liao, Xiao-Dong Ma, Hao-Lin Wang
We continue our endeavor to investigate lepton number violating (LNV) processes at low energy in the framework of effective field theory (EFT). In this work we study the LNV tau de…
An explicit construction of the dimension-9 operator basis in the standard model effective field theory
Yi Liao, Xiao-Dong Ma
We investigate systematically dimension-9 operators in the standard model effective field theory which contains only standard model fields and respects its gauge symmetry. With the…
Extending low energy effective field theory with a complete set of dimension-7 operators
Yi Liao, Xiao-Dong Ma, Quan-Yu Wang
We present a complete and independent set of dimension-7 operators in the low energy effective field theory (LEFT) where the dynamical degrees of freedom are the standard model fiv…
Imprint of a new light particle at KOTO?
Yi Liao, Hao-Lin Wang, Chang-Yuan Yao +1
Recently, the KOTO experiment reported their new preliminary result of searching for the decay . Three candidate events were observed in the signal region, which e…
