Flavor and CP Symmetries in the Standard Model Effective Field Theory
Hao Sun, Jiang-Hao Yu
The CP properties of effective operators are closely related to the spacetime and internal symmetries, such as the flavor symmetry, in the standard model effective field theory (SM…

Chiral Effective Field Theories for Strong and Weak Dynamics
Hao Sun, Yi-Ning Wang, Jiang-Hao Yu
The chiral effective field theory (ChEFT) is an extension of the chiral perturbation theory that includes the nuclear forces and weak currents at the hadronic and nuclear scales. W…

Systematic Spurion Matching between Low Energy EFT and Chiral Lagrangian
Chuan-Qiang Song, Hao Sun, Jiang-Hao Yu
The hadronic chiral Lagrangian can be matched from the low energy effective field theory (LEFT) operators at the quark level. Traditionally, as the mass dimension of the LEFT opera…
