A HEFT Perspective on the Type-II Seesaw Model and the Complete Basis of Lepton-Number-Violating Operators
Zizhou Ge, Huayang Song, Xia Wan
We perform the complete tree-level matching of the type-II seesaw model onto the Higgs effective field theory (HEFT) through in the chiral expansion. Employing a…
Establishing the Primary HEFT as a Precision Benchmark for UV-HEFT Matching
Zizhou Ge, Huayang Song, Xia Wan
We match the real Higgs triplet model (RHTM) onto HEFT under different parameter choices and power-counting schemes, thereby obtaining several representative HEFT formulations and…
Matching the real Higgs triplet extension of Standard Model to HEFT
Huayang Song, Xia Wan
We make a first matching of the real Higgs triplet extension (RHTE) of the standard model to the Higgs effective field theory (HEFT), which is also known as electroweak chiral Lagr…
A Non-linear Representation of General Scalar Extensions of the Standard Model for HEFT Matching
Huayang Song, Xia Wan
We introduce a non-linear representation of ultraviolet~(UV) complete model, representation, under which matching HEFT to general scalar extensions of the standard model is str…
