Complete UV Resonances of SMEFT Dim-9 Operators for Short-range Neutrinoless Double Beta Decay
Hao-Lin Li, Yu-Han Ni, Ming-Lei Xiao +2
We present a systematic classification of tree-level ultraviolet (UV) completions for dimension-nine SMEFT operators relevant to short-range neutrinoless double beta decay. Using t…
Confinement without symmetry breaking in chiral gauge theories
Haolin Li, Ãlvaro Pastor-Gutiérrez, Shahram Vatani
The infrared structure of gauge theories with chiral fermions remains largely unexplored. In this work we investigate the Bars-Yankielowicz class using the functional renormalisati…
Partial-Wave Unitarity Bounds on Higher-Dimensional Operators from 2-to- Scattering
Céline Degrande, Hao-Lin Li, Ling-Xiao Xu
We present a systematic method for deriving partial-wave unitarity bounds on Wilson coefficients of higher-dimensional operators in effective field theories involving more than fou…
Dynamical symmetry breaking in Georgi-Glashow chiral-gauge theories
Hao-Lin Li, Ãlvaro Pastor-Gutiérrez, Shahram Vatani +1
We investigate dynamical symmetry breaking in a class of chiral gauge theories containing the Georgi-Glashow model. These theories feature a gauge sector and two fermion species th…
