Measuring Lorentz Violation in Weak Gravity Fields
Zonghao Li
Many new linearized coefficients for Lorentz violation are discovered in our recent work on the construction of a generic Lorentz-violating effective field theory in curved spaceti…
Weakly Supervised Semantic Segmentation for Large-Scale Point Cloud
Yachao Zhang, Zonghao Li, Yuan Xie +3
Existing methods for large-scale point cloud semantic segmentation require expensive, tedious and error-prone manual point-wise annotations. Intuitively, weakly supervised training…
Mean-square invariant manifolds for ill-posed stochastic evolution equations driven by nonlinear noise
Zonghao Li, Caibin Zeng, Jianhua Huang
This paper discerns the invariant manifold of a class of ill-posed stochastic evolution equations driven by a nonlinear multiplicative noise. To be more precise, we establish the e…
Lorentz violation in the matter-gravity sector
Zonghao Li
We construct the general Lorentz-violating effective field theory in curved spacetime and the corresponding nonrelativistic Hamiltonian in the Earth's gravitational field. Applying…
Searches for beyond-Riemann gravity
Alan Kostelecky, Zonghao Li
Many effective field theories describing gravity cannot arise from an underlying theory based on Riemann geometry or its extensions to include torsion and nonmetricity but may inst…
Nonminimal Lorentz-Violating Extensions of Gauge Field Theories
Zonghao Li
A general method is presented to build all gauge-invariant terms in gauge field theories, including quantum electrodynamics and quantum chromodynamics. It is applied to two experim…
Backgrounds in gravitational effective field theory
Alan Kostelecky, Zonghao Li
Effective field theories describing gravity coupled to matter are investigated, allowing for operators of arbitrary mass dimension. Terms violating local Lorentz and diffeomorphism…
Searching for Lorentz violation in high-energy colliders
Zonghao Li
Lorentz violation has been a popular field in recent years in the search for new physics beyond the Standard Model. We present a general method to build all Lorentz-violating terms…
Gauge field theories with Lorentz-violating operators of arbitrary dimension
Alan Kostelecky, Zonghao Li
The classification of Lorentz- and CPT-violating operators in nonabelian gauge field theories is performed. We construct all gauge-invariant terms describing propagation and intera…
