High-dimensional and permutation invariant anomaly detection [PDF]
SciPost Physics, 2023 Methods for anomaly detection of new physics processes are often limited to low-dimensional spaces due to the difficulty of learning high-dimensional probability densities. Particularly at the constituent level, incorporating desirable properties such as

Gauge-invariant and anyonic-symmetric autoregressive neural network for quantum lattice models [PDF]
Physical Review Research, 2023 Symmetries such as gauge invariance and anyonic symmetry play a crucial role in quantum many-body physics. We develop a general approach to constructing gauge-invariant or anyonic-symmetric autoregressive neural networks, including a wide range of ...

Lattice gauge tensor networks [PDF]
New Journal of Physics, 2014 We present a unified framework to describe lattice gauge theories by means of tensor networks: this framework is efficient as it exploits the high local symmetry content native to these systems by describing only the gauge invariant subspace. Compared to

Top Quark Pairs at High Invariant Mass - A Model-Independent Discriminator of New Physics at the LHC [PDF]
, 2006 We study top quark pair production to probe new physics at the LHC. We propose reconstruction methods for $t\bar{t}$ semileptonic events and use them to reconstruct the $t\bar{t}$ invariant mass. The angular distribution of top quarks in their c.m. frame

Bounce Cosmology in a Locally Scale Invariant Physics with a U(1) Symmetry
UniverseAn asymmetric non-singular bouncing cosmological model is proposed in the framework of a locally scale-invariant scalar-tensor version of the standard model of particle physics and gravitation. The scalar field ϕ is complex.
