Model-Independent Searches for New Physics in Multi-Body Invariant Masses [PDF]

open access: yesUniverse, 2021
Model-independent searches for physics beyond the Standard Model typically focus on invariant masses of two objects (jets, leptons or photons). In this study, we explore opportunities for similar model-agnostic searches in multi-body invariant masses. In

SYMMETRIES AND INVARIANCES IN CLASSICAL PHYSICS [PDF]

open access: yes, 2007
This Chapter discusses the role of symmetry in classical physics. We begin, in Section 2, with the distinction between symmetries of objects and of laws, and that between symmetry principles and symmetry arguments, including a discussion of Curie’s principle.

Accurate protein-protein interactions modeling through physics-informed geometric invariant learning [PDF]

open access: yesCommunications Biology
AlphaFold has set a new standard for predicting protein structures from primary sequences; however, it faces challenges with protein complexes across species, engineered proteins, and antigen-antibody interactions, where co-evolutionary signals may be ...

Invariant Set Theory: Violating Measurement Independence without Fine Tuning, Conspiracy, Constraints on Free Will or Retrocausality [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2015
Invariant Set (IS) theory is a locally causal ontic theory of physics based on the Cosmological Invariant Set postulate that the universe U can be considered a deterministic dynamical system evolving precisely on a (suitably constructed) fractal ...

Scale-Invariant Learning by Physics Inversion

open access: yesAdvances in Neural Information Processing Systems 35, 2022
Solving inverse problems, such as parameter estimation and optimal control, is a vital part of science. Many experiments repeatedly collect data and rely on machine learning algorithms to quickly infer solutions to the associated inverse problems.

The field of rational constants of the Volterra derivation; pp. 133–135 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2014
We describe the field of rational constants of the four-variable Volterra derivation. Thus, we determine all rational first integrals of its corresponding system of differential equations. Such derivations play a role in population biology, laser physics,

The occurrence frequency of upward ion beams in the auroral zone as a function of altitude using Polar/TIMAS and DE-1/EICS data [PDF]

open access: yesAnnales Geophysicae, 2003
We study the occurrence frequency of upward auroral ion beams as a function of altitude using three years of  Polar/TIMAS ion data combined with 11 years of DE-1/ EICS ion data, in order to reach a complete altitude coverage between 5000 and ...

Parton distributions and new physics searches: the Drell–Yan forward–backward asymmetry as a case study

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We discuss the sensitivity of theoretical predictions of observables used in searches for new physics to parton distributions (PDFs) at large momentum fraction x.

Gauge-invariant and anyonic-symmetric autoregressive neural network for quantum lattice models

open access: yesPhysical 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 ...

The geometry of gauged (super)conformal mechanics

open access: yesJournal of High Energy Physics, 2022
Motivated by recently explored examples, we undertake a systematic study of conformal invariance in one-dimensional sigma models where an isometry group has been gauged.
