Bounce Cosmology in a Locally Scale Invariant Physics with a U(1) Symmetry [PDF]
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.

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

Scale-invariant dynamical fluctuations in jet physics [PDF]
The European Physical Journal C, 1999 An interpretation of scale-invariant multiplicity fluctuations inside hadronic jets is presented. It is based on the branching mechanism with the angular ordering of soft partons in sequential branchings. A relationship with fractal distributions is demonstrated.

Geometrical Invariants of Matter Motion in Physics [PDF]
, 2005 This paper defines the spacetime geometry attached with observor as vacuum geometry (it defines the idea physical measurement geometry) and the spacetime geometry attached with matter as spacetime geometry. The initial spacetime geometry attached with matter is taken as refference geometry (named as initial co-moving coordinator system), and the ...

Model-Independent Searches for New Physics in Multi-Body Invariant Masses
Universe, 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

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

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