Parton distributions and new physics searches: the Drell–Yan forward–backward asymmetry as a case study [PDF]
European 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.

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.

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 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 ...

Towards critical physics in 2+1d with U(2N )-invariant fermions [PDF]
Journal of High Energy Physics, 2016 Interacting theories of N relativistic fermion flavors in reducible spinor representations in 2+1 spacetime dimensions are formulated on a lattice using domain wall fermions (DWF), for which a U(2N ) global symmetry is recovered in the limit that the ...

NeuPhysics: Editable Neural Geometry and Physics from Monocular Videos [PDF]
Neural Information Processing Systems, 2022 We present a method for learning 3D geometry and physics parameters of a dynamic scene from only a monocular RGB video input. To decouple the learning of underlying scene geometry from dynamic motion, we represent the scene as a time-invariant signed ...

Scale-invariant resonance tagging in multijet events and new physics in Higgs pair production [PDF]
Journal of High Energy Physics, 2013 A bstractWe study resonant pair production of heavy particles in fully hadronic final states by means of jet substructure techniques. We propose a new resonance tagging strategy that smoothly interpolates between the highly boosted and fully resolved ...

Modular invariant models of leptons at level 7 [PDF]
Journal of High Energy Physics, 2020 We consider for the first time level 7 modular invariant flavour models where the lepton mixing originates from the breaking of modular symmetry and couplings responsible for lepton masses are modular forms.
