Elementary particles with continuous spin [PDF]

open access: yesInternational Journal of Modern Physics A, 2017
Classical results and recent developments on the theoretical description of elementary particles with “continuous” spin are reviewed. At free level, these fields are described by unitary irreducible representations of the isometry group (either Poincaré or anti-de Sitter group) with an infinite number of physical degrees of freedom per space–time ...

On a New Elementary Particle from the Disintegration of the Symplectic 't Hooft-Veltman-Wilson Fractal Spacetime

open access: yes, 2014
't Hooft-Veltman Wilson dimensional regularization depends crucially upon Borel summability which entails strong links to the modern mathematical theory of transfinite sets and consequently to the fractal-Cantorian spacetime proposal of Ord-Nottale-El

Spin-orbital motion and Thomas precession in the classical and quantum theories [PDF]

open access: yes, 2001
The motion of a magnetic spin particle in electromagnetic fields is considered on the basis of general principles of the classical relativistic theory.

Development of High-Granularity Dual-Readout Calorimetry with psec Timing [PDF]

open access: yesEPJ Web of Conferences
Dual-readout and particle flow algorithm (PFA) are technologies proposed for precise jet energy measurement in future colliders. While PFA requires highly granular calorimeters, dual-readout has mainly been used with fiber-based calorimeters that do not ...

Gauge Theory of elementary particle physics

open access: yes, 1984
This is a practical introduction to the principal ideas in gauge theory and their applications to elementary particle physics. It explains technique and methodology with simple exposition backed up by many illustrative examples. Derivations, some of well

Lattice Simulations of the Thermodynamics of Strongly Interacting Elementary Particles and the Exploration of New Phases of Matter in Relativistic Heavy Ion Collisions [PDF]

open access: yes, 2006
At high temperatures or densities matter formed by strongly interacting elementary particles (hadronic matter) is expected to undergo a transition to a new form of matter - the quark gluon plasma - in which elementary particles (quarks and gluons) are no

Ultrafine particle concentrations and exposures in six elementary school classrooms in northern California.

open access: yesIndoor Air: International Journal of Indoor Environment and Health, 2011
UNLABELLED Potential health risks may result from environmental exposure to ultrafine particles (UFP), i.e., those smaller than 0.1 μm in diameter. One important exposure setting that has received relatively little attention is school classrooms. We made

Introduction to the Quantum Theory of Elementary Cycles: The Emergence of Space, Time and Quantum

open access: yes, 2016
Elementary Cycles Theory is a self-consistent, unified formulation of quantum and relativistic physics. Here we introduce its basic quantum aspects.

ELEMENTARY PARTICLE INTERACTIONS [PDF]

open access: yes, 1989
The High-Energy Elementary Particle Interactions group at UT during the last three years worked on the following directions and projects: Collider-based Particle Physics; Neutrino Physics, particularly participation in “NOνA”, “Double Chooz”, and “KamLAND” neutrino experiments; and Theory, including Scattering amplitudes, Quark-gluon plasma ...

Could Only Fermions Be Elementary? [PDF]

open access: yes, 2004
In standard Poincare and anti de Sitter SO(2,3) invariant theories, antiparticles are related to negative energy solutions of covariant equations while independent positive energy unitary irreducible representations (UIRs) of the symmetry group are used ...
