ELEMENTARY PARTICLES [PDF]

open access: yesProceedings of the National Academy of Sciences, 1964
In this brief survey I am going to borrow some ideas from a lengthy review prepared in collaboration with Murray Gell-Mann and Arthur Rosenfeld for publication elsewhere.* In the title of our article we have used the term “particle” but have carefully avoided the adjective “elementary”. Had the title of my paper here today been of my choosing, I should

Particle Entrapment in Line Elastohydrodynamic Contacts and the Influence of Intermolecular (van der Waals) Forces

open access: yesLubricants, 2020
A metallic particle passing through concentrated rolling-sliding contacts is often linked to surface damage for particles larger than the available gap. At the instant of particle pinching, force balancing dictates particle entrapment and passing through

The Effect of the Shear Flow on the Morphological Pattern of Particles in an Undercooled Melt

open access: yesMetals, 2022
The effect of shear flow on the morphological pattern of particles in an undercooled melt is studied by using the asymptotic method. The mathematical model of the particle includes the anisotropic interface kinetic undercooling.

Extended Superspheres for Shape Approximation of Near Polyhedral Nanoparticles and a Measure of the Degree of Polyhedrality

open access: yesNanomaterials, 2016
Crystalline nanoparticles or nanoprecipitates with a cubic structure often have near polyhedral shapes composed of low-index planes with {100}, {111} and {110}. To consider such near polyhedral shapes, algebraic formulas of extended superspheres that can

Solid–Liquid Interfacial Properties Related to Ionic Conductivity of Mixtures of Metal Oxide Particles and Lithium Bis(fluorosulfonyl)amide-Sulfone Electrolytes

open access: yesElectrochemistry, 2023
We evaluated and compared the physical properties of electrolyte solutions consisting of lithium bis(fluorosulfonyl)amide and sulfone solvents (molar ratio = 1 : 3) and their mixtures containing aluminum oxide (α-Al2O3) or lithium lanthanum zirconate ...

Cumulant versus jet-like three-particle correlations [PDF]

open access: yes, 2009
Two-particle jet-like azimuthal correlations have revealed intriguing modifications to the away-side of high pt trigger particles in relativistic heavy-ion collisions.

Particle Dispersion and Coherent Fine Scale Eddies in Turbulence

open access: yesJournal of Fluid Science and Technology, 2008
Direct numerical simulations of homogeneous isotropic turbulence laden with particles have been conducted to clarify the relationship between particle dispersion and coherent fine scale eddies in turbulence.

B lifetime measurements with exclusively reconstructed B decays

open access: yes, 2000
Data collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC are used to study the lifetime of the B0 and B+ mesons. The data sample consists of 7.4 fb-1 collected near the Y(4S) resonance. B0 and B+ mesons are fully reconstructed in

Secondary particle clusterization in carbon-carbon collision

open access: yesProceedings of the Mongolian Academy of Sciences, 2018
In the present work, using the hadron clustering algorithm, we have determined the mass of π0 mesons with excellent accuracy by restoring data of the neutral particles which are produced in the collisions of carbons and propane.

Magnetic moments and electromagnetic radii of nucleon and $\Delta(1232)$ in an extended GBE model

open access: yes, 2004
We derive the exchange currents of pseudoscalar, vector, and scalar mesons from Feynman diagrams, and use them to calculate the magnetic form factors of nucleon and $\Delta(1232)$.
