Cryptocurrency applications of distributed ledger methods such as blockchains are now well established, but their implications for more general topics just beginning to be appreciated. Beyond in finance and banking, new emerging supply chain management, manufacturing, agricultural product tracking, advertising verification, Internet Things, healthcare, the pharmaceutical industry, among others.
Cross sections for deep-inelastic electron scattering from liquid deuterium, gaseous $^{4}\mathrm{He}$, and solid Be, C, Al, Ca, Fe, Ag, Au targets were measured at the Stanford Linear Accelerator Center using electrons with energies ranging 8 to 24.5 GeV. These data cover a range in Bjorken variable $x$ 0.089 0.8, momentum transfer ${Q}^{2}$ 2 15 ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$. The ratios of cross per nucleon...
Microservices are sweeping through cloud design architectures, at once embodying new trends and making use of previous paradigms. This column explores the basis for these in both modern historical standards, sets out a direction future microservices development.
Measurements of the forward-angle differential cross section for elastic electron-proton scattering were made in range momentum transfer from ${Q}^{2}=2.9 \mathrm{to} 31.3$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$ using an electron beam at Stanford Linear Accelerator Center. The data span six orders magnitude section. Combinded statistical and systematic uncertainties measurements ranged 3.6% low ${Q}^{2}$ to 19% high ${Q}^{2}$. These have been used extract proton magnetic form...
The results of a new search for positronium decays into invisible final states are reported. Convincing detection this decay mode would be strong evidence physics beyond the standard model (SM): example, existence extra--dimensions, milli-charged particles, light gauge bosons or mirror particles. Mirror matter could relevant dark candidate. In paper setup and experiment presented. collected sample about $(6.31\ifmmode\pm\else\textpm\fi{}0.28)\ifmmode\times\else\texttimes\fi{}{10}^{6}$...
We have performed absolute measurements of the differential cross section for elastic $e\ensuremath{-}p$ scattering in range momentum transfer from ${Q}^{2}=2.9 \mathrm{to} 31.3$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$. Combined statistical and systematic uncertainties cross-section ranged 3% at low ${Q}^{2}$ to 19% high ${Q}^{2}$. These data been used extract proton magnetic form factor ${G}_{M}^{p}({Q}^{2})$. The results show a smooth decrease ${Q}^{4}{G}_{M}^{p}$ with above...
We present the general properties of multihadron final states produced by e+e− annihilation at center-of-mass energies from 52 to 57 GeV in AMY detector KEK collider TRISTAN. Global shape, inclusive charged-particle, and particle-flow distributions are presented. Our measurements compared with QCD+fragmentation models that use either leading-logarithmic parton-shower evolution or QCD matrix elements parton level, string cluster fragmentation for hadronization.Received 20 November...

From these values an analysis event shapes we deduce a 95%-confidence-level upper limit rate new heavy charge $+\frac{2}{3}e$ or $\ensuremath{-}\frac{1}{3}e$...
We present evidence for the non-Abelian nature of QCD from a study multijet events produced in ${e}^{+}$${e}^{\mathrm{\ensuremath{-}}}$ annihilations \ensuremath{\surd}s =50 to 57 GeV AMY detector at KEK storage ring TRISTAN. A comparison three-jet event fraction TRISTAN DESY PETRA shows that coupling strength ${\ensuremath{\alpha}}_{s}$ decreases with increasing ${Q}^{2}$. In addition, measurements angular distributions four-jet show triple-gluon vertex.
The Dirac form factors ${F}_{1}^{p}$,n of nucleons are analyzed to leading order in the strong coupling constant ${\ensuremath{\alpha}}_{s}$(${Q}^{2}$) and twist using perturbative QCD. effects different choices nucleon distribution amplitude on leading-twist result explored. These results compared with recent experimental data for proton. We show that it is possible fit ${F}_{1}^{p}$ range 10\ensuremath{\le}${Q}^{2}$\ensuremath{\le}30 (GeV/c${)}^{2}$ by evaluating at exact gluon kinematics...
