Geant4 is a software toolkit for the simulation of passage particles through matter. It used by large number experiments and projects in variety application domains, including high energy physics, astrophysics space science, medical physics radiation protection. Its functionality modeling capabilities continue to be extended, while its performance enhanced. An overview recent developments diverse areas presented. These include optimization complex setups; improvements propagation fields; new...
Geant4 is a software toolkit for the simulation of passage particles through matter. It used by large number experiments and projects in variety application domains, including high energy physics, astrophysics space science, medical physics radiation protection. Over past several years, major changes have been made to order accommodate needs these user communities, efficiently exploit growth computing power available advances technology. The adaptation multithreading, detector modeling...
An overview of the electromagnetic (EM) physics Geant4 toolkit is presented.Two sets EM models are available: "Standard" initially focused on high energy (HEP) while "Low-energy" was developed for medical, space and other applications.The provide a faster computation but less accurate keV energies, more CPU time consuming.A common interface to has been allowing natural combination ultra-relativistic, relativistic low-energy same run providing both precision performance.Due this migration...

The axion provides a solution for the strong CP problem and is one of leading candidates dark matter. This paper proposes an detection scheme based on quantum nondemolition magnon, i.e., quanta collective spin excitations in solid, which expected to be excited by axion-electron interaction predicted Dine-Fischer-Srednicki-Zhitnitsky (DFSZ) model. prototype detector composed ferrimagnetic sphere as electronic target superconducting qubit. Both these are embedded inside microwave cavity, leads...
A 16-channel time-to-digital-converter (TDC) module with better than 15-ps resolution was developed in a TKO package. The circuit has also very low temperature coefficient (typically 40 ppm/ degrees C), so that the requirement on ambient is not critical despite its ultrahigh resolution. can withstand repetition rate of 400 kHz maximum one count error 12-bit full scale. Twelve TDC modules (192 channels) have been operation for over half year at TRISTAN VENUS experiment without any failure.<...
Yogurt is made by fermenting milk with 2 lactic acid bacteria, Lactobacillus delbrueckii ssp. bulgaricus and Streptococcus thermophilus. To comprehensively understand the protocooperation mechanism between S. thermophilus L. in yogurt fermentation, we examined 24 combinations of cocultures comprising 7 fast- or slow-acidifying strains 6 strains. Furthermore, 3 NADH oxidase (Nox)-deficient mutants (Δnox) one pyruvate formate-lyase deficient mutant (ΔpflB) were used to evaluate factor that...
A search for sequential charged leptons decaying into massive neutrinos has been performed at ${E}_{\mathrm{c}.\mathrm{m}.}=56$ GeV the KEK colliding-beam accelerator TRISTAN. We have found no evidence production of heavy an integrated luminosity 5.3 ${\mathrm{pb}}^{\ensuremath{-}1}$. stable was also conducted yielding null results. new mass limit on obtained as a function associated neutrinos.
We have studied four-jet angular distributions using data collected with the VENUS detector at KEK ${\mathit{e}}^{+}$${\mathit{e}}^{\mathrm{\ensuremath{-}}}$ collider TRISTAN c.m. energies between 54 and 64 GeV. The obseved are consistent QCD, but inconsistent Abelian gluon model 5% significance level. further obtained 95%-confidence experimental bounds on fundamental parameters of SU(${\mathit{N}}_{\mathit{c}}$) local color symmetry.
A result of the search for top quark in e + - annihilation into hadrons at \(\sqrt{s}=50\) GeV is presented. The experiment has been perforrnxed using VENUS detector TRISTAN. No evidence found production quark. From study event shape multihadron events, upper limit cross section to be 16 pb thcc 95% confidence level.
