Quantum Fluctuation Effects on Hyperfragment Formation from Ξ � Absorption at Rest on 12 C
نویسندگان
چکیده
Formation mechanisms of single, twin and double hypernuclei from Ξ− absorption at rest on C are investigated with a refined microscopic transport model that incorporates the recently developed quantal Langevin treatment into antisymmetrized molecular dynamics. With a choice of the fluctuation strength that describes dynamical fragmentation processes in the p + C reaction at 45 MeV quite well, the quantum fluctuations suppress the formation probability of double hyperfragments to around 10%, which is comparable to the experimental data, and the dynamical formation of twin hyperfragment can be described qualitatively.

Suzaku Observations of Near-relativistic Outflows in the Bal Quasar Apm 08279+5255
We present results from three Suzaku observations of the z = 3.91 gravitationally lensed broad absorption line quasar APM 08279+5255. We detect strong and broad absorption at rest-frame energies of . 2 keV (low-energy) and 7–12 keV (high-energy). The detection of these features confirms the results of previous long-exposure (80–90 ks) Chandra and XMM-Newton observations. The low and high-energy...
متن کاملNon - Ergodic Dynamics of the 2 D Random - Phase Sine - Gordon Model : Applications to Vortex - Glass Arrays and Disordered - Substrate Surfaces
The dynamics of the random-phase sine-Gordon model, which describes 2D vortex-glass arrays and crystalline surfaces on disordered substrates, is investigated using the self-consistent Hartree approximation. The fluctuation-dissipation theorem is violated below the critical temperature T c for large time t > t * where t * diverges in the thermodynamic limit. While above T c the averaged autocorr...

To determine the position of quasi-bound state, the triton kinetic energy spectrum in the resonant capture of at rest in is calculated by a coupled-channel procedure. An analysis of theoretical spectra to experimental data yielded the mass and width of , respectively, and, where a possible population of and a small p-orbit capture contribution are taken into account. The calculations show t...
متن کاملEffects of Temperature Fluctuation and Air Aridity on Architecture (Case Study: Dastkand Village Located at Kerman Province)
Constructed upon a height (by footing) or breaking in to the ground, in a building, making a close relation between earth and soil is of great importance. In addition, earth as a prior factor in creation of a shade and residence, plays a crucial role in architecture history. Throughout the different area, earth is paid attention differently: as a source of cool (in China), a source of heat (Cap...
متن کاملControlling of Absorption and Dispersion Spectrum via Electromagnetically Induced Transparency
In this paper we examine the absorption and dispersion properties of a weak probe field via Electromagnetically Induced Transparency (EIT) in a four-level system. It is shown that under certain condition, using this model, the absorption cancellation is appeared and the medium becomes transparent to the weak probe field. It will be shown that the controlling of absorption and dispersion spectru...
