Transport Simulations with π and ∆ In - Medium Properties †
نویسنده
چکیده
Transport simulations including in-medium properties derived in a microscopic π+NN−1+ ∆N−1 model in infinite nuclear matter are presented. In-medium pion dispersion relations, partial ∆ decay widths, pion absorption cross sections and ∆ cross sections are incorporated into the transport description by means of a local-density approximation. Strong modifications of π and ∆ production and absorption rates are found, but only small effects on pion observables. PACS: 25.75.Dw, 25.75.-q, 24.10.Cn, 13.75.Gx

Effects of Spin-Isospin Modes in Transport Simulations
In-medium properties derived for nuclear matter in a microscopic π+NN+∆N model are incorporated into transport simulations of nuclear collisions by means of a local-density approximation and by utilizing a local medium frame. Certain features of the transport results differ from those based on the corresponding vacuum properties. Comparisons of the π and ∆ production rates, as well as pion ener...

متن کاملA theoretical study on halogen-π interactions: X-C2-Y…C8H8 complexes
M06-2X functional was employed to study halogen-π interactions in X-C2-Y…C8H8 complexes (X, Y=H, F, Cl, and Br). In fact, interactions of mono- or di-halogenated acetylenes and planar cyclooctatetraene as an anti-aromatic π system were considered. Relationship between binding energies of the complexes and charge transfer effects was investigated. Also, electronic charge density values were calc...
متن کاملTransport Property Estimation of Non-Uniform Porous Media
In this work a glass micromodel which its grains and pores are non-uniform in size, shape and distribution is considered as porous medium. A two-dimensional random network model of micromodel with non-uniform pores has been constructed. The non-uniformity of porous model is achieved by assigning parametric distribution functions to pores throat and pores length, which was measured using ima...
متن کاملInvestigating the Effects of Cold Bulge Forming Speed on Thickness Variation and Mechanical Properties of Aluminum Alloys: Experimental and Numerical
In this work, cold bulge forming of an Aluminium-Magnesium (Al-Mg) sheet with a solid bulging medium is performed experimentally and numerically. Mechanical properties and thickness variations of Al-Mg sheet are evaluated before and after the forming process. The results indicated that the Al-Mg sheet has taken the desired shape without necking using the cold bulge forming process. Also, the...
