The production of d′ dibaryons in heavy ion collisions due to the elementary process NN → d′π is considered. The NN → d′π cross section is estimated using the vacuum d′ width Γd′ ≈ 0.5 MeV extracted from data on the double charge exchange reactions on nuclei. The d′ production rate per single collision of heavy ions is estimated at an incident beam energy of 1 A·GeV within the framework of the ...

where the field strength F a μν = ∂μA a ν − ∂νA a μ + gfAμA c ν , z = y− x and P denotes path ordering of the exponential. In general, the gauge invariant field strength correlator could be defined with an arbitrary gauge string connecting the end points x and y, but in this work we shall restrict ourselves to a straight line. It is the basic ingredient in the stochastic model of the QCD vacuum...

in the present work, deoxidation and refining of 316lvm steel (low carbon vacuum melted) during the vacuum induction melting process was studied. this grade of stainless steel is one of the most important materials in medical applications. vacuum deoxidation by carbon is the first stage of 316lvm stainless steel production process. in this stage, aluminum must be absent to avoid killing the c-o...

The production of d ′ dibaryons in heavy ion collisions due to the elementary process N N → d ′ π is considered. The N N → d ′ π cross section is estimated using the vacuum d ′ width Γ d ′ ≈ 0.5 MeV extracted from data on the double charge exchange reactions on nuclei.

purpose: to evaluate the effect of vacuum and flow rate on endothelial cell loss after high versus low vacuum phacoemulsification. methods: this randomized clinical trial was performed on 60 eyes of 60 patients with moderate lens opacity (nuclear sclerosis 3+). all surgeries were performed by one experienced surgeon using stop and chop technique with sovereign white star machine (amo). patients...

Building on the principles of structure-oriented lumping (SOL), chemistry-oriented lumping methods have been developed to describe the composition in tandem with the hydro-processing chemistry of heavy oils such as vacuum residue, de-asphalted oil, tar and bitumen. Recent advances in analytical chemistry have provided the necessary fundamental insights that are required to develop such models. ...

A study of collective behavior in heavy ion collisions provides one of the most sensitive and promising probes for investigation of possible formation of new extreme state of strong interacting matter and elucidating its properties. Systematic of experimental results for final state azimuthal anisotropy is presented for heavy ion interactions at RHIC. Experimental data for azimuthal anisotropy ...
