Experimental Search for W / Z Pairs and Higgs Bosons at Very High-Energy Hadron Hadron Colliders

Conference paper (other academic/artistic)abstract
- We study, from an experimental point of view, the main ways to detect standard high mass Higgs bosons (from 300 Gev up to about 1 TeV) when they decay into W- and Z- pairs at the SSC. We also consider the corresponding W- and Z”-pair continuum which may itself provide interesting physics, and we pay some attention to the case of an intermediate mass charged Higgs decaying into rvr, (met =300 GeV). We first explain why and how high energy pp colliders may search for Higgs’ and we compare their possible performances to those of the e+e- and ep colliders at all possible m-s scale (from few tens of GeV’s up to 1 TeV). We then estimate the rates of the signals and the main backgrounds. Wede5ne the main characteristics of these events as reproduced by M.C. generators (especially implemented with these processes) and simulated through an idealiied In fine-grained calorimeter. A trigger strategy for W- and Z-pairs is derived from this study.

Undersökning av olika träbaserade skivors "mögelbenägenhet"
- 1987
-
Reports (other academic/artistic)abstract
- Undersökningarna visar att samtliga testade skivtyper (fiberskivor, spånskivor, plywood, gipsskivor, dessutom splintved av tall och gran samt splintved av tall behandlad med natriumbenzoat) i större eller mindre utsträckning kunde angripas av mögel och blånadssvampar vid accelererade provningar i laboratorium. I stort sett möglade spånskivor fortast, därnäst fiberskivor och sedan plywood.

A Discussion of Adaptive Stabilization and Robust Adaptive Control
- 1988
-
Reports (other academic/artistic)abstract
- This paper presents an algorithm for stabilizing a linear system with bounded disturbances, by a sampled-data regulator. The prior knowledge required is that the system has finite order and bounded disturbances. Bounds on the disturbances and on the order of the system need not be known.The implications of this technical result on theoretical convergence issues in adaptive control are also discussed.

Analysis of a Glucose-Containing Tetrasaccharide by High-Performance Liquid Affinity Chromatography
- 1989
-
In: Analytical Biochemistry. - : Elsevier BV. - 0003-2697 .- 1096-0309. ; 182:1, s. 48-53
-
Journal article (peer-reviewed)abstract
- In the present work we have explored conditions for using a pulsed amperometric detector for on-line analysis of oligosaccharides eluted from a high-performance liquid affinity chromatography column. A monoclonal antibody that specifically binds a glucose-containing oligosaccharide is coupled to a SelectiSphere-10-activated tresyl column. The system is eluted isocratically and easily detects 10 ng of the oligosaccharide with a linear response up to 250 ng. Analysis of both serum and urine samples from normal individuals and patients with acute pancreatitis gives a single retarded peak with a retention time identical to that of authentic (Glc)4. Retarded material pooled from several analyses of urine was positively identified as (Glc)4 by GC-MS analysis. As this method requires little cleanup and no chemical derivitization of the sample and is performed rapidly (less than 20 min) at sensitivities of at least 10μg/liter in biological fluids, it represents a substantial improvement over previous GC-MS, radioimmunoassay, and enzyme-linked immunoadsorbent assay methods used to determine (Glc)4.

A study of the natural and induced hydrophobicity of some sulphide minerals by collectorless flotation
- 1989
-
In: Processing of complex ores. - New York : Pergamon Press. - 008037283X ; , s. 3-17
-
Conference paper (peer-reviewed)abstract
- The native and induced surface hydrophobicity of a number of natural sulfide minerals (galena, pyrite) were investigated by flotation tests in the absence and presence of EDTA. The dissolution behaviour of the minerals in EDTA solutions was studied as a function of pH and EDTA concentration. With the exception of sphalerite, the flotation and dissolution of the tested minerals in EDTA solutions depend strongly on the pH values and EDTA concentration. In general, at a proper EDTA concentration, low flotation and small amount of released metal species were observed up to pH 5 and > 10. In the range of pH 6-10, both flotation recovery and the dissolution of the minerals exhibited a plateau, and the amount of released metal species increased with increasing EDTA concentration. The floatability first increases with an increase in EDTA concentration; however, a further increase in concentration ( > 10 exp --3 M ) leads to a significant decrease in flotation recovery. Zeta-potential measurements show that, in the presence of EDTA, the iep of the sulfide minerals is shifted considerably to lower pH values. These results are used to discuss the surface hydrophobicity of the sulfide minerals.
