The deconfinement temperature Tc of (2+1)-dimensional SU(2) gauge theory is measured on lattice sizes varying from 2 × 202 to 6 × 602 and with β in the rate 3-9. Approximative scaling is found for β > 6.5 and Tc/√σ = 0.94 ± 0.03 is obtained. This value is in excellent agreement with (3/π) 1 2, as predicted from the breakdown of SU(2) confinement in terms of an effective scalar string theory.

Cross sections for glueball production in hadron-induced reactions are estimated using the gluon-gluon fusion mechanism. For pp → θ(1700, JPC = 2++)X one finds σθ ∼ 2-10 mb in ISR-collider energy range. This cross section should give a clean experimental signal given the substantial KK decay mode observed in ψ → γθ.

An overview is given of Chiral Perturbation Theory and various applications to eta decays. In particular, the main decay η → 3π is discussed at the one-loop level, and estimates of the higher order corrections are given. The importance of p6 and higher order effects in double Dalitz and η → π0γγ decays is pointed out. In all these cases the need for new experimental results is stressed.

We consider exclusive double diffractive production of polarised axial-vector χc(1+) and tensor χc(2+) charmonia in proton-(anti)proton collisions at Tevatron energy. The corresponding amplitudes for these processes are derived within the kt-factorisation approach. Contributions from different polarisation states of axial-vector and tensor charmonia are quantified. Corresponding experimental conse

We present a new model where hard diffraction is an effect of soft gluon rescattering between partons emerging from the hard interaction and the color field of the proton. A resummation to all orders of multiple gluon exchanges leads to an overall color singlet exchange amplitude which reproduces the precise HERA data on diffractive deep inelastic scattering.

Barnarbete har funnits sedan urminnes tider över hela världen. Lagstiftning och andra regler har successivt växt fram i syfte att skydda barn från de hot och faror arbetslivet kan medföra. Jag vill undersöka hur regleringen och utvecklingen kring barnarbete har skett under drygt två sekel samt hur rättsläget ser ut i Sverige idag. Denna uppsats kommer besvara två frågeställningar. Frågeställningar

From a report presented by Public health agency (Folkhälsomyndigheten), it is common amongst female students to experience the study situation as stressful and filled with anxiety. Because of the discussion about female students study situation and the problems it brings is quite old, I experience it to be important for me as a ethnological student and furthermore to contribute with my ethnologica

The aim of this study is to look at the discourses of European identity from two different angles. The first angle is European identity from an EU perspective which EU seeks to create amongst the European citizens. This is studied in the book European Foreign Policy, consisting of legislations and treaties connected to the Common Foreign and Security Policy. The second angle is the images of Europ

This paper reports on multiconfiguration Dirac-Hartree-Fock calculations for intercombination lines in highly charged silicon-like ions. Results for wavelengths, fine structure, transition rates, branching ratios and lifetimes are reported and compared with other theories and experiments. A review of the experimental situation is presented, and deviations from expected smooth trends along the sequ

In this paper we consider a general problem of astrophysical lasersoperating with optical pumping by accidental resonance (PAR) with strongspontaneous emission lines of other elements. The origin of populationinversion and the coefficient of amplification due to the opticalexcitation of atoms (ions) by a four-level scheme with PAR are analyzed.We elucidate conclusively the question of the manifest

The spectroscopic data mercury (Hg) I and Hg II was analyzed from beam-foil spectroscopy. The wavelength was found to be of course fixed and independent of the light source and recording conditions. It was found that if the calculated branching ratio was correct, then the Hg II was an important constituent of fluorescent light tube plasmas. The wavelength region from 40 to 600 nm in overlapping wa

In this contribution we present some preliminary results on the dynamical evolution of two planet systems around stellar hosts evolving from the main sequence to the white dwarf phase. The aim is to study the instabilities triggered by stellar evolution that may bring planets onto the stellar surface or produce planetary scale collisions (hence debris) that could explain the metallic atmospheric p
