We report on experimental transition probabilities for thirteenforbidden [Fe II] lines originating from three different metastable FeIi levels. Radiative lifetimes have been measured of two metastablestates by applying a laser probing technique on a stored ion beam.Branching ratios for the radiative decay channels, i.e. M1 and E2transitions, are derived from observed intensity ratios of forbiddenl

Syftet med uppsatsen är att undersöka hur avtalsmekanismen I AvtL påverkas av den ökande digitaliseringen i samhället. Uppsatsen avser även att undersöka hur den ökade användningen av AI, som på vissa sätt har en nära koppling till digitaliseringen, påverkar avtalsmekanismen. AvtL har länge kritiserats för att vara gammal och ineffektiv men på senare år har mer positiva ståndpunkter yttrats. Uppsa

In the past, development of the PYTHIA event generator has mainly concentrated on the physics of proton–proton collisions at high energies, as this is the most important case to modern high energy physics experiments. However, there are situations where more generic beam configurations are relevant. This thesis presents implementations and applications of such processes in PYTHIA. The two applicat

Planets with radii between that of the Earth and Neptune (hereafter referred to as ‘sub-Neptunes’) are found in close-in orbits around more than half of all Sun-like stars 1,2. However, their composition, formation and evolution remain poorly understood 3. The study of multiplanetary systems offers an opportunity to investigate the outcomes of planet formation and evolution while controlling for i

We discuss whether the enhancement in the diphoton final state at Mgg = 750 GeV, observed recently by the ATLAS and CMS Collaborations could be a neutral pseudoscalar technipion π∼0. We considered two distinct minimal models for the dynamical electroweak symmetry breaking. Here we concentrate only on two-flavor vector-like technicolor model and we assume that the two-photon fusion is a dominant pr

Most of the traditional technicolor-based models are known to be in a strong tension with the electroweak precision tests. We show that this serious issue is naturally cured in strongly coupled sectors with chiral-symmetric vectorlike gauge interactions in the framework of the gauged linear sigma model. We discuss possible phenomenological implications of such a nonstandard chiral-symmetric techni

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 2,873 new measurements from 758 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark ph

In a single theoretical framework, real and virtual photon interactions are modeled for gamma-p and gamma-gamma collisions. The description covers aspects from the production of jets to total cross sections, where special emphasis is put on the range of uncertainty in the modeling of a resolved photon component. Our approach extends on a model for photoproduction, where the total cross section is

Värdering av ekosystemtjänster i byggbranschen – har det någon effekt? I takt med att byggandet ökar blir de gröna ytorna i staden mindre och mindre. I Sverige har en rad olika initiativ tagits för att kompensera för förlorad natur i samband med bebyggelse. Men vilken effekt har dessa initiativ? I denna studie undersöks ett verktyg utvecklat för att bevara, stärka eller kompensera för ekosystemtjUrbanisation is increasing the pressure to exploit green and blue spaces in the city. To preserve these spaces and the ecosystem services they provide, there is a need to change the way we plan and build cities. One way of doing this is to include valuation of ecosystem services in the planning process. Many different tools with the purpose to do this have been developed. The purpose of this stud
