Use of residual-state decay γ-rays could be a powerful tool in the study of photonuclear reactions. The practicality of this technique in a tagged-photon experiment is demonstrated for the first time with data on the 12 C(γ, p) reaction.
Capturing progression in students’ formal knowledge and employability skills is essential in higher education but evokes questions concerning how to assess and monitor progression. While methods for capturing students’ formal knowledge progression have traditionally been at the forefront, methods for capturing employability skills have been less researched within higher education. The aim of this
Time-of-flight mass spectrometry is used to study the interaction of free C60 molecules with ultrashort high power Ti:sapphire laser pulses. Ionization and fragmentation of C60 by ultrashort high-intensity laser pulses occur predominantly via plasmon excitation. Single and double excitation of collective charge oscillation is observed by remarkably large number of photons. The difference between a
Context. Although more than 2000 brown dwarfs have been detected to date, mainly from direct imaging, their characterisation is difficult due to their faintness and model-dependent results. In the case of transiting brown dwarfs, however, it is possible to make direct high-precision observations.Aims: Our aim is to investigate the nature and formation of brown dwarfs by adding a new well-character
An outline is presented here of the Po Valley Fog Experiment 1989, carried out within the EUROTRAC‐GCE project. This experiment is a joint effort by several European research groups from 5 countries. The physical and chemical behaviour of the fog multiphase system was studied experimentally following the temporal evolution of the relevant chemical species in the different phases (gas, droplet, int
An overview of the cultural significance of Vesuvius during the eighteenth century and Romantic period.
This chapter of the 'Flavor in the era of LHC' workshop report discusses flavor-related issues in the production and decays of heavy states at the LHC at high momentum transfer Q, both from the experimental and the theoretical perspective. We review top quark physics, and discuss the flavor aspects of several extensions of the standard model, such as supersymmetry, little Higgs models or models wi
The importance of Monte Carlo event generation for future super colliders is discussed and a brief overview of available programs is given. To emphasize the need for different models of the hadronization process, an example of a measurement is presented where fragmentation effects ‘destroys’ an effect predicted by perturbative QCD also at very high energies. Finally the use of modern programming t
We present preliminary results of a Monte Carlo algorithm that provides a faithful representation of the BDMPS-Z formalism for highly energetic partons interacting in dense QCD matter. In the incoherent limit, the evolution is governed by the probabilities for elastic and inelastic scattering of the highly energetic parton with target constituents in the dense QCD matter. A dynamically evolving fo
In this paper the current bounds on the CKM matrix elements |V td|, |Vts| and |Vtb| from direct measurements are discussed and an improved "model-independent" analysis is proposed.

BackgroundIn light of the opioid epidemic in the United States, there is growing concern about the use of opioids in Sweden as it may lead to misuse and overuse and, in turn, severe public health problems. However, little is known about the distribution of opioid use across different demographic and socioeconomic dimensions in the Swedish general population. Therefore, we applied an intersectional
This paper discusses modern organizational meetings in the public sector, with a focus on time, specifically the planning and scheduling of time among managers. In this qualitative analysis, data were gathered through an ethnographic study of managers in several public organizations, all in Sweden. During interviews and field observations, managers told about their time work involving strategies f
Jet quenching is one of the major discoveries of the heavy-ion program at Rhic. While there is a wealth of data from Rhic that will soon be supplemented with measurements at the Lhc, on the theoretical side the situation is less clear. A thorough understanding of jet quenching is, however, beneficial, as it is expected that medium-induced modifications of jets allow one to characterise properties
A thorough understanding of jet quenching on the basis of multi-particle final states and jet observables requires new theoretical tools. This talk summarizes the status and prospects of the theoretical description of jet quenching in terms of Monte Carlo generators.
Extending the use of Monte Carlo (MC) event generators to jets in nuclear collisions requires a probabilistic implementation of the non-abelian LPM effect. We demonstrate that a local, probabilistic MC implementation based on the concept of formation times can account fully for the LPM-effect. The main features of the analytically known eikonal and collinear approximation can be reproduced, but we
The Monte Carlo model JEWEL 1.0 (Jet Evolution With Energy Loss) simulates parton shower evolution in the presence of a dense QCD medium. In its current form medium interactions are modelled as elastic scattering based on perturbative matrix elements and a simple prescription for medium induced gluon radiation. The parton shower is interfaced with a hadronisation model. In the absence of medium ef
Digitalization has been incorporated into nearly all levels of life in Sweden, including the provision of healthcare service. Accompanied by political strategies that incorporate liberal market logic into public sectors, medicines are made accessible through multiple purchasing channels, especially on the Internet. In this presentation, Rui Liu gives an account of the emergence of a grey health ma
