Portfolio "International "Studieren" - Internationalisierung des Curriculums durch interkulturelle Kompetenz und Integration

Dieser Beitrag beschreibt die Konzeption und Einführung eines ePortfolios mit dem Leitthema »International Studieren« als Teil eines Projekts zur Integration ausländischer Studierender und Internationalisierung des Studienalltags. Die Konstellation bei diesem Teilprojekt beinhaltete, dass das Portfolio »International Studieren« im Dezernat Studium und Lehre der Universität Tübingen, also einer zentralen Verwaltungseinheit, konzipiert wurde, um dann dezentral in Lehrveranstaltungen in den Fakultäten umgesetzt zu werden. Daher bezieht sich dieser Erfahrungsbericht einerseits auf die strukturell-organisationalen Rahmenbedingungen der Portfolio-Einführung und andererseits auf die didaktischen Erfahrungen, die bei einem erstmaligen Portfolio-Einsatz in einer Lehrveranstaltung gemacht wurden. Die Erkenntnisse aus den ePortfolio-Piloten »International Studieren« sind übertragbar auf Portfolio-Vorhaben, mit denen die folgenden und angrenzende Ziele verfolgt werden: - Steuerung der Orientierungsphase beim Einstieg in das Hochschulstudium - Begleitung eines kontinuierlichen Lernprozesses (mit Möglichkeit der Verteilung von Prüfungslast) - Verankerung von Querschnittsthemen wie Internationalisierung und Integration, aber auch z.B. Nachhaltigkeit, Diversity Human Development etc, - Integration von Schlüsselqualifikationen in die Fachlehre - Angebot von niederschwelligen Schreibanlässen als Einstieg in das akademische Schreiben - Lernziele für Studierende transparent machen

Multiplicity dependence of light (anti-)nuclei production in p–Pb collisions at sNN=5.02 TeV

The measurement of the deuteron and anti-deuteron production in the rapidity range −1 < y < 0 as a function of transverse momentum and event multiplicity in p–Pb collisions at √sNN = 5.02 TeV is presented. (Anti-)deuterons are identified via their specific energy loss dE/dx and via their time-of- flight. Their production in p–Pb collisions is compared to pp and Pb–Pb collisions and is discussed within the context of thermal and coalescence models. The ratio of integrated yields of deuterons to protons (d/p) shows a significant increase as a function of the charged-particle multiplicity of the event starting from values similar to those observed in pp collisions at low multiplicities and approaching those observed in Pb–Pb collisions at high multiplicities. The mean transverse particle momenta are extracted from the deuteron spectra and the values are similar to those obtained for p and particles. Thus, deuteron spectra do not follow mass ordering. This behaviour is in contrast to the trend observed for non-composite particles in p–Pb collisions. In addition, the production of the rare 3He and 3He nuclei has been studied. The spectrum corresponding to all non-single diffractive p-Pb collisions is obtained in the rapidity window −1 < y < 0 and the pT-integrated yield dN/dy is extracted. It is found that the yields of protons, deuterons, and 3He, normalised by the spin degeneracy factor, follow an exponential decrease with mass number

Production of pions, kaons, (anti-)protons and ϕ\phi mesons in Xe–Xe collisions at sNN\sqrt{s_{\mathrm{NN}}} = 5.44 TeV

The first measurement of the production of pions, kaons, (anti-)protons and $\phi$ mesons at midrapidity in Xe–Xe collisions at $\sqrt{s_{\mathrm{NN}}} = 5.44~\text {TeV}$ is presented. Transverse momentum ($p_{\mathrm{T}}$) spectra and $p_{\mathrm{T}}$-integrated yields are extracted in several centrality intervals bridging from p–Pb to mid-central Pb–Pb collisions in terms of final-state multiplicity. The study of Xe–Xe and Pb–Pb collisions allows systems at similar charged-particle multiplicities but with different initial geometrical eccentricities to be investigated. A detailed comparison of the spectral shapes in the two systems reveals an opposite behaviour for radial and elliptic flow. In particular, this study shows that the radial flow does not depend on the colliding system when compared at similar charged-particle multiplicity. In terms of hadron chemistry, the previously observed smooth evolution of particle ratios with multiplicity from small to large collision systems is also found to hold in Xe–Xe. In addition, our results confirm that two remarkable features of particle production at LHC energies are also valid in the collision of medium-sized nuclei: the lower proton-to-pion ratio with respect to the thermal model expectations and the increase of the $\phi$-to-pion ratio with increasing final-state multiplicity

Multiplicity dependence of light (anti-)nuclei production in p-Pb collisions at sNN\sqrt{s_{\rm{NN}}} = 5.02 TeV

International audienceThe measurement of the deuteron and anti-deuteron production in the rapidity range −1<y<0 as a function of transverse momentum and event multiplicity in p–Pb collisions at sNN = 5.02 TeV is presented. (Anti-)deuterons are identified via their specific energy loss dE/dx and via their time-of-flight. Their production in p–Pb collisions is compared to pp and Pb–Pb collisions and is discussed within the context of thermal and coalescence models. The ratio of integrated yields of deuterons to protons (d/p) shows a significant increase as a function of the charged-particle multiplicity of the event starting from values similar to those observed in pp collisions at low multiplicities and approaching those observed in Pb–Pb collisions at high multiplicities. The mean transverse particle momenta are extracted from the deuteron spectra and the values are similar to those obtained for p and Λ particles. Thus, deuteron spectra do not follow mass ordering. This behaviour is in contrast to the trend observed for non-composite particles in p–Pb collisions. In addition, the production of the rare He3 and He‾3 nuclei has been studied. The spectrum corresponding to all non-single diffractive p-Pb collisions is obtained in the rapidity window −1<y<0 and the pT -integrated yield d N /d y is extracted. It is found that the yields of protons, deuterons, and He3 , normalised by the spin degeneracy factor, follow an exponential decrease with mass number

Production of light (anti)nuclei in pp collisions at s \sqrt{s} = 13 TeV

Understanding the production mechanism of light (anti)nuclei is one of the key challenges of nuclear physics and has important consequences for astrophysics, since it provides an input for indirect dark-matter searches in space. In this paper, the latest results about the production of light (anti)nuclei in pp collisions at $\sqrt{s}$ = 13 TeV are presented, focusing on the comparison with the predictions of coalescence and thermal models. For the first time, the coalescence parameters B$_{2}$ for deuterons and B$_{3}$ for helions are compared with parameter-free theoretical predictions that are directly constrained by the femtoscopic measurement of the source radius in the same event class. A fair description of the data with a Gaussian wave function is observed for both deuteron and helion, supporting the coalescence mechanism for the production of light (anti)nuclei in pp collisions. This method paves the way for future investigations of the internal structure of more complex nuclear clusters, including the hypertriton.[graphic not available: see fulltext
