The polarization of Λ and Λ¯ hyperons along the beam direction has been measured relative to the second and third harmonic event planes in isobar Ru+Ru and Zr+Zr collisions at sNN−−−−√ = 200 GeV. The second harmonic results follow the emission angle dependence as expected due to elliptic flow, similar to that observed in Au+Au collisions. The polarization relative to the third harmonic event plane, measured for the first time, deviates from zero with 4.8σ significance in 20-60\% centrality for 1.1<pT<6.0 GeV/c and exhibits a similar dependence on the emission angle. These results indicate the formation of a complex vortical structure in the system that follows higher harmonic anisotropic flow originating from the initial density fluctuations. The amplitudes of the sine modulation for the second and third harmonic results are comparable in magnitude, increase from central to peripheral collisions, and show a mild pT dependence. While the centrality dependence, except in peripheral collisions, is qualitatively consistent with hydrodynamic model calculations including thermal vorticity and shear contributions, the shape of the pT dependence is very different. Comparison to previous measurements at RHIC and the LHC for the second-order harmonic results shows little dependence on the collision system size and collision energy.
The most precise measurements to date of the 3ΛH lifetime τ and Λ separation energy BΛ are obtained using the data sample of Pb-Pb collisions at √sNN = 5.02 TeV collected by ALICE at the LHC. The 3ΛH is reconstructed via its charged two-body mesonic decay channel (3ΛH→ 3He + π− and the charge-conjugate process). The measured values τ=[253±11 (stat.)±6 (syst.)] ps and BΛ=[72±63 (stat.)±35 (syst.)] keV are compatible with predictions from effective field theories and conclusively confirm that the 3ΛH is a weakly-bound system.

With this volume, the editors Katharina Edtstadler, Sandra Folie, and Gianna Zocco propose an extension of the traditional conception of imagology as a theory and method for studying the cultural construction and literary representation of national, usually European characters. Consisting of an instructive introduction and 21 articles, the book relates this sub-field of comparative literature to contemporary political developments and enriches it with new interdisciplinary, transnational, intersectional, and intermedial perspectives. The contributions offer [1] a reconsideration and update of the field's methods, genres, and theoretical frames; [2] trans-/post-national, migratory, and marginalized perspectives beyond the European nation-state; [3] insights into geopolitical dichotomies such as Orient/Occident; [4] intersectional approaches considering the entanglements of national images with notions of age, class, gender, sexuality, and ethnicity/race; [5] investigations of the role of national images in visual narratives and music.
