Nuclear transparency from quasielastic A(e,e'p) reactions uo to Q^2=8.1 (GeV/c)^2

The quasielastic (e,e$^\prime$p) reaction was studied on targets of deuterium, carbon, and iron up to a value of momentum transfer $Q^2$ of 8.1 (GeV/c)$^2$. A nuclear transparency was determined by comparing the data to calculations in the Plane-Wave Impulse Approximation. The dependence of the nuclear transparency on $Q^2$ and the mass number $A$ was investigated in a search for the onset of the Color Transparency phenomenon. We find no evidence for the onset of Color Transparency within our range of $Q^2$. A fit to the world's nuclear transparency data reflects the energy dependence of the free proton-nucleon cross section.Comment: 11 pages, 6 figure

Study on media plurality and diversity online : final report

Published online: 16 September 2022The Study on Media Plurality and Diversity Online investigates the value of safeguarding media pluralism and diversity online, focusing on (i) the prominence and discoverability of general interest content and services, and on (ii) market plurality and the concentration of economic resources. With a focus on Europe, the project is funded by a tender from the European Commission to produce a study on Media Plurality and Diversity Online and involves four partner universities: CMPF (EUI); CiTiP (Centre for Information Technology and Intellectual Property) of KU Leuven; the Institute for Information Law of the University of Amsterdam (IViR/UvA); imec-SMIT-Vrije Universiteit Brussel. The purpose of the assignment was to describe, analyse and evaluate the existing regulatory and business practices in the two areas mentioned above, and finally to elaborate some policy recommendations. Data were collected from the database of the Media Pluralism Monitor (CMPF) and through desk research, online consultations and interviews with stakeholders. The contractor was able to call on a network of national experts across the Member States to support this work
