Comparison between simulated and observed LHC beam backgrounds in the ATLAS experiment at E beam =4 TeV
2018
Results of dedicated Monte Carlo simulations of beam-induced background (BIB) in the ATLAS experiment at the Large Hadron Collider (LHC) are presented and compared with data recorded in 2012. During normal physics operation this background arises mainly from scattering of the 4 TeV protons on residual gas in the beam pipe. Methods of reconstructing the BIB signals in the ATLAS detector, developed and implemented in the simulation chain based on the FLUKA Monte Carlo simulation package, are described. The interaction rates are determined from the residual gas pressure distribution in the LHC ring in order to set an absolute scale on the predicted rates of BIB so that they can be compared qua…
New high-sensitivity searches for neutrons converting into antineutrons and/or sterile neutrons at the HIBEAM/NNBAR experiment at the European Spalla…
2021
Abstract The violation of baryon number, B , is an essential ingredient for the preferential creation of matter over antimatter needed to account for the observed baryon asymmetry in the Universe. However, such a process has yet to be experimentally observed. The HIBEAM/NNBAR program is a proposed two-stage experiment at the European Spallation Source to search for baryon number violation. The program will include high-sensitivity searches for processes that violate baryon number by one or two units: free neutron–antineutron oscillation ( n → n ̄ ) via mixing, neutron–antineutron oscillation via regeneration from a sterile neutron state ( n → [ n ′ , n ̄ ′ ] → n ̄ ), and neutron disappearan…

Measurements of the top quark branching ratios into channels with leptons and quarks with the ATLAS detector
2015
Measurements of the branching ratios of top quark decays into leptons and jets using events with t[bar over t] (top antitop) pairs are reported. Events were recorded with the ATLAS detector at the LHC in pp collisions at a center-of-mass energy of 7 TeV. The collected data sample corresponds to an integrated luminosity of 4.6 fb[superscript −1]. The measured top quark branching ratios agree with the Standard Model predictions within the measurement uncertainties of a few percent.
Oikeudenmukaisuus sisäsyntyisinä oikeuksina ja kasvatus oikeudenmukaisuuteen dialogisen pluralismin kontekstissa : näkökulmia ja tulkintoja Nicholas …
2017
The study offers a philosophical analysis of Nicholas Wolterstorff’s theory of justice and education for justice. Crucial aspects of Wolterstorff’s theory are his understanding of justice as inherent rights and justice as inherent worth. Interrelated to this are the concepts of life-goods, well-being and the good life. Within this framework of rights grounded in worth, the notions of natural human rights and human dignity occupy a special position. These notions in turn form the philosophical foundation and implications for education for justice. The study is divided into two parts. The first part delves into the notion of justice as inherent rights. The key aspects addressed in this sectio…
Reporting in Conflict Zones in Pakistan: Risks and Challenges for Fixers
2020
As a backbone of reporting in war and conflicts, fixers offer essential assistance to the foreign correspondent in conflict zones, also in Pakistan. With valuable local knowledge and contacts, fixers can arrange travel to secure entry of foreign correspondents into conflict zones in addition to securing interviews with otherwise unattainable figures, while offering reliable translation services. Pakistani media, despite being one of the largest and most developed in South Asia, remains under the strict control of powerful military establishment and government, while seeming to mirror the overarching government sentiment with a distinct lack of research-based news. Challenging this state of …
A Relational Approach to How Media Engage With Their Audiences in Social Media
2022
People are increasingly turning to social media for their news and for sharing and discussing news with others. Simultaneously, media organizations are becoming platform-dependent and posting short forms of their news on their social media sites in the hope that audiences will not only consume this news but also comment on and share it. This article joins other media and journalism studies exploring this phenomenon through a relational approach to media audiences to better understand how media organizations, particularly newspapers, are cultivating relationships with audiences via social media. Drawing on public relations theory about organization–public relationships, the article examines …
Editorial: New Forms of Media Work and Its Organizational and Institutional Conditions
2022
This thematic issue explores the widening scope of media work and the institutional and organizational conditions that support new forms of media work. The media industry has undergone significant economic, structural, and technological changes during the past few decades, including changing patterns of ownership and digitalization of media production, distribution, and consumption. Simultaneously, practices of media work are adopted also in other industries. The 10 articles in the issue not only focus on the new professional roles and responsibilities emerging in the news media industry but also study the practices of media work in organizations in other fields, such as the music industry …
