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…

Searches for lepton number violating $K^+$ decays
2019
The NA62 experiment at CERN reports a search for the lepton number violating decays K+ -> pi(-)e(+)e(+) and K+ -> pi(-)mu(+)mu(+) using a data sample collected in 2017. No signals are observed, and upper limits on the branching fractions of these decays of 2.2 x 10(-10) and 4.2 x 10(-11) are obtained, respectively, at 90% confidence level. These upper limits improve on previously reported measurements by factors of 3 and 2, respectively.
Parity violation energy of biomolecules - III: RNA
2006
The energy of parity-violation associated with a typical DNA double helix is estimated with ab initio techniques. It is shown that weak-nuclear interactions do not favor the formation of the double helices found in nature. Possible implications regarding the potential effect of parity-violation interactions on the evolution of biological homochirality are discussed.
Charge-dependent flow and the search for the chiral magnetic wave in Pb-Pb collisions at √sNN = 2.76 TeV
2016
We report on measurements of a charge-dependent flow using a novel three-particle correlator with ALICE in Pb-Pb collisions at the CERN Large Hadron Collider (LHC), and discuss the implications for observation of local parity violation and the chiral magnetic wave (CMW) in heavy-ion collisions. Charge-dependent flow is reported for different collision centralities as a function of the event charge asymmetry. While our results are in qualitative agreement with expectations based on the CMW, the nonzero signal observed in higher harmonics correlations indicates a possible significant background contribution. We also present results on a differential correlator, where the flow of positive and …
Ideological, Institutional and Affective Practices of Interpersonal Violence
2020
The first chapter presents the book’s point of departure as well as its central concepts and structure. It outlines the current understandings of and theoretical approaches to the intersections of violence, gender and affect. The starting point is that gendered violence and violating practices are embedded in social structures of power and in inequalities, institutions, regimes and the symbolic order. They are manifested in human interaction as well as in cultural discourses and representations. The chapter also gives an overview of the abundant research and various perspectives involved in analysing the intersections of violence, gender and affect as well as the continuities and interconne…
Open Dialogue as a Human Rights Aligned Approach
2019
Throughout the last 20 years, the human rights perspective has increasingly developed into a paradigm against which to appraise and evaluate mental health care. This article investigates to what extent the Finnish open dialogue (OD) approach both aligns with human rights and may be qualified to strengthen compliance with human rights perspectives in global mental health care. Being a conceptual paper, the structural and therapeutic principles of OD are theoretically discussed against the background of human rights, as framed by the Universal Declaration of Human Rights, the UN Convention on the Rights of People with Disabilities, and the two recent annual reports of the Human Rights Council…

Effects of Sanctions, Moral Beliefs, and Neutralization on Information Security Policy Violations Across Cultures
2020
A principal concern of organizations is the failure of employees to comply with information security policies (ISPs). Deterrence theory is one of the most frequently used theories for examining ISP violations, yet studies using this theory have produced mixed results. Past research has indicated that cultural differences may be one reason for these inconsistent findings and have hence called for cross-cultural research on deterrence in information security. To address this gap, we formulated a model including deterrence, moral beliefs, shame, and neutralization techniques and tested it with the employees from 48 countries working for a large multinational company. peerReviewed
Phenomenological applications in CP-violating systems in the SM and beyond
2019
El coneixement actual sobre l'estructura de la matèria és el resultat d'un enorme esforç experimental i teòric. El nostre Univers es compon de partícules elementals governades per les quatre forces fonamentals: gravitatòries, febles, electromagnètiques i fortes. El model estàndard (SM) de la física de partícules és la descripció teòrica més senzilla de com es relacionen aquestes partícules i forces, excepte la força gravitatòria. Al llarg dels anys, el SM ha estat capaç d'explicar totes les dades experimentals amb gran precisió, culminant en 2012 amb el descobriment del bosó de Higgs amb una massa de 125 GeV. La seua elegància, simplicitat i alta predictibilitat han convertit el SM en el mi…
