A search is presented for direct chargino production based on a disappearing-track signature using 20.3 fb(-1) of proton-proton collisions at root s = 8 TeV collected with the ATLAS experiment at the LHC. In anomaly-mediated supersymmetry breaking (AMSB) models, the lightest chargino is nearly mass degenerate with the lightest neutralino and its lifetime is long enough to be detected in the tracki
Searches for both resonant and nonresonant Higgs boson pair production are performed in the hh -> bb tau tau, gamma gamma WW* final states using 20.3 fb(-1) of pp collision data at a center-of-mass energy of 8 TeV recorded with the ATLAS detector at the Large Hadron Collider. No evidence of their production is observed and 95% confidence-level upper limits on the production cross sections are set.
Cambodia is now facing alarming issues concerning occupational safety and health in the construction sector. According to the ILO, in 2009, every day four people in Cambodia were killed due to occupational accidents which this amounted to more than 1500 death of the construction workers. Based on the union leaders in Cambodia, those accidents and illnesses were seen and occurred at the constructio
PET waste is the most visible environmental threat in the Maldives, a Small Island Developing State (SIDS). The thesis aims to propose the deposit refund system as a policy intervention, and evaluates the feasibility of introducing the system in the Maldives. In order to see how other SIDS have implemented the policy, the research uses policy evaluation framework to analyse the implementation mech
Intestinal spirochetes (Brachyspira spp.) are causative agents of intestinal disorders in animals and humans. Phylogenetic analysis of cloned 16S rRNA genes from biopsies of the intestinal mucosa of the colon from two Swedish 60-years old adults without clinical symptoms revealed the presence of intestinal spirochetes. Seventeen clones from two individuals and 11 reference strains were analyzed an
Buildings account for 40% of energy use and about one third of CO2 emissions in the EU. The huge energy saving potentials offered by the building sector has been targeted by a large number of policy instruments. To improve policy intervention in this area, more information on the extent to which the applied policy instruments are supporting the development and dissemination of different types of e
The summary of the present master thesis can be outlined as the following: The international terrorism and the counter-terrorism have been one of the biggest issues and concerns of the international community over the last decades. The international terrorism aims at the very destruction of human rights, democracy and the rule of law. There is no question and the debate that the international terr
The European energy transition entails opportunities to mitigate two of the EU’s most pressing current challenges: climate change and the energy crisis due to the dependency on fossil fuel imports. The EU has committed to limiting global warming to 2°C (preferably 1.5°C), compared to pre-industrial levels. In the context of the European Green Deal, the EU has set the objective to reach climate neu
This Letter presents a search for exotic decays of the Higgs boson to a pair of new (pseudo)scalar particles, H→aa, where the a particle has a mass in the range 20–60 GeV, and where one of the a bosons decays into a pair of photons and the other to a pair of gluons. The search is performed in event samples enhanced in vector-boson fusion Higgs boson production by requiring two jets with large inva
AIM: To investigate the effects of a case management intervention for community-dwelling frail older people, with functional dependency and repeated contacts with the healthcare services, focusing on loneliness, depressive symptoms and life satisfaction.DESIGN: A two-armed, nonblinded, randomised control trial with repeated follow-ups, of N = 153 participants at baseline allocated to an interventi
A search for Higgs-boson pair production in the bbbb final state is carried out with 3.2 fb-1 of proton-proton collision data collected at s=13 TeV with the ATLAS detector. The data are consistent with the estimated background and are used to set upper limits on the production cross section of Higgs-boson pairs times branching ratio to bbbb for both nonresonant and resonant production. In the case
A search with the ATLAS detector is presented for the Standard Model Higgs boson produced by vector-boson fusion and decaying to a pair of bottom quarks, using 20.2 fb−1 of LHC proton-proton collision data at s=8 TeV. The signal is searched for as a resonance in the invariant mass distribution of a pair of jets containing b-hadrons in vector-boson-fusion candidate events. The yield is measured to
Background We previously showed that the BRCA1 variant c.5096G>A p.Arg1699Gln (R1699Q) was associated with an intermediate risk of breast cancer (BC) and ovarian cancer (OC). This study aimed to assess these cancer risks for R1699Q carriers in a larger cohort, including follow-up of previously studied families, to further define cancer risks and to propose adjusted clinical management of female BR
The cross-section for the production of two jets in association with a leptonically decaying Z boson (Zjj) is measured in proton–proton collisions at a centre-of-mass energy of 13 TeV, using data recorded with the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 3.2 fb−1. The electroweak Zjj cross-section is extracted in a fiducial region chosen to enhance
The title of our presentation refers to the collaborative dimensions of the Nordic Network for Music Education in professional development and knowledge development within our research field. This includes networking between senior and junior researchers, supervisors from different institutions, master students, Ph.D. students and the many discussions, challenging previous beliefs, that shape the
