3. 2. Assessing Ransomware Mitigation Strategies in Swedish Organizations: A Focus on Phishing Emails

   Kandidat-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Johan Liedgren; Felix von Bonsdorff; [2023]
   Nyckelord :Ransomware; ransomware mitigation; phishing; phishing emails; malware prevention strategies;

   Sammanfattning : Ransomware has been a growing threat to today's organizations, with irreparable damages and billions of dollars lost, it is crucial for organizations to implement mitigation strategies that can counter these attacks. With phishing attempts being the primary attack vector, it is evident that organizations need to implement the best practices in order to avoid the consequences. LÄS MER

4. 3. Studies of the axial-vector transition form factors of the process Ω− → W−Ξ0 in chiral perturbation theory

   Master-uppsats, Uppsala universitet/Kärnfysik

   Författare :Hélène De Munck; [2023]
   Nyckelord :Transition form Factors; Next-to-next-to-leading order; chiral perturbation theory; axial-vector; Ω− → W−Ξ0;

   Sammanfattning : This work is included in a broader research of the hadron theory group of Uppsala University and its collaborators tackling the quest for an understanding of the quark distribution inside hadrons by joining threedifferent approaches of QCD namely chiral perturbation theory, dispersion theory and lattice QCD. This thesis contributes by computing in chiral perturbation theory, the quark-masses dependence of form factors. LÄS MER

5. 4. On the vector transition form factors in the Ω- → Ξ0 W- decay

   Master-uppsats, Uppsala universitet/Kärnfysik

   Författare :Magnus Bertilsson; [2023]
   Nyckelord :QCD; Form factors; Vector form factors; Chiral perturbation theory; One-loop diagrams; Hadrons; Hadron physics; Hyperon decay; Hadron structure;

   Sammanfattning : To learn more about the structure of hadrons we study form factors. In the semi-leptonic decay Ω- → Ξ0W- two types of form factors arise namely the vector and axial-vector transition form factors. LÄS MER
