1. 6. Transverse Momentum Spectra in pp collisions (\sqrt{s}\) = 7 TeV and \(\sqrt{s}\) = 13 TeV in ALICE

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Författare :Andreas Stokkeland; [2023]
   Nyckelord :Multiplicity; Multiplicity classes; Soft interactions; Quark Gluon Plasma; QGP; transverse momentum; p_T; Chi-squared; fits; fit functions; Levy; Lévy; Exponential; BGBW; Boltzmann-Gibbs blast-wave; Fermi-Dirac; Bose-Einstein; Boltzmann; pion; kaon; proton; transverse momentum spectra; p_T spectra; surface velocity; Minimum Bias; MB; Physics and Astronomy;

   Sammanfattning : In this project particle production as a function of transverse momentum (\(p_{\rm T}\)) in proton-proton collisions at a center-of-mass energy (\(\sqrt{s}\)) of 7 TeV and 13 TeV has been studied. The transverse momentum is interesting to study since it reflects momentum created in the collision (before the collision, all momentum is in the beam - going in a longitudinal direction) and therefore gives information on the collision dynamics.

3. 7. Development of a model for ionospheric instabilities in the equatorial region

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Thea Lepage; [2023]
   Nyckelord :;

   Sammanfattning : This work is part of a bigger project on analyzing the ionospheric dynamics in the equatorial region using simulations. The main objective of this study is to determine and characterize the parameters needed to trigger instabilities and thus the formation of plasma bubbles. LÄS MER

4. 8. Orientation of plasma jet fronts in the Earth's magnetotail

   Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Författare :Atlas Silverhult; [2023]
   Nyckelord :Space physics; plamsa; reconnection; magnetospheric multiscale; MMS; magnetosphere; minimum variance analysis; MVA;

   Sammanfattning : This project aims to investigate the orientation of plasma jet fronts in Earth's magnetotail using multi-spacecraft measurement data. The orientations are estimated by applying minimum variance analysis (MVA) and multi-spacecraft timing analysis for finding normal vectors to the jet fronts as they pass over the spacecraft. LÄS MER

5. 9. Probing Strangeness Production in Proton-Proton Collisions with Three-Particle Correlations

   Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Melinda Petricean; [2023]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : Strangeness production in small systems such as proton-proton collisions is here investigated through the use of three-particle correlations in the momentum-space coordinates η and ϕ. This method is used in order to investigate possible correlation between conservation of both strangeness and baryon number, such that the particles chosen are Λ¯pK+ and the respective charge conjugates, where Λ is a strange baryon, p¯ balances: the Balance Function and the comparative restriction of relative positions for pairs of particles within given triplets.

7. 10. Possible Bow Shock Current Closure to Earth's High Latitude Ionosphere on Open Field Lines

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Gabriella Nordin; [2023]
   Nyckelord :Space Physics; Bow Shock Current; Field-Aligned Currents; Open Field Lines;

   Sammanfattning : The bow shock is formed due to the abrupt deceleration of the supersonic solar wind in front of the terrestrial magnetic field. The solar wind plasma and the Interplanetary Magnetic Field (IMF) are both compressed across the shock, and according to Ampère's law a current thus flows on the bow shock at all times. LÄS MER
