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

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Author : Andreas Stokkeland; [2023]
   Keywords : 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;

   Abstract : 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. 2. Development of an event generator for antihyperon-hyperon pair production in antiproton-proton collisions

   University essay from Uppsala universitet/Kärnfysik

   Author : Vitor Jose Shen; [2022]
   Keywords : MC event generator; Antihyperon-hyperon pair; Antiproton-proton collisions; PANDA; ROOT; 4-vector kinematics; Angular distribution;

   Abstract : The goal of this project was to develop a lightweight Monte-Carlo (MC) event generator for hyperon pair production in antiproton-proton collisions, and demonstrate it in one of the hyperon decay reaction channels, which is collisions of proton and antiproton to lambda hyperon and anti-lambda hyperon, and they decay to antiproton-positive pion pair, and proton-negative pion pair. The prototype of this external MC event generator we presented here is based on the software framework of ROOT. READ MORE

4. 3. Constraining Physics Beyond the Standard Model with Emerging Jets using the ATLAS Experiment

   University essay from KTH/Fysik

   Author : Simon Thor; [2022]
   Keywords : ATLAS; CERN; particle physics; simulation; Python; C ; standard model; emerging jets; long-lived particles;

   Abstract : Dark matter, the unknown matter that constitutes 85% of all matter in the universe, is one of the greatest mysteries in fundamental physics. One theory that might explain dark matter predicts that there are long-lived particles known as dark pions. READ MORE

5. 4. Quantum Computing in Nuclear Physics

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Luca Bernecker; [2022]
   Keywords : quantum computing; nuclear physics; qubits; theoretical physics; Physics and Astronomy;

   Abstract : In this thesis, we investigate many–body systems using simulations of quan- tum computers. Quantum computing is a computational paradigm based on qubits which are defined in a Hilbert space instead of the familiar binary bits. READ MORE

6. 5. Fitting the pion and kaon mass and decay constant to lattice data

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Hector Tiblom; [2021]
   Keywords : chiral perturbation theory; lattice QCD; pion mass; kaon mass; decay constant; low-energy QCD; Physics and Astronomy;

   Abstract : We use lattice QCD data to perform a fit of the pion and kaon mass and decay constant to next-to-next-to-leading order (NNLO) in three-flavor Chiral Perturbation Theory (ChPT). To improve our fits, we make use of finite volume corrections at both one- and two-loop order. This turns out to provide a small but noticeable improvement of our fits. READ MORE
