1. 6. Characterisation of the LYCCA Double-Sided Silicon Strip Detectors

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

   Author : Marwan Mohamed; [2023]
   Keywords : DSSD LYCCA HISPEC FAIR Characterisation; Physics and Astronomy;

   Abstract : The goal of this thesis work is to describe the methods used and perform comprehensive testing of the Double-Sided Silicon-Strip Detectors (DSSD) prior to their implementation in the Lund-York-Cologne CAlorimeter (LYCCA) detector. In the framework of this project, the DSSD characterisation was carried out to ensure specification compliance prior to their "in-kind contribution" delivery to the HISPEC experiment at the NUSTAR collaboration.

3. 7. Long-Lived Particles from exotic Higgs decays at the FCC-ee

   University essay from Uppsala universitet/Högenergifysik

   Author : Magdalena Vande Voorde; [2023]
   Keywords : ;

   Abstract : This thesis presents the first sensitivity analysis for exotic Higgs boson decays at the electron-positron stage of the Future Circular Collider (FCC-ee) within the FCCAnalyses framework. The project studies the production of a Higgs boson in association with a Z boson in electron-positron collisions at a center-of-mass energy of 240 GeV, with the Higgs boson decaying into two long-lived scalars and the Z boson decaying leptonically.

4. 8. RF Compressor (SLED) Phase-Modulation to Reduce Peak Fields in the MAX IV Linear Accelerator

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Joel Ekström; [2023]
   Keywords : Accelerator; MAX IV; LINAC; Phase-modulation; SLED; Pulse compression; Technology and Engineering;

   Abstract : Modern particle accelerators need strong electric fields in order to produce high energy particles. Such high voltages are typically reached by injecting pulsed radio frequency power through several steps of amplification. At the end, pulse compression is used to further improve the energy gain at the cost of pulse-length. READ MORE

5. 9. Study of the decay modes of Ξc0→pK−K−π+ with the LHCb experiment.

   University essay from Uppsala universitet/Kärnfysik

   Author : Yuliya Bilinskaya; [2022]
   Keywords : Particle physics; hadron physics; resonance; particle decay; LHCb; Dalitz plot; Lambda resonance; Delta resonance;

   Abstract : This thesis reports the first indications of the Λ(1520) and ∆(1232)++ decay modes in the Ξc0 → pK−K−π+ decay. The obtained fractions relative the inclusive Ξc0 → pK−K−π+ decay are (6.4±0.6)% and (32. READ MORE

6. 10. Spin correlations in top quark pair production at the Large Hadron Collider

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Simon Ahlstedt; [2022]
   Keywords : Top quarks; Top quark pair production; LHC; Spin correlations; MadGraph5_aMC@NLO; Dilepton decay channel; Leading order; Interference effects; Event generation.; Physics and Astronomy;

   Abstract : In this work we investigate the spin correlation effect of the interference between signal and irreducible background events present in top quark pair production at the LHC at LO in the dilepton channel. To simulate the high energy proton-proton collisions of the LHC, MadGraph5_aMC@NLO framework is used as an event generator. READ MORE
