1. 21. Maximum Likelihood Estimation of Hyperon Parameters in Python : Facilitating Novel Studies of Fundamental Symmetries with Modern Software Tools

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Benjamin Verbeek; [2021]
   Keywords : CP-symmetry; maximum log-likelihood; python; estimation; BESIII; PANDA; hyperon; numba;

   Abstract : In this project, an algorithm has been implemented in Python to estimate the parameters describing the production and decay of a spin 1/2 baryon - antibaryon pair. This decay can give clues about a fundamental asymmetry between matter and antimatter. READ MORE

3. 22. Study of Kinematic Variables in Multi-Lepton Final States in search for an Exotic Higgs Boson

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

   Author : Axel Gallén; [2021]
   Keywords : LHC; ATLAS; CERN; Standard Model; Higgs boson; Exotic Higgs boson; Kinematic variables; Physics and Astronomy;

   Abstract : The Large Hadron Collider in Geneva was constructed as a discovery machine. So far, the Higgs boson has been the only discovery at the Large Hadron Collider, but physicists keep on pushing the limit in order to discover new particles. READ MORE

4. 23. Looking for mono-Z signatures in Z-boson and scalar dark matter interactions

   University essay from Uppsala universitet/Högenergifysik

   Author : Magnus Bertilsson; [2021]
   Keywords : Scalar Dark Matter; Z boson; Mono-Z signatures;

   Abstract : Even though there is a multitude of observational evidence from cosmology and astrophysics, the standard model does not include a suitable dark matter candidate and therefore physics beyond the standard model is necessary. There are hypotheses of what the particle candidate could be coming from theories such as supersymmetry or extra dimensions. READ MORE

5. 24. Superradiant axion clouds and their interaction with astrophysical plasma

   University essay from KTH/Fysik

   Author : Erik Engstedt; [2021]
   Keywords : axions; superradiance; black holes; black hole accretion; astrophysical plasma; axioner; strålningsförstärkning; svarta hål; svart hålansamling; astrofysikalisk plasma;

   Abstract : Axions are one of the best-motivated particles beyond the standard model of particle physics and a promising candidate for dark matter. Through the superradiant instability, axions can extract a significant amount of rotational energy from spinning black holes resulting in dense axion clouds. READ MORE

6. 25. Characterisation of Models of New Physics at the LHC

   University essay from Uppsala universitet/Högenergifysik

   Author : Jakub Salko; [2020]
   Keywords : ;

   Abstract : The goal of this thesis is the development and application of model-independent analysis techniques to characterise New Physics states of different kinds from their signatures at the LHC and future colliders. In the first part of the thesis, we outline the general steps from the building of the simplified model and identification of the parameter space to the characterisation potential of the current searches with the focus on the characterisation between different scenarios of Beyond the Standard Model physics.
