1. 1. Exploring New Physics Through Collider and Gravitational Wave Measurements with Artificial Neural Networks: the Case Study of QCD-like Technicolor

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Ashar Ahmed Kamal; [2023]
   Keywords : Artificial Neural Networks; ANN; Beyond the Standard Model; BSM; parameter space scan; Physics and Astronomy;

   Abstract : With physicists actively exploring Beyond the Standard Model (BSM) theories that may fill in the gaps of the Standard Model (SM), a fundamental question arises: which parameters hold physical significance? In this thesis, we present our initial progress towards the development of a model-independent artificial intelligence framework designed for conducting parameter space scans in BSM scenarios. Our framework incorporates several publicly available high-energy physics packages, namely SPheno, HiggsBounds, HiggsSignals, and CosmoTransitions. READ MORE

3. 2. Phase Transitions in the Two-Higgs-Doublet Model with a Softly-Broken Z2 Symmetry

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Filip Gustavsson; [2023]
   Keywords : Particle Physics; Beyond Standard Model; Two-Higgs Doublet Model; 2HDM; Electroweak Phase Transitions; Strong First-order Phase Transition; Dimensional Reduction; CP-conserving; Softly broken Z2-symmetry; Physics and Astronomy;

   Abstract : The two-Higgs-doublet model (2HDM) is an extension to the Standard Model which adds a second Higgs doublet. This extension provides freedom within the model, in comparison to the Standard Model, which makes it possible to study strong electroweak phase transitions. READ MORE

4. 3. Expansions of neutrino oscillation and decay probabilities in matter

   University essay from KTH/Fysik

   Author : Jesper Grönroos; [2023]
   Keywords : Theoretical physics; Particle physics; Neutrino physics; Neutrino oscillations; Series expansions; Physics beyond the Standard Model; Teoretisk fysik; Partikelfysik; Neutrinofysik; Neutrinooscillationer; Serieutvecklingar; Fysik bortom Standardmodellen;

   Abstract : We consider a simple model for invisible neutrino decay as a sub-leading effect in the standard three-flavor neutrino oscillation framework, and use the Cayley–Hamilton formalism to obtain a full set of neutrino oscillation probabilities in matter. These are given as analytical series expansions in the small parameters α ∼ O(λ^2) and s_13 ∼ O(λ), where λ ≡ 0. READ MORE

5. 4. Flavour Symmetries in SU(5) Grand Unified Theories

   University essay from KTH/Fysik

   Author : Malte Lindestam; [2021]
   Keywords : ;

   Abstract : The current description of physics on the very smallest scales is given by the standard model (SM) of particle physics. It makes many good predictions and is a highly successful theory. There are however phenomena it cannot explain, and it is therefore not a complete theory of particle physics. READ MORE

6. 5. A literature review of FASERν - An emulsion detector for collider neutrinos

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

   Author : Lisa Andersson Loman; [2021]
   Keywords : physics; neutrinos; FASER; Standard Model; Beyond Standard Model; BSM; particles; elementary particles; neutrino cross sections; LHC; FASER nu; particle physics; physics experiment; CERN; long lived particles; Physics and Astronomy;

   Abstract : In 2021, the ForwArd Search ExpeRiment (FASER) will start searching for light and weakly coupled particles 480m from the proton-proton collision point of ATLAS at the Large Hadron Collider (LHC). The FASER main detector will have a sub-detector, FASERν, sensitive to high-energy collider neutrinos of all flavours. READ MORE
