1. 11. Exploring the Gauge Sector of a Composite Two-Higgs Doublet Model

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Adam Warnerbring; [2021]
   Keywords : two-Higgs doublet model; composite Higgs model; composite two-Higgs doublet model; Physics and Astronomy;

   Abstract : In this bachelor thesis we investigate the gauge sector of a specific composite two-Higgs doublet model, allowing more freedom for the gauge couplings and compositeness scales. From the underlying parameters we generate model realisations with the correct top mass, Higgs mass and electroweak vacuum expectation value, that satisfy theoretical constraints such as unitarity and perturbativity.

3. 12. Observing stellar streams made in a supercomputer

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Erik Fridén; [2021]
   Keywords : Physics and Astronomy;

   Abstract : Stellar streams are made of stars that originate from globular clusters or dwarf satellite galaxies that have been disturbed by the gravitational pull from the galaxy they orbit. These stellar streams hold information about the history of the progenitor as well as information about the gravitational potential of the host galaxy. READ MORE

4. 13. Evaluation of float-truncation based compression techniques for the ATLAS jet trigger

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

   Author : Love Kildetoft; [2021]
   Keywords : Physics and Astronomy;

   Abstract : Data compression methods allow more data to be stored within a certain storage framework while still keeping the characteristics of the data in question. At the Large Hadron Collider on the grounds of CERN in Switzerland, limited data storage capability is and has always been an urgent problem. READ MORE

5. 14. 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. 15. Searching for Dark Photons with Jet

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Ashar Ahmed Kamal; [2020]
   Keywords : light dark matter; jet substructure; Physics and Astronomy;

   Abstract : Dark matter is the greatest mystery of modern particle physics and cosmology. Although an overwhelming amount of observational cosmological evidence has pointed towards a dark sector, only its gravitational effect has been experimentally confirmed. READ MORE
