1. Dark Matter signals at the Large Hadron Collider with Deep Learning
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : While holding a firm position in popular culture and science fiction, Dark Matter (DM) is nonetheless a highly relevant topic at the forefront of modern particle physics. We study the applicability of characterizing DM particle candidates SUSY neutralino and sneutrino using Deep Learning (DL) methods. READ MORE

2. Looking for mono-Z signatures in Z-boson and scalar dark matter interactions
University essay from Uppsala universitet/HögenergifysikAbstract : 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

3. Characterization of the Spin of Dark Matter at the LHC
University essay from Uppsala universitet/HögenergifysikAbstract : The potential for characterizing the spin and mass of dark matter at the Large Hadron Collider (LHC) given a 5 sigma confidence level discovery has been studied. The search for dark matter is one of the big open question in particle physics as observations predict 84 percent of the matter in the universe to be dark matter, however no detection has been made.

4. Derivation of a transfer function to estimate the Z(vv)+jets background from photon+jets in a search for dark matter at the ATLAS detector
University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionenAbstract : It has for long been known that dark matter must exist in our universe. Despite massive efforts to detect dark matter, its constituents remain a mystery. One strategy to unveil this mystery is to produce dark matter by colliding Standard Model particles. READ MORE

5. Exotic Decays of a Vector-liketop Partner at the LHC
University essay from Uppsala universitet/HögenergifysikAbstract : An evaluation of how sensitive some ATLAS searches for new physics are to a new beyond standard model (BSM) vector-like quark (VLQ) and a pseudo Nambu-Goldstone boson (pNGB) scalar. This was done by simulating a signal containing these new particles and making a recast of it onto existing verified ATLAS searches for new physics at center-of-mass (CM) energy of 13 TeV (Run 2) at the Large Hadron Collider (LHC).
