1. Impact of loosening the requirement on missing transverse momentum in tt+DMsearches with the ATLAS experiment
University essay from Stockholms universitet/FysikumAbstract : Dark matter is required in the universe to explain certain phenomenona, like the dynamics of stars and temperature fluctuations of the cosmic microwave background. This thesis focuses on the production of dark matter in the ATLAS experiment at the Large Hadron Collider, where the dark matter is detected through momentum conservation. READ MORE

2. Finite temperature effects on decay rates in the real-time formalism
University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationAbstract : This thesis work presents thermal decay rates for several reactions calculated within the framework of the real-time formalism. Processes considered are those of a neutral (pseudo)scalar decaying into two distinct (pseudo)scalars or into a fermion-antifermion pair. READ MORE

3. Exploring selections across channels in Dark Matter searches with top quarks at the ATLAS experiment of the LHC
University essay from Uppsala universitet/HögenergifysikAbstract : Current estimates put Dark Matter to 26% of the energy-matter content of the universe, but very little is known about it other than its gravitational interactions. Eorts to learn more about Dark Matter include searching for it at high energy particle colliders. READ MORE

4. Is it possible to detect the η' → e+e- decay? : A simulation of the η' decay from e+e- collisions
University essay from Uppsala universitet/KärnfysikAbstract : Decays of light, pseudoscalar mesons into lepton pairs are one possible way of detecting physics beyond the Standard Model. This thesis will focus on the η' → e+e- decay, because only few experiments have studied this decay. READ MORE
