  1. 1. Constraints on the Kaluza-Klein Photon as a Dark Matter Candidate from the IceCube Collaboration Results

    University essay from Uppsala universitet/Högenergifysik

    Author : Miquel Colom i Bernadich; [2019]
    Keywords : dark matter; WIMP; Kaluza-Klein; IceCube; neutrinos; muon neutrinos; muons;

    Abstract : New constraints on the scattering cross sections of the Kaluza Klein photon as a darkmatter candidate, its annihilation rate in the Sun and the resulting muon flux on Earth are derived.For this purpose, data collected in the IceCube Neutrino Observatory during 532 days of exposurein the austral winters between 2011 and 2014 have been analyzed with Poisson confidence intervals (J.

  2. 2. Supergravity and Kaluza-Klein dimensional reductions

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Roberto Goranci; [2015]
    Keywords : ;

    Abstract : This is a 15 credit project in basic supergravity. We start with the supersymmetry algebra to formulate the relation between fermions and bosons. This project also contains Kaluza-Klein dimensional reduction on a circle. READ MORE

  3. 3. Tagging of Boosted Top Quarks using Reclustered Jets

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

    Author : Jakob Calvén; [2014]
    Keywords : High Energy Particle Physics; Jet Algorithms; Experimental Particle Physics; Boosted Top Quarks; Physics and Astronomy;

    Abstract : The ability to identify boosted top quarks will be of great importance in searches for new physics at the LHC, as boosted tops play an important role in many scenarios of physics beyond the Standard Model. One top tagging algorithm that has been successfully used in the ATLAS collaboration is the HEPTopTagger, which exploits the clustering history of Cambridge/Aachen (C/A) jets to filter out everything but the core objects inside the jets in an attempt to identify those originating from top quark decay.

  4. 4. Gravitational Law in Extra Dimensions

    University essay from KTH/Teoretisk fysik

    Author : Michael Bühlmann; [2013]
    Keywords : ;

    Abstract : Some recent theories which try to amend shortcomings of current models in physics suggest the existence of additional dimensions. Such extra dimensions would modify the inverse square law of gravity. READ MORE

  5. 5. Warped Extra Dimensions in the Randall-Sundrum Model and a Simple Implementation in Pythia 8

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

    Author : Jakob Calvén; [2012]
    Keywords : particle physics; phenomenology; extra dimensions; Physics and Astronomy;

    Abstract : We explore the theory and phenomenology of spatial extra dimensions in the Randall-Sundrum scenario; a possible extension to the Standard Model. We motivate the need for beyond standard model extensions and show how the original Randall- Sundrum model solves the hierarchy problem of particle physics. READ MORE
