  1. 21. The 't Hooft model as a testing ground for Quantum Chromodynamics

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Felix Tellander; [2016]
    Keywords : Physics and Astronomy;

    Abstract : We study a 1+1 dimensional Yang-Mills model in the light-cone gauge (the ’t Hooft model). The colour group is SU (N ) and we study the limit N → ∞, the limit is taken such that g²N is kept constant. In this limit the only contributing diagrams are planar diagrams without gluon-gluon interactions. READ MORE

  3. 22. Monte Carlo simulations of D-mesons with extended targets in the PANDA detector

    University essay from Uppsala universitet/Kärnfysik

    Author : Mattias Gustafsson; [2016]
    Keywords : Monte Carlo simulations; PANDA; reconstruction D-meson; pellet target; cluster-jet target;

    Abstract : Within the PANDA experiment, proton anti-proton collisions will be studied in order to gain knowledge about the strong interaction. One interesting aspect is the production and decay of charmed hadrons. The charm quark is three orders of magnitude heavier than the light up- and down-quarks which constitue the matter we consist of. READ MORE

  4. 23. A supersymmetric, E8 inspired, unification model

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Astrid Ordell; [2016]
    Keywords : Physics and Astronomy;

    Abstract : The thesis treats the construction of a supersymmetric model, inspired by an E8 unfication scenario. Via the introduction of adjoint representation chiral superfields, in combination with the inclusion of a global generation symmetry, the Standard Model fermion candidates are protected from gaining any mass until electroweak symmetry breaking.

  5. 24. Observation of the associated production of a J/psi meson with a W boson in pp collisions at 8 TeV using the ATLAS detector

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

    Author : Rickard Lydahl; [2016]
    Keywords : ATLAS; LHC; J psi meson; Z boson; W boson; particle production; Physics and Astronomy;

    Abstract : In this thesis the observation of the rare associated particle production of a J/psi meson in association with a W boson is reported using 20.3 fb^-1 of data from proton-proton collisions at 8 TeV with the ATLAS detector. READ MORE

  6. 25. Study of Proton Emission in Complex Nuclei

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Jonatan Adolfsson; [2016]
    Keywords : Nuclear physics; Nuclear theory; Nuclei far from stability; Proton decay; Cobalt-53; Physics and Astronomy;

    Abstract : In a recent experiment, the partial half-life ([i]t[/i][sub]1/2[/sub]) of proton emission from the [i]I[/i][sup]π[/sup] = 19/2[sup]-[/sup] state of [sup]53[/sup]Co was accurately measured. A previous estimate is [i]t[/i][sub]1/2[/sub] ~ 17 s. READ MORE
