  1. 6. CP Violation Studies in Cascade Decay Sequence

    University essay from Uppsala universitet/Kärnfysik

    Author : Roman Sultanov; [2022]
    Keywords : CP violation; cascade; decay; asymmetry parameters; polarisation; uncertainty;

    Abstract : This thesis studies CP violation in the decay of the Ξ− hyperon, also known as the cascade baryon, which decays in the sequence Ξ− → Λπ− → pπ−π−. A difference between the angular distribution of this decay sequence and the angular distribution of the charge conjugate decay sequence ͞Ξ+ →͞Λπ+ → ͞pπ+π+, after taking into account the inversion of the momenta due to the parity operation, is indicative of CP violation.

  3. 7. Derivation of the angular momentum of primary fission fragments from isomeric yield ratio by TALYS using Python

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Mohammad Bagher Nori; [2021]
    Keywords : Nuclear physics; nuclear fission; angular momentum; fission fragments; isomeric yield ratios; fission products;

    Abstract : The general fission process is well known and is applied in nuclear power plants all over the world. However many properties of fission fragments are still not well understood. READ MORE

  4. 8. Impact of loosening the requirement on missing transverse momentum in tt+DMsearches with the ATLAS experiment

    University essay from Stockholms universitet/Fysikum

    Author : Alice Knutas; [2021]
    Keywords : ;

    Abstract : 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

  5. 9. PHITS simulations for CEvNS experiments at ESS

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

    Author : Jesper Karlsson Gumprecht; [2021]
    Keywords : PHITS; CEvNS; Coherent; ESS; Physics and Astronomy;

    Abstract : Recently the interest for coherent elastic neutrino-nucleus scattering experiments has increased since it is believed that through these experiments, a wide range of new physics, e.g., sterile neutrinos, could be discovered. READ MORE

  6. 10. Simulation of Higgs boson pair production in Vector Boson Fusion at the LHC

    University essay from Uppsala universitet/Högenergifysik

    Author : Daniela Romero; [2021]
    Keywords : Higgs boson; vbf; vector boson fusion; high energy physics; lhc; proton collision; madgraph; simulation;

    Abstract : MadGraph5 is used to generate events with Higgs boson pairs from vector boson fusion (VBF) at leading-order (LO) and next-to-leading-order (NLO) accuracy in QCD. The simulations are used to compute fiducial cross-sections in proton-proton collisions at a centre-of-mass energy of 13 TeV, using several kinematic cuts on the outgoing jets, e.g. READ MORE
