  1. 1. Explaining B-> D^(*) tau nu Decays with a Two Higgs Doublet Model using the Froggatt-Nielsen Framework

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

    Author : Emil Andersson; [2017]
    Keywords : Two Higgs Doublet Model; 2HDM; Froggatt-Nielsen; Flavon; B-meson; Higgs; Beyond Standard Model; BSM; Theoretical Particle Physics; Physics and Astronomy;

    Abstract : In recent years, the BaBar, Belle and LHCb experiments have observed an excess of $B\to D^{(*)}\tau\nu$ decays compared to Standard Model predictions. In this thesis, we investigate if it is possible to explain this excess with a two Higgs doublet model using the Froggatt-Nielsen framework. READ MORE

  3. 2. RGE properties of 2HDM in relation to data on B->Dtu

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

    Author : Joel Oredsson; [2014]
    Keywords : particle physics; high energy physics; B meson; two Higgs doublet model; 2HDM; Higgs; RGE; BSM; Physics and Astronomy;

    Abstract : In this thesis we investigate the properties of a specific two Higgs Doublet Model (2HDM) that can be used to explain the data on B->Dtu and B->D*tu, which deviate from the Standard Model (SM) by 3.4 sigma. The 2HDM is the simplest extension of the Standard model scalar sector. READ MORE

  4. 3. Charm and bottom production at particle colliders

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

    Author : Fabricio Jimenez; [2014]
    Keywords : High Energy Physics. Collider Physics. Monte Carlo Event Generators. Pythia. Heavy flavours.; Physics and Astronomy;

    Abstract : High energy particle collisions involve complex physics, beyond analytical control. Instead, Monte Carlo event generators like Pythia have been used to simulate particle collisions since decades. A study of the production of heavy quarks (namely, charm and bottom) is presented for two different scenarios: lepton (e+e−) and hadron (pp) collisions. READ MORE
