2. The decay of beauty quark to τ lepton and neutrino in the DELPHI experiment at LEP
Sammanfattning : Using 3.5 millions hadronic Z0 events collected during the LEP1 period at the DELPHI detector, the decays of b quarks to tvt have been searched for in both the inclusive and exclusive decay modes. The analysis technique is based on b-tagging, missing energy and identifications of t products. LÄS MER
3. A study of mu-mu- and e-mu-pairs produced in 450 GeV/c p-Be--collisions in HELIOS, and software development for DELPHI
Sammanfattning : The main part of this thesis treats measurements in the HELIOS experiment of the production of e-mu and mu+mu-pairs in 450 GeV/c p-Be collisions. The mumu measurement covers the kinematical covers the kinematical range of 2Mmu < M < 1.5 GeV, 0.03 < xF < 0. LÄS MER
4. Search for Charged Higgs Bosons in e+e− Collisions
Sammanfattning : Several extensions to the Standard Model predict the existence of charged Higgs bosons. This thesis describes the search for such a particle using the data collected by the DELPHI detector at the Large Electron Positron (LEP) collider at the European laboratory for particle physics (CERN) in Geneva, Switzerland.

5. Search for a new light boson in meson decays
Sammanfattning : The subject of the presented work lies in the field of experimental particle physics. The main topic is the study of e+ e− pairs from η meson decays. The data sample used in this work was collected by the WASA-at-COSY collaboration in proton-proton collisions at 1.4 GeV kinetic beam energy. LÄS MER
