Reaching towards higher masses of supersymmetric particles decaying to tau leptons
(The University of Bergen, 2014-06-30)
This thesis presents an optimisation of the search for SUSY in final states with one tau lepton, jets and missing transverse energy. The SUSY model considered is mSUGRA with the parameter values: A_0 = -2m0, tan(beta) ...
Measurement of electrons from beauty hadron decays in pp collisions at root √s=7 TeV
The production cross section of electrons from semileptonic decays of beauty hadrons was measured at mid-rapidity (|y| < 0.8) in the transverse momentum range 1 < pT <8 GeV/c with the ALICE experiment at the CERN LHC in ...
Permittivity measurements using dual open ended coaxial probes
(The University of Bergen, 2012-11-19)
The motivation for this study has been to conduct a feasibility study on a measuring device to monitor hydrate formation close to the inner surface of a pipe where a multiphase hydrocarbon fluid mixture is flowing. This ...
Search for dark matter in events with a Z boson and missing transverse momentum in pp collisions at √s = 8TeV with the ATLAS detector
(American Physical Society, 2014-07-10)
A search is presented for production of dark-matter particles recoiling against a leptonically decaying Z boson in 20.3 fb⎻¹ of pp collisions at s√=8 TeV with the ATLAS detector at the Large Hadron Collider. Events with ...
Experimental Investigation of the Impedance Measurement Method for Detecting Dust and Gas Flames in a Flame Acceleration Tube. Development of Experimental Apparatus
(The University of Bergen, 2009-06-02)
This master thesis describes an impedance measurement device built for investigating flame propagation in a Flame Acceleration Tube, FAT. This tube is 3.6 m long, and has been instrumented with thermocouples, pressure ...
Study of heavy-flavor quarks produced in association with top-quark pairs at √s =7 TeV using the ATLAS detector
(American Physical Society, 2014-04-21)
Using a sample of dilepton top-quark pair (tt¯) candidate events, a study is performed of the production of top-quark pairs together with heavy-flavor (HF) quarks, the sum of tt¯+b+X and tt¯+c+X, collectively referred to ...
Search for long-lived neutral particles decaying into lepton jets in proton-proton collisions at √s= 8TeV with the ATLAS detector
Several models of physics beyond the Standard Model predict neutral particles that decay into final states consisting of collimated jets of light leptons and hadrons (so-called “lepton jets”). These particles can also be ...
Photon, neutrino and charged particle spectra from R-violating gravitino decays
We study photonic, neutrino and charged particle signatures from slow decays of gravitino dark matter in supersymmetric theories where R-parity is explicitly broken by trilinear operators. Photons and (anti-)fermions from ...
Experimental study of diffusive oil recovery during low salinity waterflooding and miscible CO2 injection in sandstones and shales
(The University of Bergen, 2014-11-24)
This experimental thesis presents a study of two diffusive EOR techniques; low salinity waterflooding in 2D sandstone silicon wafer micromodels and miscible CO2 injection in tight shale core samples. Tests were conducted ...
