• #### R-parity violating chargino decays at the LHC ﻿

(Peer reviewed; Journal article, 2014-12)
Supersymmetric models with R-parity violation (RPV) have become more popular following the lack of any excess of missing energy events at the 8 TeV LHC. To identify such models, the suggested searches generally rely on the ...

(Peer reviewed; Journal article, 2015-06)
We have studied the transverse-momentum $p_{\rm T}$ dependence of the inclusive J/\).psi\) production in p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV, in three center-of-mass rapidity $y_{\rm cms}$ regions, ...
• #### Reaching towards higher masses of supersymmetric particles decaying to tau leptons ﻿

(Master thesis, 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) = ...
• #### Reactive transport modelling of hydrate phase transition dynamics in porous media ﻿

(Doctoral thesis, 2015-03-27)
Gas hydrate is believed to be so abundant in nature that some estimates suggest it contains more than two times equivalent energy of the whole fossil fuels on Earth. Besides, reservoir hydrates have other important aspects ...
• #### Reactive Transport of CO2 in Saline Aquifers with implicit geomechanical analysis ﻿

(Peer reviewed; Journal article, 2009)
Geological storage of CO2 in saline aquifers is a promising way to reduce the concentration of the greenhouse gas in the atmosphere. Injection of CO2 will, however, lead to dissolution of minerals in regions of lowered pH ...
• #### Recalibration of the MEPED Proton Detectors Onboard NOAA POES Satellites ﻿

(Master thesis, 2013-07-04)
In this thesis we have calibrated energetic proton data from the solid state detectors of the MEPED instrument onboard the satellites NOAA 15, 16, 17, 18, and MetOp 02. All these satellites are part of the NOAA/POES program, ...
• #### Reciprocity calibration method for ultrasonic piezoelectric transducers in air ﻿

(Master thesis, 2013-06-17)
The conventional three-transducer reciprocity calibration method for use in gas at ambient pressure and temperature is studied. Modifications are introduced, introducing correction factors for absorption in air, diffraction ...
• #### Reciprocity calibration of ultrasonic piezoelectric disks in air ﻿

(Master thesis, 2015-11-20)
The phase response of a transducer acting as a transmitter or receiver of sound is important in many industrial applications, such as fiscal measurements of natural gas, therein multipath ultrasonic transit-time flow meters, ...
• #### Reconstruction of primary vertices at the ATLAS experiment in Run 1 proton-proton collisions at the LHC ﻿

(Peer reviewed; Journal article, 2017-05)
This paper presents the method and performance of primary vertex reconstruction in proton--proton collision data recorded by the ATLAS experiment during Run 1 of the LHC. The studies presented focus on data taken during ...
• #### Recreating the top quark: Commissioning and monitoring of the ATLAS Inner Detector and search for New Physics with heavy particles. ﻿

(Doctoral thesis, 2012-02-03)
The ATLAS (A Toroidal Lhc ApparatuS) experiment is one of the two general purpose experiments at the Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research. The LHC is a proton-proton and ion-ion ...
