• #### ATLAS Detector Monitoring with Jets ﻿

(The University of Bergen, 2009-10-02)
The purpose of this thesis was to provide a high level software framework for detecting large problems with the ATLAS detector at the LHC and estimate the jet resolution from the f irst data. The result was the program ...

• #### Azimuthally differential pion femtoscopy relative to the second and thrid harmonic in Pb-Pb 2.76 TeV collisions from ALICE ﻿

(Elsevier, 2017-11)
Azimuthally differential femtoscopic measurements, being sensitive to spatio-temporal characteristics of the source as well as to the collective velocity fields at freeze-out, provide very important information on the ...
Journal article
• #### Beauty production in pp collisions at √s=2.76 TeV measured via semi-electronic decays ﻿

(Elsevier, 2014-11)
The ALICE Collaboration at the LHC reports measurement of the inclusive production cross section of electrons from semi-leptonic decays of beauty hadrons with rapidity |y|<0.8 and transverse momentum 1<pT<10 GeV/c, in pp ...
Journal article
• #### Centrality dependence of the pseudorapidity density distribution for charged particles in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV ﻿

(Elsevier, 2013-11)
We present the first wide-range measurement of the charged-particle pseudorapidity density distribution, for different centralities (the 0-5%, 5-10%, 10-20%, and 20-30% most central events) in Pb-Pb collisions at $\sqrt{s_{NN}}$ ...
Journal article
• #### Charged-particle multiplicities in $pp$ interactions at $\sqrt{s}$ = 900 GeV measured with the ATLAS detector at the LHC ﻿

(Elsevier, 2010-04)
The first measurements from proton-proton collisions recorded with the ATLAS detector at the LHC are presented. Data were collected in December 2009 using a minimum-bias trigger during collisions at a centre-of-mass energy ...
Journal article
• #### Elliptic flow of muons from heavy-flavour hadron decays at forward rapidity in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV ﻿

(Elsevier, 2016-02)
The elliptic flow, $v_{2}$, of muons from heavy-flavour hadron decays at forward rapidity ($2.5 < y < 4$) is measured in Pb--Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV with the ALICE detector at the LHC. The scalar ...
Journal article
• #### The Higgs Boson in Less Constrained Supersymmetric Models ﻿

(The University of Bergen, 2012-06-01)
In this thesis, we explore the phenomenological minimal supersymmetric standard model (pMSSM) in the context of the Higgs boson. If the emerging results from the LHC are real, will the pMSSM be able to accommodate this? ...
Master thesis
• #### The Higgs-like boson spin from the center–edge asymmetry in the diphoton channel at the LHC ﻿

(Springer, 2015-05-07)
We discuss the discrimination of the 125 GeV spin-parity 0+ Higgs-like boson observed at the LHC, decaying into two photons, H→γγ, against the hypothesis of a minimally coupled JP=2+ narrow diphoton resonance with the same ...
Journal article
• #### Investigations of anisotropic collectivity using multi-particle correlations in pp, p-Pb and Pb-Pb collisions ﻿

(Elsevier, 2017-11)
Two- and multi-particle azimuthal correlations have proven to be an excellent tool to probe the properties of the strongly interacting matter created in heavy-ion collisions. Recently, the results obtained for multi-particle ...
Journal article
• #### Measurement of electrons from beauty hadron decays in pp collisions at root √s=7 TeV ﻿

(Elsevier, 2013-04-10)
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 ...
