Exploration of jet substructure using iterative declustering in pp and Pb–Pb collisions at LHC energies
(Journal article; Peer reviewed, 2020)The ALICE collaboration at the CERN LHC reports novel measurements of jet substructure in pp collisions at √s = 7 TeV and central Pb–Pb collisions at √sNN = 2.76 TeV. Jet substructure of track-based jets is explored via ... -
Exploring Geospace Dynamics Through Ground Magnetic Perturbations during Substorms
(Doctoral thesis, 2024-06-18)Dynamikken på dagsiden av ionosfæren styres hovedsakelig av samspillet mellom det interplanetære magnetfeltet (IMF) og jordens magnetfelt på dagsiden av magnetopausen, mens dynamikken på nattsiden hovedsakelig drives av ... -
Exploring jet profiles in Pb-Pb collisions at 5.02 TeV with the ALICE detector
(Peer reviewed; Journal article, 2019)In this contribution, we present measurements of inclusive jet production with the ALICE detector in Pb-Pb collisions at √sNN = 5.02 TeV. Production cross sections of charged particle jets and fully reconstructed jets are ... -
Exploring jet substructures with jet shapes in ALICE
(Peer reviewed; Journal article, 2017-11)The characterization of the jet substructure can give insight into the microscopic nature of the modification induced on high-momentum partons by the Quark-Gluon Plasma that is formed in ultra-relativistic heavy-ion ... -
Exploring solar-terrestrial interactions via multiple imaging observers
(Journal article; Peer reviewed, 2021)How does solar wind energy flow through the Earth’s magnetosphere, how is it converted and distributed? is the question we want to address. We need to understand how geomagnetic storms and substorms start and grow, not ... -
Exploring the CP-violating Inert-Doublet Model
(Peer reviewed; Journal article, 2011-06-01)We have explored properties of an extension of the Inert Doublet Model by the addition of an extra non-inert scalar doublet. The model offers a possibility of CP violation in the scalar sector and a candidate for the Dark ... -
Exploring the Phase Space of Jet Splittings at ALICE using Grooming and Recursive Techniques
(Peer reviewed; Journal article, 2019)Hard splittings in the evolution of a hard scattered parton may be modified by the presence of a dense strongly interacting medium. Grooming procedures can be used to isolate such hard components of a jet and allows one ... -
Exploring the Predictability of the High-Energy Tail of MEE Precipitation Based on Solar Wind Properties
(Journal article; Peer reviewed, 2023)Medium Energy Electron (MEE) precipitation (≳30 keV) ionizes the mesosphere and initiates chemical reactions, which ultimately can reduce mesospheric and stratospheric ozone. Currently, there are considerable differences ... -
Exploring the use of nanofluids in pump-free systems for solar thermal applications
(Journal article; Peer reviewed, 2023)By using nanofluids as a working fluid in pump-free designs, thermal energy systems can become more efficient and have reduced maintenance costs, ultimately extending the system’s lifespan. In this paper, our goal is to ... -
Exploring virtualisation tools with a new virtualisation provisioning method to test dynamic grid environments for ALICE grid jobs over ARC grid middleware
(Peer reviewed; Journal article, 2014)The Nordic Tier-1 centre for LHC is distributed over several computing centres. It uses ARC as the internal computing grid middleware. ALICE uses its own grid middleware AliEn to distribute jobs and the necessary software ... -
An Extended Scalar Sector: Charged Higgs and Dark Matter
(Doctoral thesis, 2013-10-11)Despite the great success of the Standard Model in describing many aspects of the experiments, there are compelling reasons that it needs to be improved. One of the major mysteries physics has been exploring is the composition ... -
Extended Supersymmetry and Superfields
(Master thesis, 2010-08-01)This thesis concerns the reconstruction of N=1 supersymmetry, starting with the Standard Model. Next, we partially construct an N=2 superfield theory. The differential representation of the N=2 supercharges is found. Issues ... -
Extension of the hard-sphere model for particle-flow simulations
(Journal article; Peer reviewed, 2020)Discrete element methods require appropriate models for particle-particle collisions. Usually, researchers use soft-sphere types of models where the collision dynamics is solved numerically. This makes the simulation ... -
External and Internal Causes of the Stormtime Intensification of the Dawnside Westward Auroral Electrojet
(Journal article; Peer reviewed, 2023)The dawn-dusk asymmetry of magnetic depression is a characteristic feature of the storm main phase. Recently Ohtani (2021, https://doi.org/10.1029/2021JA029643) reported that its magnitude is correlated with the dawnside ... -

Extreme Event Statistics in Dst, SYM-H, and SMR Geomagnetic Indices
(Journal article; Peer reviewed, 2023)Extreme space weather events are rare, and quantifying their likelihood is challenging, often relying on geomagnetic indices obtained from ground-based magnetometer observations that span multiple solar cycles. The Dst ... -
