(Peer reviewed; Journal article, 2019)
Heavy quarks, i.e. charm and beauty, are sensitive probes of the medium produced in high-energy heavy-ion collisions. They are produced in the early stage of the collision, mainly in hard partonic scattering processes, and ...
• #### Heterogeneous distributed calibration framework for the high level trigger in ALICE ﻿

(Doctoral thesis, 2009-02-13)
This thesis focusses on the development of a distributed and re-configurable online calibration environment for the ALICE (A Large Ion Collider Experiment) HLT (High Level Trigger). ALICE1 is one of the four major experiments ...
• #### Heterogeneous Hydrate Nucleation on Calcite {1014} and Kaolinite {001} Surfaces: A Molecular Dynamics Simulation Study ﻿

(Master thesis, 2016-06-01)
Natural gas hydrates are of significant interest due to the great amount of methane that can potentially be utilised as an energy source. These methane resources are trapped in ice-like form, which is a concern since ...
• #### The Higgs Boson in Less Constrained Supersymmetric Models ﻿

(Master thesis, 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? ...

(Peer reviewed; Journal article, 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 ...

A new phenomenon called terrestrial gamma-ray flashes (TGFs) was discovered early in the 1990s by the NASA satellite Compton Gamma-Ray Observatory. The short-duration bursts of highly energetic gamma-rays are caused by ...
• #### A high-granularity digital tracking calorimeter optimized for proton CT ﻿

(Journal article; Peer reviewed, 2020)
A typical proton CT (pCT) detector comprises a tracking system, used to measure the proton position before and after the imaged object, and an energy/range detector to measure the residual proton range after crossing the ...
• #### High-latitude magnetic fields and their time derivatives: interhemispheric similarities ﻿

(Peer reviewed; Journal article, 2013-02-19)
There are two simple and objective measures of geomagnetic activity: the daily range of field components, and the daily maximum of the time derivative of the field. We study these using data from the geomagnetic latitude ...
