Multiscale simulations of liquid-liquid interfaces: From lipid membrane to graphene
(2023-11-06)There is an increasing demand to enhance the development of coarse-grained models in order to facilitate highly efficient simulations of realistic biological systems. In our endeavor to tackle this challenge, in chapter ... -
Improving Monte Carlo simulations in high energy physics using machine learning techniques
(2023-09-15)Monte Carlo event generators are nowadays indispensable tools for predictions based on first principles in high energy physics, and they represent one of the mainstays of particle physics research at the Large Hadron ... -
Predictions to all orders in perturbative quantum chromodynamics for high energy collider experiments
(2021-11-25)This thesis discusses an implementation of automated all orders calculations in pertur- bative quantum chromodynamics and its application to measurements at recent collider experiments. It is realised as a plugin to the ... -
Direct measurement of the top-quark decay width with the ATLAS detector
(2019-07-10)The top quark is the heaviest known elementary particle. Due to its large mass, the top quark decays before it forms bound states. This makes the top quark a unique particle in the Standard Model. Precise measurements of ... -
Measurement of the Higgs boson production in the H → ττ → τlepτhad decay channel at √s = 13 TeV with the ATLAS detector at the LHC
(2019-06-14)This thesis presents a measurement of the Standard Model Higgs boson production in the H → ττ decay with particular emphasis on the final state in which one tau decays hadronically and the other one decays leptonically, ... -
Fluctuational electrodynamics for nonlinear materials in and out of equilibrium
(2019-05-16)Fluctuational electrodynamics (FE) is a successful and well established theory. By making use of the fluctuation dissipation-theorem (FDT), it ties together the linear response (Green's function) and the strength of thermal ... -
Refining the chemical and kinetic decoupling description of thermally produced dark matter
(2019-03-26)The first part of this thesis deals with refined theoretical predictions of the thermal relic abundance for weakly interacting massive particles (WIMPs). Methods are developed in a model independent way to describe the ... -
Phenomenology at a future 100 TeV hadron collider
(2018-03-13)Run 1 of the Large Hadron Collider (LHC) has been one of the most successful experiments in particle physics. We are now approaching the end of LHC Run 2, and whether we will discover new physics or not, the high ... -
Measurement of the ttZ Production Cross Section in the Final State with Three Charged Leptons using 36.1 fb^-1 of pp Collisions at 13 TeV at the ATLAS Detector
(2018-02-14)A measurement of the production cross section for a top quark pair in association with a Z boson (ttZ) is presented in this PhD thesis. Final states with exactly three charged leptons (electrons or muons) are used, taking ... -
Decaying Dark Matter models at colliders
(2016-04-07)After the first run of LHC, no signal of new physics has been found in terms of the DM motivated channels containing missing energy. Even though the next LHC run could still detect a WIMP-like signal, especially from the ... -
Measurement of the Top Quark Pair Production Cross Section and Simultaneous Extraction of the W Heavy Flavor Fraction at √s = 7 TeV with the ATLAS Detector at the LHC
(2012-04-27)The top quark pair production cross section, σtt, is measured in the semileptonic channel in two datasets using a binned profiled likelihood template fit to data to discriminate the signal, tt, from its main background, ...
