• #### 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 ...

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 ...
