I'm Peter Ballett and I work as a researcher in Particle Physics at Durham University.
My research interests broadly lie in particle physics phenomenology and neutrino physics, with connections to flavour physics and model building. I have a particular interest in the phenomenology of neutrino oscillation experiments and their potential for exploring the lepton sector of the SM and beyond (especially anything related to CP violation, leptonic flavour or neutrino mass mechanisms). However, I find that I am interested in most topics in the neutrino sector, adjacent areas and beyond; so please get in touch if you want to discuss anything!
Teaching
For the 2015/2016 academic year, I will be giving lectures on Quantum Electrodynamics for those studying for an MSc in Particle Theory and on Quantum Theory as part of the third year undergraduate Theoretical Physics 3 module.
Research
I have worked on a number of projects related to neutrino oscillation physics, flavour symmetries in the leptonic sector, and the intersection of these two things. Recently, I studied the correlations which can arise from residual symmetries of the group A5 in the presence of a generalised form of CP invariance:
arXiv:1503.07543
I have also studied more general classes of correlations between mixing parameters (socalled 'sum rules') which can be derived under quite general settings in models of discrete symmetries. These offer a nice way to test (a large chunk of) the paradigm of discrete flavour symmetries at upcoming experiments:

arXiv:1308.4313
Around 2013, I worked as a member of the LAGUNALBNO collaboration. I was part of the Physics Task Force which developed and ran the simulations studying the longbaseline physics potential of the design. This work was then built on the following year to perform an analysis of an optimised design, as well as the potential of a dualbaseline facility:
arXiv:1312.6520
arXiv:1412.0593
arXiv:1412.0804
I have also worked on the optimisation of design of the LowEnergy Neutrino Factory, a variant of the standard Neutrino Factory ideal for larger values of theta13:
