Samenvatting

Het onderzoek richt zich op de theoretische aspecten van het testen van een van de fundamenten van de hedendaagse (theoretische) natuurkunde: Lorentzsymmetrie. Het belang van deze symmetrie kent zijn oorsprong in de speciale relativiteitstheorie van Einstein, waarvan ze de basis is.

Er zijn minstens twee redenen om Lorentzsymmetrie te testen. Enerzijds is het, vanwege haar diepe geworteldheid in alle natuurkundige theorieën, van belang om Lorentzsymmetrie met steeds grotere experimentele preciezie te blijven bevestigen. Anderzijds heeft onderzoek naar nieuwe fundamentele theorieën de mogelijkheid voor afwijkingen van Lorentzsymmetrie aan het licht gebracht.

Dit laatste heeft ertoe geleid dat de laatste twee decennia veel onderzoek is naar het testen van Lorentzsymmetrie. Met name in de deeltjesfysica is er veel aandacht voor deze kwestie. Voordat het werk dat beschreven staat in dit proefschrift gedaan werd, bleef deze aandacht echter voornamelijk beperkt tot een specifiek deel van de deeltjesfysica, te weten de kwantumelektrodynamica.

In dit proefschrift wordt het testgebied van Lorentzsymmetrie uitgebreid naar een ander belangrijk deel van de deeltjesfysica: de zwakke interactie. Die interactie is van belang voor kernreacties en het voortbestaan van de zon. Wij hebben wiskundige stappen gezet die het mogelijk maken Lorentzsymmetrie ook in de zwakke interactie precies te testen. Vervolgens hebben we aanbevelingen voor nieuwe experimenten gedaan. Ook hebben we met bestaande experimentele data kunnen bevestigen dat ons werk nieuwe en unieke limieten op afwijkingen van Lorentzsymmetrie oplevert. We hebben ook één resultaat gevonden waaruit blijkt dat Lorentzsymmetrie niet volmaakt is, maar dit moet nog verder onderzocht worden.

abstract = "The research focusses on theoretical aspects of testing one of the fundamental parts of contemporary (theoretical) physics: Lorentz symmetry. The significance of this symmetry has its roots in Einstein's theory of special relativity, of which it forms the basis.There are at least two reasons for testing Lorentz symmetry. Firstly, it remains important to experimentally confirm Lorentz symmetry with growing precision because of its deep embedding in all our theories of nature. Secondly, research on new fundamental theories has brought to light the possibility of deviations from Lorentz symmetry.The latter has led to many investigations of Lorentz symmetry over the last two decades. In particular in particle physics the issue has gained much attention. Previous to the work described in this thesis, this attention was mainly limited to a specific part of particle physics: quantum electrodynamics.In the thesis the testing grounds for Lorentz symmetry are extended to a different important part of particle physics: the weak interaction. This interaction is relevant in nuclear reactions and for the existence of the Sun. We took mathematical steps that enable the testing of Lorentz symmetry also in the weak interaction. Subsequently we made recommendations for new experiments. In addition we confirmed, using existing experimental data, that our work gives new and unique limits on deviations from Lorentz symmetry. We also found one result that seems to suggest that Lorentz symmetry is not exact, however, this needs to be investigated further.",
