Theoretical investigations for testing the fundamental symmetries of the Standard Model with diatomic molecules

To summarize, the present PhD thesis focuses on the theoretical investigations for testing the fundamental symmetries of the Standard Model (SM) with diatomic molecules. Although the SM has great success in describing the fundamental particles and their interactions, it cannot answer many open questions and thus is considered as an incomplete theory. Theoretical investigations of molecular properties have great potential to provide new insights on the questions that cannot be answered by the SM and thus open a window to new physics beyond the SM. We analyze the factors that determine the accuracy of the theoretical investigations and demonstrate the evaluation of theoretical uncertainties. We summarize the main topics of the present work, including the measurement of the nuclear anapole moment effect and electron electric dipole moment (eEDM), and the search for the variation of fundamental constants. We address that the main purpose of this work is to provide the needed molecular parameters for successful measurements of various constants and for rigorous interpretations of the measurements, with the help of the state-of-the-art computational methods. Finally, we present the conclusion for the present work and give an outlook for future work.
