Project Description

The Belle 2 experiment at KEK in Tsukuba, Japan, accumulates data from collisions of electrons and positrons. This results in the creation of entangled pairs of neutral B mesons, as well as pairs of charged B mesons and other final states, like tau leptons pairs.  Entangled neutral B mesons are sub-atomic qbits that can be analysed via their decays to flavour specific eigenstates and CP eigenstates.  These are filter analogues of the spin selectors in a Stern Gerlach experiment that enable fundamental tests of discrete symmetries and quantum mechanics.  This project focuses on using data from Belle 2 to explore these quantum entangled systems.  For students with a good mathematical background who want a combination of particle physics analysis and the opportunity to undertake some phenomenological investigations to guide that analysis, you will have the (optional)  opportunity to explore ideas related to possible new types of measurement that could constitute new ways to search for “new physics” beyond the Standard Model of Particle Physics.  With the recent detector upgrades having been completed at Belle 2 now is an ideal time to join the experiment to perform these measurements. 


You will be supervised by two world leading scientists in the field of heavy flavour physics who run the Belle 2 group at QMUL, and will have the opportunity to complete a service task for authorship qualification on the experiment that will have a broad impact on the scientific output of the whole Belle 2 collaboration.
