R. Verkade, MSc.

I am a PhD candidate in Theoretical flavour physics in the group of Gravitational Waves and Fundamental Physics (GWFP). I work primarily with Prof.dr. Keri K. Vos on b-quark physics.  I am especially interested in the determination of the Vcb CKM matrix element through semi-leptonic decays of the B meson. The long standing tension between exclusive and inclusive determinations of the Vcb CKM matrix element is my main concern. I specifically focus on the theoretical framework used in inclusive decays, among which, the Heavy Quark Expansion (HQE). Understanding the theory inputs and its limitations is vital for not only an accurate determination but also for making a realistic estimation of the precision.
