Global Determination of $∣ V_{u s} ∣$

Matthew Kirk, Danny van Dyk

In light of ongoing issues with the first-row unitarity test of the CKM matrix, we showcase a global fit to measurements of $K \to ℓ ν$ , $K \to π ℓ ν$ , $τ \to K ν$ , and $τ \to K π ν$ …

Collider-Flavour Complementarity from the bottom to the top

Oliver Atkinson, Christoph Englert, Matthew Kirk +1

Motivated by recently observed anomalies in the flavour sector, we analyse the potential of measurements of top quarks at the Large Hadron Collider (LHC) to provide complementary c…

A Simple Parametrisation of the Pion Form Factor

Matthew Kirk, Bastian Kubis, Méril Reboud +1

We discuss a novel and simple parametrisation of the pion vector form factor that transparently connects spacelike and timelike regions of the momentum transfer $q^{2}$ . Our parametr…
