New paper! Together with Arnau Bas i Beneito and Svjetlana Fajfer we study baryon number violating mixing of a Lambda baryon with its antiparticle. We show that indirect constraints on Lambda-antiLambda oscillations preclude its observation at colliders. 🧪

A cool car that I saw in Germany. You can park everywhere - and if there is no parking spot available, you just put it in your backpack!

Some say that one should not read the papers when cleaning your room. If I did not, I would have thrown out that paper that the great John Bahcall sent to me back in 2000 when I was a postdoc at Cornell… 🧪

New paper! Together with my postdoc Girish Kumar and my graduate student Sudheer Muhammad (first paper!) we look at the effects of the finite widths of the final state particles on the analyses of non-leptonic D meson decays. We welcome your comments!
