Hi Suvayu,
Your talk is great, Suvayu. Below just some suggestions you might consider.
Slide 2. I wanted to tell you already before. You shortly explain that you can have mass eigenstates and weak eigenstates. Very good, but this went relatively fast in your practice talk, while it is the fundament of the CKM matrix and gamma: basically the whole talk. My suggestion: chose your wording carefully here and go very slow! Basically it means that we have two definitions of "what is a quark". If you ask the free Hamiltonian we get different eigenstate that if we ask the weak iteraction Hamiltonian. Molecular physicists e.g. can relate to such issue from different phenomena, but they should first realize how it is related. You basically said this, but superfast. This is a long comment only to ask you to go slow on the first two bullets of slide 2.
Slide 2. Maybe you can say that we also mention beta and beta_s to get full understanding of the CKM, but that you focus on the least known parameter.
Slide 3. I would maximize the size of the figure (actually everywhere in your talk). Now the audience cannot see the fonts in the figure. (I realize it is not very relevant, but the audience always likes to be able to see everthing.)
Slide 4. With the arrows: is it possible to chose delta a bit larger? Now it is not obvious to see that the two blue arrows have not equal length.
Slide 6. Please make the figure a bit larger. The top 4 plots are very small for somebody sitting in the back of the audience. In case you are interested I also have an example to illustrate the B-Bbar oscillations. I attach it in pptx format. Just have a look if you can grab something from it, or not.
Slide 7. Here your audience wil be challenged. Beward that it is difficult. I would only explain the ADS case saying that there are two equally strong decay paths that interfere. As you might know, I always make the reference to Feynman's double slit experiment to explain the interference.
Slide 8. Well explained. I would again enlarge the figures, thinking of the people in the back.
All in all, these are just details. Enjoy your talk and good luck! - Marcel

Hi Everyone,
I have put my latest version of the slides here: https://www.nikhef.nl/~sali/gamma_veldhoven_suvayu.pdf
Indico did not allow me to update the slides on the agenda.
I hope I did not miss any of the comments.
Cheers,
