Dear all,
This is a reminder of the Bfys meeting tomorrow.
The Nikhef agenda page is still the same but can also be found at Nikhef Users -> Kalender intern (indico) -> LHCb -> Bfys Meeting 16 Jan where all Bfys members should be able to login (let's hope so).

Hi Tjeerd,
It took me a bit to follow your guidance, but I found it! It's the new Nikhef indico I realize now: https://indico.nikhef.nl/conferenceDisplay.py?confId=63
However, when I follow the link on that agenda page, she doesn't swallow my credentials? Am I the only one?
Cheers & thanks, Niels

Hi Niels,
I experience the same problem. The link on the agenda page, which says: goto: https://indico.nikhef.nl/conferenceDisplay.py?confId=59 does not work.
Also I cannot modify anything on the first page: https://indico.nikhef.nl/conferenceDisplay.py?confId=63
Anyway, for the Vidyo link, you can still use the old one (given below): https://indico.cern.ch/event/348856/
So the main problem is that the speakers cannot upload any material now.
Cheers Jeroen

We have a group LHCb category and I expect that we all can access to https://indico.nikhef.nl/conferenceDisplay.py?confId=63
If not let me know and I talk to the Indico coordinator.
Best rgards, Tjeerd

Hi Tjeerd,
As far as I can see you did not protect the LHCb category and its events. To be able to view the events one does not need to login into Indico,

Hi Tjeerd,
I can see the agenda, but I cannot modify the agenda. Also, I am not allowed to create a new agenda in the LHCb category. I see that the Managers for the LHCb category are only you and Marcel. I think it would be very useful to add the whole bfys group as managers. At CERN it is possible to give access to a group of people. See for instance the LHCb indico page at CERN:

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,

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

Feynman deserves a lot of credit, for a great many things, but in case of the double-slit experiment, I think it is better refer to Young instead. See eg. http://en.wikipedia.org/wiki/Double-slit_experiment

Hi Marcel,

I'll keep this in mind when speaking.
I'm not sure I can do that. The trade-off is clumsier text in the bullets. I would prefer to keep the text as clear as possible.
About the other figures, most of them cannot be enlarged for one reason or another.
I'll try to play around with the numbers. It's kind of a catch 22, either the vector addition is clear, or the difference between the sums.
This is an example of a figure I cannot make larger. Rose suggested this even before the rehearsal talk. Unfortunately it is after a lot of "magic" I managed to get it in this form from two other figures (where they were composed of 4 actual figures each!). Unfortunately this is the best I can do.
I think I'll remove GGSZ altogether, I will only mention it in the γ combination slide (9).
I will try.
Thanks for the comments.
