[Bfys-physics] bfys meeting upgrade
by Marcel Merk 13 May '11

13 May '11

Dear bfys group members, Today we have a bfys discussion on the upgrade plans to present to Nikhef. The nature of the meeting is more about planning and financing. Although OIO's are welcome to join, there is no need if they have other business. Also the meeting is not broadcasted on EVO. My apologies, - Marcel

[Bfys-physics] Beauty conference fee
by Marcel Merk 23 Mar '11

23 Mar '11

Dear group members, This is a message to all group members that registered for beauty and have not yet payed the fee: "It is not needed to pay the fee." The money transfer will be done in one go by Fred Bulten. For those of you that already payed: do nothing. It will be subtracted by Fred. Cheers, - Marcel

[Bfys-physics] Posters at Beauty
by Marcel Merk 22 Mar '11

22 Mar '11

Dear Friends, I hereby would like to remind you that there is a possibility to show posters at the beauty conference in Amsterdam (4-8 April). Students could consider together with their supervisors whether this is a good opportunity to show their analysis to the community. Cheers, - Marcel

Dear colleagues, I just received the following reactions to our comments. If you have a reaction which you want to communicate: - send it to me for collection - or communicate yourself if you wish to enter into a discussion. Best regards, Tjeerd PS Daan, did you keep the original draft. I lost mine.

[Bfys-physics] beauty registration
by Marcel Merk 16 Mar '11

16 Mar '11

Dear collegues, Those of you plan to join to the beauty 2011 conference, please fill in the registration on the beauty 2011 web page. The payment can be skipped for the moment since it would just mean a money flow from Nikhef to Nikhef. We will take care of this later on. best regards, - Marcel

[Bfys-physics] B-physics seminar of Tom Blake
by Marcel Merk 12 Mar '11

12 Mar '11

Dear Friends, This afternoon at 14h30 we have in N328 a seminar of Tom Blake, a postdoc applicant for our group. "Search for New Physics with the Rare Heavy Flavour Decay \BdKsmm" The abstract is: The rare decay \BdKsmm is widely acknowledged to be one of the most promising channels for indirect searches for new physics. Recent results from \babar, Belle and CDF have generated much excitement, where each experiment observes a wrong sign angular symmetry compared to the Standard Model prediction. LHCb's sensitivity to this decay is explored based on our knowledge from the 2010 data taking period. It will be shown that LHCb is in a strong position to make a world leading measurement with the data expected in 2011. Hope to see you there, - Marcel
