[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

[Bfys-physics] Last two postdoc seminars tomorrow: friday
by Marcel Merk 10 Mar '11

10 Mar '11

Dear friends, Tomorrow (friday) we will have the (for now) last two candidates for a postdoc position visiting us and giving a seminar. The first is Manuel Schiller at 10h30 in N328: "Track reconstruction and towards first LHCb results" Abstract: In his seminar Manuel will discuss trackfinding pattern recognition studies, the K_s analysis and work on the proper time resolution in B_s ---> D_s(K K pi) pi in 2009. The second is Chris Thomas at 14h30 in H220: The title of my talk will be "Measurements of gamma using B->DK and the key role of charm physics inputs". The abstract is: "The CKM angle gamma is currently the least constrained of the angles of the b-d unitarity triangle. Analysis of B->DK decays is a very promising method to determine gamma more precisely. In this talk I present the current status of such analyses, including the prospects for a measurement of gamma at LHCb. I also outline the importance of external inputs from charm physics, in particular focusing on the measurement of the (D0,D0bar)->KShh strong phase difference at CLEO-c." I realise that we had an intensive program with many talks and meetings, but your presence is highly appreciated at these seminars. So I hope to see you all there, best regards, - Marcel

[Bfys-physics] Fwd: Seminar Plamen Hopchev - mistake in time!
by Marcel Merk 10 Mar '11

10 Mar '11

My apologies: the seminar is at 10h30, not at 11h00 !! ---------- Forwarded message ---------- From: Marcel Merk <marcel.merk(a)nikhef.nl> Date: 10 March 2011 09:42 Subject: Seminar Plamen Hopchev To: bfys-physics(a)nikhef.nl, SiimTolk(a)gmail.com Dear friends, Today, Plamen Hopchev is visiting Nikhef for a postdoc application. He will give a 30' seminar at 11h00 in H220 (note location!) on the following topic: "The beam-gas method for absolute luminosity determination" ABSTRACT: "The high resolution of the LHCb vertex detector allows precise measurement of vertices of beam-gas and beam-beam interactions and the determination of beam parameters such as positions, angles and widths. Using the directly measured beam properties a novel method for absolute luminosity normalization has been applied for a first time at the LHCb experiment. The principle requirements and results of the beam-gas luminosity normalization procedure will be described." Hope to see you all there, - Marcel
