[Bfys-physics] Invitation to my PhD defense
by Chiara Farinelli 19 Sep '14

19 Sep '14

Dear friends and family, After five years of joys and sorrows the end has finally come (almost), and I am happy to invite you to the defense of my PhD thesis on the: *"Performance of the LHCb Vertex Locator and Flavor Tagging Studies for the Measurement of * *the CKM Angle γ"* that will take place on *Thursday September 25th, at 13:45* in the Aula of the VU University (De Boelelaan 1005, Amsterdam). The ceremony will last about one hour, with me giving a short presentation on my work in the first 10 minutes and a shower of questions from the committee for the next 50 minutes :) However it will end, there will be a small reception directly after the defense with some drinks and snacks so, depending on the outcome of the defense, we will either celebrate or try to forget! On the same evening I will then have a party, which I hope that you will all be able to attend (yes, now I am hoping that we will be celebrating)! The exact time and location of the party have not been decided yet, but more information will follow shortly. Last but not least, I will have two 'witnesses' to help me in the period before the defense and to stand by my side during the defense itself. For many of you this will not be a surprise, but I am happy to leave the hard work of paranymphing in the hands of Serena Oggero and Daan van Eijk, whom you can contact in case you have any questions and from whom you will be hearing more in the next two months! Their email addresses are: Serena Oggero *serena.oggero(a)gmail.com <serena.oggero(a)gmail.com>* Daan van Eijk *d.vaneijk.gm(a)gmail.com <d.vaneijk.gm(a)gmail.com>* Hope to see you all on the 25th! Cheers, Chiara

[Bfys-physics] Fwd: First AND ONLY circulation of publication draft for PAPER-2014-049, Observation of the rare $B_s^0 \to \mu^+\mu^-$ decay from the combined analysis of CMS and LHCb data
by Marcel Merk 04 Sep '14

04 Sep '14

Dear bfys friends, Below is a mail announcing the circulation of the Bsmumu paper, which is submitted to Nature. We are not requested to read it as an institute, but I think it would be good if we would review it anyway because of the unique character of the paper (submitted to Nature) and since we have been deeply involved in the work. regards, - Marcel ---------- Forwarded message ---------- From: Rolf Oldeman <rudolf.oldeman(a)cern.ch> Date: 28 August 2014 17:02 Subject: First AND ONLY circulation of publication draft for PAPER-2014-049, Observation of the rare $B_s^0 \to \mu^+\mu^-$ decay from the combined analysis of CMS and LHCb data To: "lhcb-general (LHCb General mailing list)" <lhcb-general(a)cern.ch> Dear Colleagues, This is to announce the first and only 11-day circulation of the paper describing the combined analysis of the Bs->mumu decay from LHCb and CMS data. This draft is coauthored with CMS and went into circulation with the same deadline there today as well.

Dear all, We have a short paper to be commented by Nikhef before Tuesday 19/8. Please, give your comments by email. I will collect them latest on Tuesday and upload our comments, after a short check with you, that evening to CDS.

Although the main body of the draft has been fully reviewed and signed off by the reviewers, a couple of 'technical' items are still missing due the very short available time between approval and the proponent leaving for a trip. The present draft misses: paper number / author list / PRL justification / word count Please send any comments via the CDS system. It is the responsibility of the contact authors to provide replies on all comments made. Subsequent modification to the publication are made in consultation with the reviewers and during the EB reading. Following this, there will be a final meeting of the editorial board with contact authors and reviewers present where final decisions are made.

[Bfys-physics] Tuesday Seminar
by Patrick Koppenburg 12 Aug '14

12 Aug '14

Hi All, For those who may not be on ph-dep-info-seminars (one can actually subscribe to that list, I just noticed). Cheers, Patrick > Dear all, > > > Please find details and poster related to the CERN-LHC Seminar TODAY on Tuesday 12th of August in the Council Chamber (503/1-001) at 11h00: > > “Gamma measurements in Bs->DsK and other tree-level decays” > by Manuel Tobias Schiller (NIKHEF (NL)) > > https://indico.cern.ch/event/325959/ > > > Abstract: The angle gamma is the least constrained parameter in the CKM unitarity triangle. Its determination in decays induced by tree-level b -> u transitions is largely unaffected by potential new physics contributions. > This allows for a consistency check of the unitarity triangle, but also of comparisons with gamma determinations from modes with loop-diagrams. > We present here a new precise determination of gamma using a time-dependent flavour-tagged analysis of Bs -> Ds K decays with the LHCb experiment. > New developments in flavour tagging are presented. > > Please note that a Webcast will be available for this Seminar. > > Kind regards, > Claire
