[Bfys-physics] Bfys and videogw
by Tjeerd Ketel 21 Feb '14

21 Feb '14

Dear all, Apologies for the problems this morning. I did not check the vidyo in advance. With the new Vidyo version its link: Vidyo link in Nikhef Bfys Meeting (at Institutes->Nikhef of Friday 21 June 2013) https://indico.cern.ch/conferenceDisplay.py?confId=255991 protected by PIN 1328. did not have a link anymore to vidyo (with More info and Join Now). A new meeting was set up that crashed rather quickly, but now it seems to be stable. A way to connect the Polycom to this Nikhef Bfys Meeting is: 1. Select CERN or type Vidyogw.cern.ch 2. Place a call by pressing the telephone button 3. Type room extension (first # to activate the number key) followed by # 93038631 # 4. Type room pin followed by # 1328 # 5. You are in now as participant video2 (in H331) 6. Activate the microphone if on mute (red light on microphone) 7. Check speaker volume on Polycom and on TV screen Hopefully, next Bfys meeting has no vidyo problems. Best regards, Tjeerd

Dear all, I received the reaction on our comments on LHCB-PAPER-2013-067 Tjeerd Without other remarks I propose to answer with ========================================== Dear contact authors, Thank you for your reactions and explanations. >From your answer it seems that our first general comment was not clearly formulated. Let me try it again: - In the abstract is stated "No significant polarisation is observed". - In the conclusion is stated "For lambda_theta the phi(2S) meson does not show large transverse polarization". - In the data (tables and figure 5) a significant negative value of lambda_theta is observed at large pT which is not the polarisation predicted by CSM (larger negative) and by NRQCD (same size positive). But in that pT bin the polarizaton is different from zero. Therefore, the statement in the abstract does not seem to be correct. Maybe it is best to repeat the statement made in the conclusion. ============================ ---------- Forwarded message ---------- Date: Thu, 13 Feb 2014 07:02:38 +0100 From: CERN Document Server Submission Engine <cds.support(a)cern.ch> To: tjeerd(a)nikhef.nl Subject: LHCB-PAPER-2013-067-001-COMMENT-012 (a comment has been made on your comment) Dear LHCb Colleague, The comment (LHCB-PAPER-2013-067-001-COMMENT-004) that you made on LHCB-PAPER-2013-067-001 (entitled: 'Measurement of $\psi(2S)$ polarisation in $pp$ collisions at $\sqrt{s}=7\mathrm{TeV}$') has itself been commented on by Yanxi Zhang [CERN] (yanxi.zhang(a)cern.ch).

Dear colleagues, Bfys Meeting Friday 31 January in H331 and Vidyo 9:15 - 9:40 Staff meeting (only permanent staff) 9:45 - 10:45 Discussion of two LHCb papers: PAPER-2014-003: Precision measurement of the $\Lambda_b^0/\overline{B}^0$ lifetime ratio https://cds.cern.ch/record/1643936 PAPER-2014-001: Observation of photon polarization in $B^\pm\to K^\pm\pi^\mp\pi^\pm\gamma$ decays https://cds.cern.ch/record/1644210 We need a person per paper to take care of the collection of comments and to communicate them to the contact authors before the deadline. Please, let me know if you are willing to do so. There will be little time for discussion, therefore, also give comments by e-mail in advance. If I succeeed to change to N328 we may continue until 12:00.

[Bfys-physics] Fwd: no SL5 on stoomboot. final reminder.
by Gerhard Raven 23 Jan '14

WARNING: last change to object! Unless you object before the weekend, this _will_ happen. — Gerhard Begin forwarded message: > From: Jeff Templon <templon(a)nikhef.nl> > Subject: [Stbc-users] preliminary conclusion : no SL5 on stoomboot. final reminder. > Date: 23 Jan 2014 11:00:18 GMT+1 > To: "stbc-users(a)nikhef.nl Stomboot MailList" <stbc-users(a)nikhef.nl> > Cc: "stbc-admin(a)nikhef.nl" <stbc-admin(a)nikhef.nl>, programmaleiders(a)nikhef.nl > > Beste Users and Program Leaders, > > So far, nobody told us that they will need SL5 on the upgraded stoomboot. > Furthermore, we've received information from both ATLAS and LHCb that their > "official" code is guaranteed to be compatible with SL6. Our conclusion is > that SL5 is *unnecessary* on the upgraded stoomboot; we plan to upgrade the > entire cluster to SL6 (including all interactive nodes). > > If you disagree with this statement you have until tomorrow afternoon (Friday > 24th) to let us know! > > Original message below. > > Jeff and Ronald > > As announced at the jamboree, the stoomboot cluster will be upgraded.
