[Bfys-physics] LHCB-PAPER-2011-030-001-COMMENT-012
by Tjeerd Ketel 28 Feb '12

28 Feb '12

Dear all, The comments we posted at 8 February about LHCB-PAPER-2011-030 have been answered in detail by Valerie Gibson. - "Pseudo-decay time" is guide line from Editor Board. - "Mixed events" were tried for background. It turned out difficult to get the right mix of photons due to correlations. The background fitted well at low pT. - The Chigen authors did produce the specific predictions. - and more ... see http://cdsweb.cern.ch/record/1427716 Best regards, Tjeerd ---------- Forwarded message ---------- Date: Tue, 28 Feb 2012 13:57:21 +0100 From: CERN Document Server Submission Engine <cds.support(a)cern.ch> To: tjeerd(a)nikhef.nl Subject: LHCB-PAPER-2011-030-001-COMMENT-012 (a comment has been made on your comment) Dear LHCb Colleague, The comment (LHCB-PAPER-2011-030-001-COMMENT-006) that you made on LHCB-PAPER-2011-030-001 (entitled: 'Measurement of the cross-section ratio $\sigma(\chi_c \to J/\psi \gamma) / \sigma(J/\psi)$ for prompt $\chi_c$ and $J/\psi$ production at $\sqrt{s} = 7$ TeV') has itself been commented on by Tjeerd Ketel [CERN - PH/ULB] (tjeerd(a)nikhef.nl).

[Bfys-physics] Comments on Paper-2012-030 discussed last Friday
by Tjeerd Ketel 06 Feb '12

06 Feb '12

Dear all, I have collected the comments proposed during the Bfys Meeting last Friday in the pdf and tex attachments. A large part from my side consisted of rewriting section 3.0. I like to do so, but I do not want to insult the authors. Please, have a look and correct me, before I send it in on Wednesday. Best regards, Tjeerd PS The comments that we send in last week seemed to be useful and were quickly answered in detail. See https://cdsweb.cern.ch/record/1420599?ln=en
