Subject: comments on the PRL draft and on note 5151
Hello everybody,
in preparation for the meeting of tommorrow, hoping to be able to
partecipate somehow, let me send you a few comments.
PRL
=====
text (you certainly ca do better, but I do my part anyway)
------
- page 3, 5th line: reFERRed
A: fixed
- page 3, 23rd line: no abbreviation for Kaluza-Klein
A: fixed
- page 3, 8th line from bottom: fig. # missing
A: fixed
- table I: 1<=Njet
cone 0.7
MET > 80 GeV
\ eta_d in the table, but \eta in the text
A: fixed
- page 4, 2nd column, 19th line: doMINant;
one missing bracket for Z(\to ll)
A: fixed
- page 6, 2nd column, 2nd line: foR
A: fixed
- everywhere, Standard Model ==> satandard model (I favore the uppercase
myself, but I remember having been corrected by a PRL editor)
A: fixed
figures
---------
2) - the meaning of "bin contents normalized as labelled" is not clear
- since the bin is variable the y-axis label (Evt/10 GeV) is not OK
A: The text is actually correct
- the last two bind have 0.3 entries (because you divided by 3 I
guess). this makes the distribution partly regular, partly
differential. I find this confusing. Is there a better way to put it?
A: fixed
3) in the\delta\phi plot the x-axis is in radians but the y-axis label
says "Evt/5 degrees": slight formally inconsistent
A: We will fix this
4) a caption more descriptive would be suitable (what are the three curves?)
A: fixed
contents
----------
- what about the systematics on the background? they are quoted in a
figure caption but not in the text. furthermore, a brief discussion of
the sources of uncertainty might be appropriate
A: fixed
- a K-factor is introduced in page 4, but it is never referres to when
the scale exclusion is discussed. what is the real use of it?
A: fixed
Now CDFNOTE 5151
=================
- inconsistency between fig. 28 and 27: what happens to the events with
MET>180?
A: We can check exactly what cuts these events fail
- fig. 28 and 29 same comment as for fig 2 of the PRL
A: same answer as above
- page 26: why 7087 events Z\to e+e- + jets and not 16540 of page 22 ?
A: Different MC sample are used; the result is the same
- page 26: sigma(Z\to e+e-)normalized = 306 pb, w.r.t. sigma_PYT=309 pb ?
so close? instead for W there is a difference (2816 w.r.t. 3220 pb)
A:Different MC sample are used; the result is the same
- I would like to have a break-up of the systematics on Z->\nu\nu
A: Major is the luminosity since we directly normalize
to data; we say this in the text now
- why we do not depend on K-factor while D0 does?
A: It is not a matter of dependence. We have now added
limits for K factors of both 1.0 and 1.3.
that's it for the time being
cheers
Andrea
