[Clas_cascades] Meeting notes 9/24/2010

[Kijun Park]

Hi, Hovanes.

Overall, it is good shape in terms of structure wide. Here is my first 
comments from first look. (ver: Sep.23,2010)
Most of them is minor correction or I just want to point out some 
paragraphs which I don't understand what you want to say.
Sincerely yours,
Kijun


(1) EXPERIEMT section: page 2: left middle before decay sequence
 "The acceptance and resolution ... charged particles"  => ??

(2) EXPERIEMT section: page 2: left middle after decay sequence
 "*The the* energy of the initial photon can ...tagging facility"
=> "*The *energy of the initial photon can ...tagger counter."

(3) Fig1. does not show DC index and ST counter. instead there are R1 R2 R3.

(4) Simulation section: page 3 very bottom paragraph
"This study showed that the uncertainty in the acceptance uncertainty of 
CLAS ... ~20%" => ??

(5) Trigger inefficiencies section: very bottom paragraph
sentence 1 "A study of the normalized yield of the 4-track ...two start 
counters in the middle of each sector *are can* have decrease in the 
event rate"
sentence 2 "A possible explanation for this is that the event rates in 
the central counters are higher than the two counters on the edges..."
I think sentence 1 and 2 show a contradiction.

(6)  There is NO fig 2.
Caption : Normalized rate of events => Normalized event rate

(7) Model dependence section :
"...photoproduction depends on the kinematics, *and* we integrate 
..."=>"...photoproduction depends on the kinematics, we integrate ..."

(8) Systematics
".. These variations did not ... the invariant spectrum of the invariant 
mass of [] or [] spectrum." => ??

(9) simple typo:
"... upper limit for the *phptoproduction* cross section *time* the 
branching ratio Br($Phi^{--}$ ... " =>"... upper limit for the 
photoproduction cross section times the branching ratio Br($\Phi^{--}$ ..."

(10) page 5: left top paragraph
".. and therefore we consider the uncertainties due to them negligible." 
=> ??

(11) page 5 left top-middle paragraph
".. is described in Sec. ." => ".. is described in Trigger inefficiency 
section."

(12) Upper limits section:
I know you you will put the proper figure.

(13) Eq(1):
Isn't it necessary to describe $\sigma_x$, $\sigma_b$, $\sigma_e$
