[Halld-physics] MENU Proceedings for KSigma Beam Asymmetry / comments from Elton

[Elton Smith]

Hi Nilanga,

I have several suggestions to clarify the text. (Note comments are 
easier if the draft has line numbers):

General: In the text you use $t$ and $u$ but you should probably use 
$-t$ and $-u$ consistently. In some cases the sentences are incorrect 
with out the "-".

Introduction.
- middle second paragraph: "....at lower energies." -> "...at energies 
below 5? GeV"  (state what it means to be lower energy.
- Fig 1 caption: ... gp -> K+S0, based on figure in ...

GlueX Detector.
- Middle paragraph: ...barrel calorimeter. THE start 
counter....particles while THE barrel calorimeter...."

Method.
p 2
- First paragraph. remove "to have at least one photon," (redundant, I 
assume, with neutral shower below). Or at least one neutral shower?
- No need to change paragraphs after first sentence.
- second paragraph. ...K+ tracks -> K+ vertices...-
- Move sentence beginning with "A cut of THE FCAL shower quality..." to 
third paragraph to replace sentence "This is shown in Fig.4."
- third paragraph: Have you mentioned that accidentals are subtracted? 
(accidentals are shown in Fig 3) You need to say that accidentals have 
been subtracted, at leas I assume so.
- fourth paragraph: You should add a sentence such as "We take the 
events in the peak below -t<3 GeV2 to be generated by t-channel 
exchange, and the events in the
peak -t>11 GeV2 to be generated by u-channel exchange." [I assume this 
is the way you select t- and u-channel processes?]

p 3
- bottom: "PARA is the configuration when the polarization plane....
- last line: end the line with a colon (:), not a period (.).

p 4
- Eq3, should have a comma (,) at the end.
- Sentence after Eq3: ...lab floor and THE K+ production...
- no new paragraph after line 4 and remove comma (,) before equations.
- Eq 4 and 5, should the "~" be replaced with the proportional sign?
- Following Eq 5, second sentence beginning with "P_par and P_perp are 
magnitudes....." is redundant with sentence following Eq3, so eliminate.
- Remove comma at end of line before Eq 6
- Second line after Eq 6: added -> included.... polarization from ITS 
nominal.....
- Last line, "THE beam asymmetry..."

Results.
- Fig. 9 and 10 captions. Somewhere "total uncertainties" should be 
defined. Alternatively, replace this term with "quadrature sum of 
statistical and systematic uncertainties"
- Fig 9 caption:  ...while horizontal error bars indicate the 
RMS...used. THE solid red circles...curve shows the prediction from the 
RPR-2007....
- Fig. 10 caption: ....solid circles correspond to THE combined....
...while THE horizontal error bars indicate the RMS widths of the -u bins.

Conclusion.
- first line: ...Sigma in THE exclusive..
- second line: ....beyond THE resonance...   asymmetry results in the 
t-channel are close to unity.....
- fourth line: .... never been measured before and results in a value 
Sigma~0.2-0.6. This indicates that in this kinematic domain.....

References.
- All citations have two double quotes at the beginning of the titles 
and should be changed to a single double quote. At the end of the title 
only a single pair is needed also.
