[Halld-physics] talk for W&M

[Kei Moriya]

Dear all,

Thank you for listening to my practice last week for
my talk this Friday at William & Mary, and again for
the many comments that people sent in afterwards.
I would also like to thank those who sent me pictures
and figures for use. For groups developing detectors,
if you would like a different picture to be used, please
let me know.

I have updated the talk, and the talk can be downloaded
from the DocDB at:
http://argus.phys.uregina.ca/cgi-bin/private/DocDB/ShowDocument?docid=2384

I have added a few estimates of yields and figures based on
the simulation studies I have been doing.

For justification
of these, please see the slides at the following:
http://dustbunny.physics.indiana.edu/~kmoriya/2014-01-20-Xi/

I can explain these figures and estimates at the next
physics meeting next Monday. The current results are:

- we will produce 3M K+ K+ Xi- events with a 5 nb cross section
   (all yield results for Phase IV running)
- the reconstruction efficiency for Xi- is 4.2%
- the mass resolution of Xi-(1820) -> Lambda K- is 10 MeV
- the vertex resolution in z for the K+ in Xi-(1820) production is
   ~0.05 cm, with worse resolution for secondary vertices
- we will produce 600k Xi-(1820) events with a 1 nb cross section
- the reconstruction efficiency for Xi-(1820) is 1.6%

My talk is this Friday, so please send in any comments
or further suggestions by then. There will be some small
changes of course, but unless there are strong objections,
I think the talk is in it's semi-final form.

Thanks again for your comments and suggestions,

	Kei
