Comparison between FOCUS and SELEX
Below is a plot of the FOCUS data for the two SELEX decay modes with the SELEX regions shaded (in portrait and landscape modes).
These plots are available in:
GIF portrait , GIF landscape ,
PNG portrait , PNG landscape ,
Encapsulated Postscript potrait, Encapsulated Postscript landscape,
Postscript portrait, or Postscript landscape
The FOCUS plots of the two SELEX decay modes are combined with a table showing how the production of double charm baryons relative to
Lambda_c baryons must be greater than a factor of 40-100 more in SELEX than FOCUS if both results are taken at face value. This slide
is availabe in portrait or landscape and in several formats:
GIF portrait , GIF landscape ,
PNG portrait , PNG landscape ,
Encapsulated Postscript potrait, Encapsulated Postscript landscape,
Postscript portrait, or Postscript landscape
Table of expected yields in FOCUS
The table below indicates the expected yield of doubly-charmed baryons given some reasonable assumptions.
