FOCUS double charm baryon slides

Cartoon of event

A cartoon of an event is shown below (secondary vertices are labeled in the order found, opposite to the order produced): This slide is also available in GIF , PNG , Encapsulated Postscript , or Postscript

Mass plots of single charm particles in FOCUS

The mass plots below are an example of the statistics of singly charmed particles available at FOCUS. The Lambda_c plot is available as GIF , PNG , Encapsulated Postscript , or Postscript
The combined plot of D0 to Kpi, K3pi and D+ to K2pi is available as GIF , PNG , Encapsulated Postscript , or Postscript

FOCUS double charm results

Below is a plot of all double charm baryon candidates which were searched for (shown separately). This plot is available as GIF , PNG , Encapsulated Postscript , or Postscript

Below is a plot of all double charm baryon candidates which were searched for (combined). This plot is available as GIF , PNG , Encapsulated Postscript , or Postscript

Below is the same plot as above with the SELEX signal regions shaded. This plot is available as GIF , PNG , Encapsulated Postscript , or Postscript

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. This table is also available as GIF , PNG , Encapsulated Postscript , or Postscript
