This WEB page summarize the blessed results for the measurement of
the
limit on the BR of the Lambda_b into pK and ppi decay modes. This has
been
produced for the summer conferences 2004 and has been blessed in the B
Physcis Meeting on Thursday June 24, 2004. Here are reported the
updated results that take in account the new values of the PDG 2004 and
have been re-blessed on Thursday June 22, 2005.
There is a complete version of the results: html,
ps, pdf.
Note: In
this analysis the ratio of the production fractions f_Lambda and f_d is
taken from the PDG 2004. Their ratio has been also measured on the data
collected by CDF Run II (public
web page of the analysis). This measurement suggests that the PDG
value is a lower limit, therefore, using the PDG
value we obtain a conservative limit on the BR.
