1. Bottom Baryon States (not seen yet but known to exist) to Discover with Clean Cuts – to either see and measure mass for first time or measure a braching ratio that was not measured before. Arie Bodek, Yonsei Chung.

1. State 6.8 GeV (measure mass –see predictions below – final state is Lambda C+ Kaon- with the LambdaCseen in either Phi-P (cleaned) or PKPi (cleaned) The state cbd - which has not been seen yet - decays has follows: d (-1/3) -------------------------------------------------------------------- c (+2/3 ---------------------------------------------------------------------- LambdaC (dcu) b(-1/3) ---------------c (+2/3) --------------------- --| u (2/3) | cbar(-2/3)-----| ubar(2/3)-- | | Kaon (s-ubar) -----w{+} --------------- -s(-1/3) ----(or d)-----(cabbibo sup pion) SAMPLES 1: Lambda B decays to Lambda C and a pion (clean up and put mass of Kaon) – long lived. Control sample is LambdaB to LambdaC and Kaon and reflection of LambdaB to LambdaB pion (LambdaB to LambdaC Kaon for first time) Sample 2 : Phi –P – Pi (Clean up, require Phi P to be a Lambda C, put mass of Kaon)
2. 5.8 GeV (measure mass –see predictions below – final state is Lambda C+ Kaon- with the LambdaCseen in either Phi-P (cleaned) or PKPi (cleaned) The state cbd - which has not been seen yet - decays has follows: d (-1/3) -------------------------------------------------------------------- u (+2/3 ---------------------------------------------------------------------- LambdaC (dcu) b(-1/3) ---------------c (+2/3) --------------------- --|--------------------- | -| ubar(2/3)-- | | pion (d-ubar V-A sup) -----w{+} --------------- -d(1/3) --------(or-s)--- ( cabbibo sup.
