Please give a brief summary of your poster
CDF II has reconstructed a signal of about 900 Lb->Lc+ pi-pi+pi- decays from a data sample of 2.4 fb-1 of ppbar collisions at sqrt(s)~2TeV collected with the displaced vertex trigger. Several resonant decay modes have been observed for the first time, including
Lb->Lc(2595)+[Lc pi+pi-]pi-,
Lb->Lc(2625)+[Lc pi+pi-]pi-,
Lb->Sigma(2455)++[Lc pi+]pi-pi-,
and Lb->Sigma(2455)0[Lcpi-]pi+pi-.
We present the Lb->Lc+ pi-pi+pi- signal extraction and the preliminary measurement of the relative branching fractions of the above resonant Lb decay modes.
