A Search for fully hadronic decay modes of the B(c) meson at CDF

Abstract

I present a search for the fully hadronic decays of the bottom-charm meson $B_c$ in the mass range 5.6 to 6.8 GeV. The decays $B_c \to J/\psi \pi^+$ and $B_c \to J/\psi \pi^+ \pi^- \pi^+$ are reconstructed using a data sample corresponding to an integrated luminosity of 109 pb$^{-1}$ of $pp$ collisions at $\sqrt{s} = 1.8$ TeV collected with the Collider Detector at Fermilab. Upper limits on the cross section times branching ratio for each decay mode relative to $B^+ \to J\psi K^+$ are presented as a function of the $B_c$ mass.
