  Preliminary results from two recent CDF b physics analysis are presented. The
first obtains sin(2beta) = 0.79 + 0.41 -0.44 from a measurement of the
asymmetry in B0, B0bar to J/psi K_short decays, providing the best direct
indication so far that CP invariance is violated in the b sector. The second
obtains new results on the parity even (A_0 and A_par) and odd (A_perp)
polarization amplitudes from full angular analyses of B0 to J/psi K*0 and B_s
to J/psi phi decays.
