Query: Diquark Bose-Einstein Condensation and Nuclear Matter   We study a possible transition between symmetric nuclear matter and the
diquark Bose-Einstein condensate (BEC) matter at zero temperature. We find that
chiral restoration transition is first order and coincides with deconfinement.
We investigate various possible coexistence patterns which may emerge from the
first order deconfinement phase transition by assuming different values for the
critical deconfinement chemical potential. If deconfinement takes place at
higher chemical potential, there exists a mixed phase of nuclear and chirally
restored diquark BEC matter. This coexistence region extends over a large
density region for a bigger diquark BEC or a weaker diquark-diquark
interaction. For model parameters with heavy diquark in vaccum, phase
transition to diquark matter becomes of second-order. We also show that in the
case of precocious deconfinement, droplets of nucleons and droplets of chirally
restored Bose-Einstein condensed diquarks coexist surrounded by non-trivial
vacuum. We show that a early deconfinement and a weak repulsive diquark-diquark
interaction soften the equation of state. We propose a scenario in which
nuclear matter saturates due to the formation of the diquark BEC and
deconfinement phenomena. In this picture, instead of repulsive vector-meson
exchange the compressibility of the equation of state is related to a repulsive
diquark-diquark interaction. In general, we emphasize the importance of a
diquark BEC phase at rather low density before quark BCS-pairing transition.
