  Experimental investigations of current shot noise in quantum point contacts
show a reduction of the noise near the 0.7 anomaly. It is demonstrated that
such a reduction naturally arises in a model proposed recently to explain the
characteristics of the 0.7 anomaly in quantum point contacts in terms of a
quasi-bound state, due to the emergence of two conducting channels. We
calculate the shot noise as a function of temperature, applied voltage and
magnetic field, and demonstrate an excellent agreement with experiments. It is
predicted that with decreasing temperature, voltage and magnetic field, the dip
in the shot noise is suppressed due to the Kondo effect.
