Query: A New measurement of the W boson mass at D0   We present a new measurement of the $W$ mass using the $W\to e\nu$ data from
the D\O forward detectors at the Fermilab Tevatron $p \bar p$ Collider. This is
the first measurement of the $W$ mass with electron candidates in the range
$1.5 < \mid \eta \mid < 2.5$. We present measurements of the $W$ mass using the
transverse mass, the electron transverse momentum and the neutrino transverse
momentum, and the combined result using all three techniques. The combination
of the forward detector measurement with the previous measurements using the
central detector gives a new precise measurement of the $W$ mass from D\O.
