Figure 2.9

$E/p$ distribution of electrons from $W$ decays.
The solid (dotted, dashed) histogram uses 8\% X$_o$
(17\% X$_o$, 30\% X$_o$) of
the detector material up to the middle of the CTC.

Figure 2.10

The $ \eta_{\rm det} $ distributions of plug $W$ electrons.
Events in CTC sample are concentrated in the low
$ \eta_{\rm det} $ because the CTC track finding efficiency
quickly falls. The SVX sample events are populated more uniformly
in $ \eta_{\rm det} $.

Figure 2.11 
The lepton charge signed pseudorapidity distribution of
the lepton
and
the photon
in the $W\gamma$ production.

Figure 2.12 
The lepton charge signed pseudorapidity distribution of
the lepton
and
the photon
in $Z\gamma$ production.

Figure 2.13 
The data point in the
left figure
represents the CDF measurements of
$M_W$ and $M_{\rm top}$, and the point in the
right figure
represents the CDF II estimate for 2~fb$^{1}$.
The curves are from a calculation~\protect\cite{mwvsmtop} of the dependence of
$M_W$ on $M_{\rm top}$ in the minimal standard model using several Higgs
masses. The bands are the uncertainties obtained by folding in quadrature
uncertainties on $\alpha(M_Z^2)$, $M_Z$, and $\alpha_s(M_Z^2)$.

Transverse mass distributions for $W\rightarrow e\nu$ and
$W\rightarrow \mu\nu$
from
Run Ia
($a$ and $b$) which gave a $\pm 180$ MeV/c$^2$ measurement
of the $W$ mass,
and the equivalent preliminary distributions from the first 67~pb$^{1}$
of
Run Ib
($c$ and $d$).

background (dashed line).
Right:
Reconstructed photon conversion vertex density in the
$r$$\phi$ plane for the innermost superlayer in the CTC,
folded into 1/30 of the
circumference (this layer has 30fold symmetry).

Figure 2.16 
Change in derived $W \rightarrow e\nu$ mass
($\Delta M_W^e$) versus the
signed deviation in units of standard deviations
from the average Run Ia $W$ asymmetry measurement
($\zeta$) for various PDFs. The lower edge of the fitting region
is
$(a)$ 60, $(b)$ 65
, and
$(c)$ 70~GeV
Note that raising the lower edge of the fitting region makes
the result less sensitive to PDFs, particularly for variation
not correlated to the asymmetry.

candidates along with background and signal expectation.
The inset is the fit to $M_T^W > 110$ GeV/c$^2$.

Model calculation. The solid line is a binbybin calculation of
A$_{FB}$ (MRSA), and the dashed line is the same calculation integrated
over the two mass regions.
