SiD Letter of Intent
Letter of intent describing SiD (Silicon Detector) for consideration by the International Linear Collider IDAG panel. This detector concept is founded on the use of silicon detectors for vertexing, tracking, and electromagnetic calorimetry. The detector has been cost-optimized as a general-purpose detector for a 500 GeV electron-positron linear collider.Letter of intent describing SiD (Silicon Detector) for consideration by the International Linear Collider IDAG panel.

W production and the search for events with an isolated high-energy lepton and missing transverse momentum at HERA
A search for the leptonic decays of W bosons produced in the reaction e^+
p\to e^+ W^\pm X at a centre-of-mass energy of 300 GeV has been performed with
the ZEUS detector at HERA using an integrated luminosity of 47.7 pb^-1 . Three
events consistent with W\to e\nu decay are found, giving a cross section of 0.9
+1.0 -0.7 \pm 0.2 pb, in good agreement with the Standard Model prediction. The
corresponding 95% C.L. upper limit on the cross section is 3.3 pb. A search for
the decay W\to \mu\nu has a smaller selection efficiency and yields no
candidate events. Limits on the cross section for W production with large
hadronic transverse momentum have been obtained. A search for
high-transverse-momentum isolated tracks in events with large missing
transverse momentum yields results in good agreement with Standard Model
expectations, in contrast to a recent report by the H1 collaboration of the
observation of an excess of such events.Comment: 17 pages including 7 figures and 2 tables, final version for
