Measurement of Charged Current Deep Inelastic Scattering Cross Sections 
   with a Longitudinally Polarised Electron Beam at HERA

                 ZEUS Collaboration

Measurements of the cross sections for charged current deep inelastic 
scattering in e-p collisions with longitudinally polarised electron beams 
are presented. The measurements are based on a data sample with an 
integrated luminosity of 175pb^-1 collected with the ZEUS detector at HERA 
at a centre-of-mass energy of 318 GeV. The total cross section is given for 
positively and negatively polarised electron beams. The differential 
cross-sections dsigma/dQ2, dsigma/dx and dsigma/dy are presented for 
Q2>200 GeV2. The double-differential cross-section d^2sigma/dxdQ2 is 
presented in the kinematic range 280<Q2<30000 GeV2 and 0.015<x<0.65. 
The measured cross sections are compared with the predictions of the 
Standard Model.
