Abstract

We study the cross-section of production of a single W- boson in association with a neutrino through the process e-p. e-g*p. neW-p. Additionally, we obtain limits on the anomalous couplings... and.. of the W+W-. vertex at the Large Hadron electron Collider (LHeC) and the future circular collider hadron-electron (FCC-he). The impact of the polarized beam due to the electron is also analyzed. Our best limits for... and.. at the 95% C.L. are:....=.+/- 0.0017, lg =.0.0053 (unpolarized electron beam) and Dkg =. 0.0013, lg =.0.0046 (polarized electron beam) identifying the W- boson through the hadronic decay channel. In addition, the e-g*. neWcollision is one of the clean, pure and simple processes to probe the W+W-. coupling without the complications of QCD backgrounds.
