Search for a new heavy gauge boson W′ with event signature electron+missing transverse energy in pp̄ collisions at √s=1.96TeV

We present a search for a new heavy charged vector boson W′ decaying to an electron-neutrino pair in pp̄ collisions at a center-of-mass energy of 1.96 TeV. The data were collected with the CDF II detector and correspond to an integrated luminosity of 5.3fb-1. No significant excess above the standard...

Description
Summary:We present a search for a new heavy charged vector boson W′ decaying to an electron-neutrino pair in pp̄ collisions at a center-of-mass energy of 1.96 TeV. The data were collected with the CDF II detector and correspond to an integrated luminosity of 5.3fb-1. No significant excess above the standard model expectation is observed and we set upper limits on σ•B(W′→eν). Assuming standard model couplings to fermions and the neutrino from the W′ boson decay to be light, we exclude a W′ boson with mass less than 1.12TeV/c2 at the 95% confidence level. © 2011 American Physical Society.
