Title:
"W'-like Resonances in the tb Decay Channel"
Abstract:
Abstract: We use the tools of the single top analysis to search for
resonant tb (+c.c) pair production in a sample of approximately 1 fb-1
of pp collisions at the Fermilab Tevatron. We look for unexpected
structure in the spectrum of the invariant mass of the reconstructed W
boson and two leading jets: M(Wjj). Expected contributions from
Standard Model (SM) processes are derived from selections and
background studies of the single top analysis. Resonant tb production
is modeled as a simple W' with SM-like couplings to fermions. We
establish expected sensitivity over the W' mass range from 300 GeV/c2
to 950 GeV/c2, derive 95% CL upper limits for A * BR to tb as a
function of the W' mass and compare to expectation.
