Standard Model Higgs Physics at a 4 TeV Upgraded Tevatron

Abstract

We compute an array of Standard Model Higgs boson ($\hsm$) signals and backgrounds for a possible upgrade of the Tevatron to $E_{\rm cm}=4\tev$. Taking $\mt\geq 140\gev$, and assuming a total accumulated luminosity of $L=30\fbi$, we find that a Standard Model Higgs boson with $\mhsm\lsim 110\gev$ could almost certainly be detected using the $\wpm\hsm\rta lνb\anti b$ mode. A Higgs boson with mass between $\sim 120\gev$ and $\sim 140\gev$ or above $\sim 230-250\gev$ almost certainly would not be seen. A Higgs boson with $\mhsm\sim 150\gev$ or $200\lsim\mhsm\lsim 230-250\gev$ has a decent chance of being detected in the $ZZ\rta 4l$ mode. There would also be some possibility of discovering the $\hsm$ in the $WW\rta lνjj$ mode for $150\lsim\mhsm\lsim 200\gev$. Finally, hints of an event excess in the $WW\rta ll νν$ mode due to the $\hsm$ might emerge for $140\lsim\mhsm\lsim 180\gev$. Given the difficult nature of the Higgs boson signals for $\mhsm$ values beyond the reach of LEP-200, and the discontinuous $\mhsm$ range that could potentially be probed, justification of an upgrade of the Tevatron to $4\tev$ on the basis of its potential for Standard Model Higgs boson discovery would seem inappropriate.
