Physics Potential of a Tevatron Tripler

Abstract

We explore the capabilities for new physics discovery in proton-antiproton collisions at 5.4 TeV center-of-mass energy with luminosity $10^{33}c{m}^{-2}{s}^{-1}$ at a Tripler upgrade of the Tevatron collider. The prospects are robust for the usual Higgs boson and supersymmetry benchmarks. With an integrated luminosity of 40 fb${}^{-1}$, discoveries at 5$\sigma$ could be made for a standard Higgs boson of mass $\text{alt}680$ GeV (600 GeV for 10 fb${}^{-1}$), a lighter chargino of mass $\text{alt}380$ GeV, and an extra $Z$ boson of mass $\text{alt}2.6$ TeV; four-fermion contact interactions from new physics with scale $\text{alt}74$ TeV could be excluded at the 95% confidence level.
