SUPERSYMMETRY REACH OF AN UPGRADED FERMILAB TEVATRON COLLIDER

examine the capability of a root s = 2 TeV Fermilab Tevatron p (p) over bar collider to discover supersymmetry, given a luminosity upgrade to amass 25 fb(-1) of data. We compare with the corresponding reach of the Tevatron main injector (1 fb(-1) of data). Working within the framework of minimal supergravity with gauge coupling unification and radiative electroweak symmetry breaking, we first calculate the regions of parameter space accessible via the clean trilepton signal from (W) over tilde(1) (Z) over tilde(2) --> 3l + E(T) production, with detailed event generation of both signal and major physics backgrounds. The trilepton signal can allow equivalent gluino masses of up to m (g) over bar similar to 600-700 GeV to be probed if mo is small. If m(o) is large, then m (g) over bar similar to 500 GeV can be probed for mu < 0; however, for mu > 0 and large values of m(o), the rate for (Z) over tilde(2)--> (Z) over tilde(1)l (l) over tilde is suppressed by interference effects, and there is no reach in this channel. We also examine regions where the signal from (W) over tilde(1)<(W)over bar over tilde>(1) --> l (l) over bar+ E(T) is detectable. Although this signal is background limited, it is observable in some regions where the clean trilepton signal is too small. Finally, the signal (W) over tilde(1) (Z) over tilde(2) --> jets + l (l) over bar + E(T) can confirm the clean trilepton signal in a substantial subset of the parameter space where the trilepton signal can be seen.
