SIGNALS FOR MINIMAL SUPERGRAVITY AT THE CERN LARGE HADRON COLLIDER - MULTIJET PLUS MISSING ENERGY CHANNEL

We use ISAJET to perform a detailed study of the missing transverse en ergy is not an element of(T) plus multijet signal expected from superp article production at the CERN LHC. Our analysis is performed within t he framework of the minimal supergravity model with gauge coupling uni fication and radiative electroweak symmetry breaking. We delineate the region of parameter space where the is not an element of(T) supersymm etry signal should be observable at the LHC and compare it to the regi ons explorable via searches for sleptons and for chargino or neutralin o production. We confirm that, given a data sample of 10 fb(-1), m(g) similar to 1300 GeV can be explored if m ($) over bar q much greater t han m ($) over bar q, while m ($) over bar g similar to 2000 GeV can b e probed if m ($) over bar q similar or equal to m ($) over bar g. We further examine what information can be gleaned from scrutinizing this event sample. For instance, the multijet multiplicity yields informat ion on whether squark production makes a significant contribution to t he observed is not an element of(T) sample. Furthermore, reconstructin g hemispheric masses may yield a measure of m ($) over bar g to simila r to 15-25% if gluinos are lighter than 700-800 GeV. Finally, for favo rabl<is not an element e ranges of parameters, by reconstructing masse s of tagged b ($) over bar b jet pairs, it may be possible to detect H iggs bosons produced via sparticle cascade decay chains.
