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 energy is not an element of(T) plus multijet signal expected from superparticle production at the CERN LHC. Our analysis is performed within the framework of the minimal supergravity model with gauge coupling unification and radiative electroweak symmetry breaking. We delineate the region of parameter space where the is not an element of(T) supersymmetry signal should be observable at the LHC and compare it to the regions explorable via searches for sleptons and for chargino or neutralino production. We confirm that, given a data sample of 10 fb(-1), m(g) similar to 1300 GeV can be explored if m ($) over bar q much greater than m ($) over bar q, while m ($) over bar g similar to 2000 GeV can be probed if m ($) over bar q similar or equal to m ($) over bar g. We further examine what information can be gleaned from scrutinizing this event sample. For instance, the multijet multiplicity yields information on whether squark production makes a significant contribution to the observed is not an element of(T) sample. Furthermore, reconstructing hemispheric masses may yield a measure of m ($) over bar g to similar to 15-25% if gluinos are lighter than 700-800 GeV. Finally, for favorabl<is not an element e ranges of parameters, by reconstructing masses of tagged b ($) over bar b jet pairs, it may be possible to detect Higgs bosons produced via sparticle cascade decay chains.
