Description
Looking for new laws of elementary interactions is one of the
mandates of the Large Hadron Collider (LHC). One distinguishing
criterion, often used in these searches, is large amount of
missing transverse momentum, carried away by weakly interacting
massive particles. However, this criterion may not be fulfilled
in a number of well-motivated theoretical scenarios. I plan to
discuss several such situations, their characteristic signatures
in the form of multiple leptons, and the criteria for distinguishing
among various scenarios of this kind. In this connection, I wish to
emphasize the usefulness of one type of signals recently emphasized
by us, namely, same-sign trileptons and four-leptons.
