If the effective cosmological constant $\Lambda$ of the present universe isdue to physical processes in the early universe operating at temperatures justabove the electroweak energy scale, it is possible that new particles withmulti-$\text{TeV}$ masses exist. These ultraheavy particles may (or may not)show up at the Large Hadron Collider (LHC) or a next-generation proton-protoncollider. If they do, they may provide new insights into the early universe andfundamental physics.
