multiTeV

multiTeV, sometimes written as multi-TeV, is a descriptive term used in physics to denote energies in the multi-TeV range, typically above 1 TeV (teraelectronvolt). It is not a separate unit but indicates a scale of energy used to discuss experiments and phenomena at high energies.

In particle physics, multiTeV energies are reached in collider experiments: the Large Hadron Collider operates at collision energies around 13 TeV, and future facilities such as the Future Circular Collider or a multi-TeV linear collider aim for tens to hundreds of TeV to explore physics beyond the Standard Model. The multi-TeV regime is of interest for producing heavy particles, probing electroweak processes at high scales, and testing theories that predict new resonances or extra dimensions.

In high-energy astrophysics, multi-TeV refers to gamma rays or cosmic rays with energies above about 1 TeV. Ground-based Cherenkov telescopes detect photons in the TeV range, and ongoing and planned observatories extend observations to higher energies. The TeV-scale is a benchmark for experimental reach and theoretical models, distinguishing mid-TeV energies from lower GeV-scale energies and higher beyond-TeV scales. The term therefore serves as a practical shorthand for discussions about experiments and phenomena operating at or above TeV energies.
