MeVTeV

MeVTeV is a shorthand term used in high-energy physics to refer to the broad energy range spanning from megaelectronvolts (MeV) to teraelectronvolts (TeV). It highlights the continuum between nuclear and atomic-scale phenomena and collider-scale processes probed by modern experiments.

MeV-scale physics covers nuclear transitions, beta decay, neutron capture, solar and reactor neutrinos, and gamma-ray spectroscopy. Experiments at this scale rely on detectors such as scintillators, germanium detectors, calorimeters, and low-background setups in underground laboratories.

TeV-scale physics concerns high-energy collisions that probe fundamental interactions and particle constituents. Particle accelerators like the Large Hadron Collider reach energies in the TeV range; experiments study Standard Model processes, particle production, jets, electroweak symmetry breaking, and searches for new physics.

Bridging the MeV and TeV regimes requires complementary facilities and techniques, including accelerators spanning MeV to GeV energies, precision spectroscopy, neutrino experiments, and cosmic-ray and gamma-ray observatories. Detector technologies include time projection chambers, Cherenkov detectors, calorimeters, and advanced tracking systems.

MeVTeV is not a single physics theory; instead it describes a spectrum of phenomena and experimental regimes. The term underscores how physical principles apply across energy scales, from nuclear structure and reaction dynamics to quantum fields and potential new physics beyond the Standard Model.
