TensofGeV

TensofGeV refers to energy or mass scales in particle physics on the order of tens of gigaelectronvolts (GeV), typically ranging from about 10 to 99 GeV. In collider physics, the phrase describes center-of-mass energies, beam energies, or characteristic momentum transfers that fall within this interval. GeV is the standard energy unit in high-energy physics, with 1 GeV roughly corresponding to the mass energy of light hadrons or the kinetic energy scale of many subatomic processes.

At this energy range, a variety of phenomena are accessible. Charm quark production and many light hadrons are common, and the bottom quark system and related resonances lie near the lower end of the tens-of-GeV window (for example, the Upsilon family sits around 9–11 GeV). Tens of GeV is also suitable for studying quantum chromodynamics, hadronization, and flavor physics, as well as for precision tests of electroweak interactions in processes where heavy bosons are not produced on-shell in large numbers. Production of W and Z bosons generally requires higher center-of-mass energies, such as those above roughly 160 GeV for WW production, though some single-boson processes can occur at lower energies.

Experiments operating in the tens-of-GeV range have included fixed-target setups and electron-positron colliders designed to probe heavy-quark and resonance physics, as well as hadron-collider scenarios that reach these energy scales for specific processes. Detectors measure jets, leptons, and hadrons to test quantum chromodynamics, calibrate luminosity, and map resonance structures. The term tens of GeV provides a useful descriptor for a broad and historically important energy window between low-energy nuclear physics and higher-energy frontier programs.
