Translation for 'Femtometer' from English to French

femtometer <fm> [Am.]

femtomètre {m} <fm>unit

• A prominent example, and the first case considered as such in theoretical physics, occurs at high energy in quantum chromodynamics when quarks and gluons are free to move over distances larger than a femtometer (the size of a hadron).
• At ordinary temperatures or densities this force just confines the quarks into composite particles (hadrons) of size around 10−15 m = 1 femtometer = 1 fm (corresponding to the QCD energy scale ΛQCD ≈ 200 MeV) and its effects are not noticeable at longer distances.
• Femtotechnology is a hypothetical term used in reference to structuring of matter on the scale of a femtometer, which is 10−15 m.
• , suppressed couplings to protons relative to neutrons and electrons at femtometer range, could explain the data.
• The femtometre (American spelling femtometer) symbol fm derived from the Danish and Norwegian word [...] 'fifteen', [...]) is a unit of length in the International System of Units (SI) equal to 10−15 metres, which means a quadrillionth of one metre.
