  • noun

  • Specialized
: pseudoscalar
  • The concept of a pseudoscalar is important when analyzing systems that exhibit parity violation.

Examples

  • Astrophysical constraints on ksub imply (n5, n18) that the corresponding pseudoscalar coupling to photons is greater than the Planck energy.

    Academic text (2004)

  • In theoretical physics, a pseudoscalar changes its sign when the coordinate system is reflected.

  • Researchers found that the pseudoscalar nature of the field affected the results of their experiments.

Morphology

pseudoscalar = scalar (semi-transparent) = pseudo + scalar

The prefix pseudo- and the base scalar are clear, but the technical physics meaning is specialized and not fully predictable for a novice.

Etymology

Pseudoscalar comes from pseudo- meaning 'false' and scalar, which means a single number or quantity. A pseudoscalar is therefore a quantity that looks like a scalar but, when you view it in a mirror, it becomes the opposite and 'changes sign'.
