theory of physics, a Lorentz scalar is a scalar expression whose value is invariant under any Lorentz transformation. A Lorentz scalar may be generated from...

numbers Scalar (physics), a physical quantity that can be described by a single element of a number field such as a real number Lorentz scalar, a quantity...

particles transform like a scalar under Lorentz transformation (i.e. are Lorentz invariant). A pseudoscalar boson is a scalar boson that has odd parity...

under any Lorentz transformation. The only fundamental scalar quantum field that has been observed in nature is the Higgs field. However, scalar quantum...

In physics, the Lorentz transformations are a six-parameter family of linear transformations from a coordinate frame in spacetime to another frame that...

preserve scalars, while in relativity, Lorentz transformations or space-time translations preserve scalars. The term "scalar" has origin in the multiplication...

quantities are built out of scalars, four-vectors, four-tensors, and spinors. In particular, a Lorentz covariant scalar (e.g., the space-time interval)...

article Lorentz transformation for details. A quantity invariant under Lorentz transformations is known as a Lorentz scalar. Writing the Lorentz transformation...

Lorentz scalar invariant shows that the total derivative with respect to proper time d d τ {\displaystyle {\frac {d}{d\tau }}} is likewise a Lorentz scalar...

}} . Therefore, ψ † ψ {\displaystyle \psi ^{\dagger }\psi } is not a Lorentz scalar and ψ † γ μ ψ {\displaystyle \psi ^{\dagger }\gamma ^{\mu }\psi } is...
